Heat Guns – More Than Just Safely Removing Paint

Uses Of Heat Guns

Apart from removing paints, heat guns are often used in home and workshops for various other purposes. A few among them are mentioned below:

1. You can buy heat gun online for removing old floor tiles, bumper stickers, decals and several other materials that are fixed with glue.

2. Floor tiles are fragile when cold and can break down when cut to fit into clenched places such as around pipes or molding. Heating the tile with a heat gun makes the process of cutting much easier and more precise.

3. Heat gun is often used to soften the putty around doors and windows. This makes the compound easier to scrape off.

4. To thaw frozen pipes, buy a heat gun, easily available online, as it is much safer than a torch with an open flame. Be careful on soldered joints as the gun can heat the solder if held in place for too long.

How To Use a Heat Gun?

Heat gun is known to remove paint quickly, thereby creating less of a mess than a chemical remover. The gun can work both on latex or oil-base finishes. However, it cannot remove a stain that has soaked into wood.

Install the nozzle before turning the heat gun on. Generally, there are two types of nozzles - one with wide-flare used for most paint-removing jobs, and the round nozzle that works great where heat must be more localized. It is up to you to determine which nozzle is best for a particular job. However, if you need to change nozzles later, cool it for at least five minutes before removing the hot nozzle.

It is necessary to heat only a few square inches at a time and scrape the softened paint off immediately. Prevent the use of nozzle in one place for too long. This will char the paint and wood.

Safety Tips

Once you buy a heat gun online and start using it, you must be aware about the safety precautions you need to follow.

1. You must wear a respirator mask to protect yourself from fumes of the paint.

2. While using this tool, it is necessary to work in a well-ventilated area. That said, opening a window must not be the only option. Either work outdoors or turn on your exhaust fans.

3. Wear a separate set of work clothes and make sure they cover your arms and legs. Be extra cautious by wearing gloves and safety goggles.

4. Heat guns reach high temperature sometimes. Stick to the handle and don't touch the airflow of the tool or the barrel.

5. If you are using an extension cord, make sure it is a heavy duty cord that can carry the load.

6. It is vital to remove paint that has stuck into the nozzle, or else it may create a fire hazard.

Whether you are a professional or have started using this efficient tool from some time now, following the above mentioned safety tips will ensure that neither your work nor productivity gets hampered.

Avoiding Seasonal Allergies All Year Long

There are several different things that can bring annoying and at times unbearable allergy symptoms. To avoid allergens first you have to identify the culprit. When trying to identify the cause of allergy symptoms the most commonly known allergens are looked at first. Identifying the cause of your allergies can make it possible to remove them and enjoy an allergy symptom free life. In this article we will be looking at common causes of allergies and how to avoid them in your home.

Seasonal allergies are commonly a problem in spring, although they can also happen at other times of the year. This is because of the time that plants are pollinating. If you have seasonal allergies in the spring you are most likely allergic to the pollen in the air. Allergy problems in the fall can be due to the decomposition of leaves and other plants. The process can have an increase of mold spores as the last of the moisture in these leaves causes a breakdown.

Dead plants, trees and fallen branches are also commonly ignored allergens. When thinking of items that might cause allergies most people don't give proper credit to the decomposition process as being the allergen producing process that it is. Remove these when they fall, or when they first die, to reduce the amount of mold that is growing around your home since mold causes an increase in allergy symptoms.

Wiping the window daily to remove moisture and cleaning the window track with vinegar or chlorine bleach can reduce allergens in the air by killing the mold and mildew. This condensation can also happen around the faucets and near exhaust fans. Wiping these areas with a solution of water and either chlorine bleach or water and vinegar can keep mildew under control. Using dehumidifiers to keep the humidity down can be helpful when trying to control mold growth as well.

Allergy symptoms are annoying. Once you identify the cause of your seasonal allergies you can avoid them. Cold weather usually increases the symptoms of seasonal allergies. If you remove one possible allergen and your allergy symptoms do not change you need to keep looking for the trigger. By removing one possible allergen at a time you will be able to identify the cause of your allergy symptoms.

Selecting the Proper Bathroom Exhaust Fan

Bathroom ceiling fans are called intermittent ventilation and are used to capture and remove pollutants quickly at the source. The purpose is to exhaust excessive moisture or pollutants before they can spread to other parts of the house. Areas requiring this type of ventilation are bathrooms, kitchens, utility rooms, exercise rooms, workshops, garages and home offices.

Q. What size bathroom exhaust fan will I need?

A. For bathrooms up to 100 square feet in area, it is recommended that an exhaust fan provide 1 cfm per square foot at approximately eight air changes per hour. For proper ventilation, the fan should be left on for around 20 minutes after usage; you may want to install an automatic timer.

For an 8'x5' room with an 8' ceiling = 40 sq ft, you will need a fan rated at 40cfm. For larger bathrooms install a 150cfm fan so that the air can be pulled through the entire room and exhausted at a central location. Or, you can install multi fans; one over the toilet, in the shower, and over the tub. This second method is very effective and provides ventilation where and when it's needed, but both methods work well.

Q. Where should I install the fan?

A. Typically the exhaust points should be located over or near the shower or tub and in an enclosed water closet.

Q. If mirrors stay steamed up or the grill is dripping water, is the fan(s) operating correctly?

A. You could try leaving the bathroom fan on longer to carry out more moisture, or check the design of the duct work. Poor design or damage may prevent the fan from moving the moisture out. You can insulate the ducts and check the roof jack which may be allowing rain to come into the duct, or it could be that condensation from warm, humid air in the house is striking the cold duct surface.

Exhaust Fan at Your Home

Healthy and comfortable home is not only determined by the quality of its cleaning and lighting but also the air circulation. In order for air distribution went well, the room must be supported by a good ventilation system.

But  sometimes is not enough ventilation, therefore, needed a simple tool known as Exhaust Fan
This tool serves to suck the hot air inside the room and throw it out and at the same time sucking fresh outdoor air into the room. Another function is to regulate the volume of exhaust fan air be circulated in the room. To be healthy every room air circulation needs differ according to function.

Turnover air space needed depends on the function of the measured air change per hour. In the bedroom, for example, 2 / 3 volume of space should be replaced with new air every hour. When the vast room 3 x 4 x 3 = 36 m, meaning it requires a change of room air 24 m2/jam.
the presence of exhaust fan is an artificial attempt to optimize changing the air in the room .
TYPES OF EXHAUST FAN
Based on the exhaust fan assembly divided by 3 is: WALL MOUNT, WINDOW MOUNT, CEILING MOUNT.
WALL MOUNTED, mounted on a wall at the back of the wall must deal directly with outside air to exhaust air.
WINDOW MOUNT,  mounted on a glass window (thickness 3-7 mm). When installed in the room in one big room, make sure there is access out into the air in the huge room.

How Paint Spray Booths Work

A spray booth is quite simply a pressure controlled environment which is used to spray paint vehicles in a bodyshop, anything from a family car through to a fighter jet has been sprayed in a spray booth. To ensure the ideal spray booth working conditions which are temperature, air flow and humidity, the environment is equipped with extremely efficient ventilation, made up of at least one or more motors and a couple of burners to heat the air that is blown through.

One of the most fundamental components of the Spray Booth is a good supply of air. Spray Booths require a fair amount of air to be pumped in so as to have a good air supply through the booth. The National Fire Protection Association requires a minimum of 100 feet per minute of air flow past the operator of the spray booth. For the majority of spray booths this essentially means you require a volume source of air somewhere in the region of 8,000 to 10,000 cubic feet of airflow per minute which is typically more air than most buildings can naturally supply.


It is advisable to avoid cheaper filters or fit a filter that doesn't fit properly within its frame as the overspray will not be captured properly and will lead to a build up in the exhaust and on the fan stack, this is a potential fire hazard due to a phenomenon called composting.

The exhaust is the third and final important part of the spray booth setup.  The National Fire Protection Association requires a sturdy steel exhaust chamber with steel filter holding frames as a bare minimum. The size of the exhaust fan which is measured in CFM, is determined by the air required to produce 100 FPM air flow throughout the booth. The CFM measure gives the size of the fan required for a balanced operation of the spray booth.

It is advisable to have the fan mounted high in the exhaust stack and not directly against the exhaust chamber, doing this allows for quieter operation of the fan.

How to Improve Your Bathroom's Ventilation

If your current bathroom doesn't seem to offer you the right amount of ventilation, you can take certain steps to increase air flow and improve your bathroom environment. Blair Harris is the director of Sales and Marketing at A&R Mechanical Services, a Plumbing, Heating and Air Conditioning company that has been serving Amarillo, Texas since 1992, and she thinks that anyone with poor bathroom ventilation ought to try the following in order to combat the problem:

Using an Exhaust Fan

When it comes to improving bathroom ventilation, the use of a fan is truly key. If your bathroom comes equipped with a built-in exhaust fan, don't wait until after you've emerged from the shower to turn it on. Instead, make a habit of running your bathroom fan while you shower so that it can combat all of that added moisture in the air and help keep the atmosphere as cool as possible. If you don't have an exhaust fan in your bathroom, bring in a local plumbing and HVAC company to see if installing one is an option.

Installing a Bathroom Window

You may add a window on one of your bathroom's exterior walls. Not only can a window improve your bathroom's appearance, it can also help tremendously on the ventilation front. If you're not keen on the idea of having a permanent draft in your bathroom, keep in mind that just because you choose to install a bathroom window doesn't mean that you'll always have to leave it wide open. By cracking the window for even a few minutes, you can introduce a stream of fresh air into your bathroom and make it more comfortable in the process.

Cleaning Your Vents
If your bathroom air doesn't seem to be circulating well, clogged or dirty air vents could be to blame. To remedy this, try giving your vents a thorough cleaning. If you're not sure how to tackle the task yourself, hire a local air duct cleaning company to do the job for you. You might be surprised at what a difference a single vent cleaning makes.

Your bathroom is one of those places that you just can't avoid, so you should do what it takes to make it as comfortable as possible. If the air flow in your bathroom isn't what you'd like it to be, contact an experienced plumbing and HVAC company to learn about your options for improving the situation.

Seasoning a Wok With Ease

7. Reduce the heat to low volume and let it sit for about 15 minutes for it to absorb the oil. Color changes will continue in time, especially with frequent usage.

8. Turn off the heat and allow cooling down onto room temperature before you start the next round of seasoning. Wipe out excess oils with a paper towel when it cools. Do not use cold water when cooling the wok. It can damage and undo the process. Hence, cool the wok with boiling or very hot water. Wipe it with a sponge.

9. Dry the wok thoroughly and store.

10. Repeat the process for about 3 to 4 times more. A beautiful black sheen will happen with proper usage.

Another method is to brush the wok with polyunsaturated cooking oil on the surface and place it in an oven. This will take about four hours at 150 degrees Celsius. Every hour, brush the wok with oil around the sides and continue heating. Woks with plastic and wooden handles are not advisable to put inside an oven.

For continuous care
Do not scrub off the protective layer of carbon on the surface of the wok. Scouring pads and detergent soaps are the worst enemies of a seasoned wok. It is best to wash it with hot water and clean the surface with bamboo brush. Dry this with paper towels and lightly put vegetable oil coating before storing.

The bottom part of the wok can be scoured with steel wool so as to take away the burnt materials or residue. If there is an accidental burning of food inside the wok, scour it out and re-season the wok again.

Woks that are new may cause a slight metallic taste onto the first two or three dishes. The metallic taste disappears after several usages. A wok with proper seasoning can make perfect omelets without sticking. For better results, the process of seasoning a wok should be done with patience.

Seasoning a Wok With Ease

Seasoning a wok is the best way to prepare for convenient and conventional cooking. It is more of an art and less of an earthly task.

Woks are prone to rust and buildups of sticky foods, especially if not seasoned properly before usage. Seasoning a wok permits the food to glide smoothly over its surface. Iron and steel woks should be seasoned properly before use.

Stainless steel types need to be treated because they are less porous than iron. Corn and peanut oil are also ideal cooking oils for seasoning because they possess a high heating point. Some even prefer to season woks with the use of an oven.


To start the process, two methods for seasoning are used. The first method is to season a new one or to re-season an old and rusty wok. Below are steps you can follow:

1. Scrub thoroughly the inside and outside surfaces using soap and a steel wool scouring pad. It will remove the new wok's manufacturer's protective coating or even rust on an old wok. The initial coating of a wok prevents rusting during retail display.

2. Rinse with water.

3. For some coatings that are hard to remove, place the wok on a stove with water. Boil until the protective coating dissolves. Pour the water out and scrub with soap and steel wool.

4. Next, heat the wok over high heat until the edges are nice and hot. It will change from a shiny steel gray to blue, then purple to red. Then it will turn into black.

5. Smoke will appear. Turn on the ventilation fan.

6. Using a brush or a sheet of wadded-up paper towel, dip it into corn oil and coat the inside surface with a thin layer of oil. You can tilt the oil in all directions. This can make the surface shine upon each application.

Exhaust Fan Timers Provide A Simple Way to Save Energy

After a long day, sometimes there is nothing better than a good shower, right? Afterwards, you turn on the exhaust fan to prevent moisture. An hour later, you've made something to eat, watched an episode of Glee, and called your friend to chat about it. You hear a faint humming, but can't quite place it. A ha! That bathroom fan is still on, both exhausting air and increasing energy bills. Instead of beating yourself up about it, install exhaust fan timers to eliminate this problem while also reducing energy use.

Enough is enough, and too much is a waste

So, exactly how much is enough? Following a shower or bath, the exhaust fan should be left on no longer than 20 minutes. In this time, the fan is able to exhaust out moisture to prevent mold and the build-up of condensation. Keeping the fan on for less than this can result in the condensation problems that exasperate respiratory-related health issues such as asthma.

Choosing the right timer

Exhaust fan timers come in both mechanical and digital models. A mechanical timer operates the same way in which a classic oven-timer works, with the wind-up mechanism. These typically cost less than the digital timers, and can be set by the minute. Digital timers allow you to choose the operation settings with the push of a button. This type of exhaust fan timer does not allow for minute operation, but can only be set based on five or ten minute intervals.

Time for installation

Saving energy at home is actually much simpler than it may at times appear. The use of exhaust fan timers is a great example of this. By simply setting the timer, you are promoting healthy indoor air quality at home, reducing energy use and costs, and eliminating that horrible feeling of forgetfulness all at the same time.

Building Ventilation

Energy recovery systems have become a popular way to heat and cool homes as well as commercial buildings. Energy recovery applications typically use two fans that provide air through a heat exchanger that "treats" the air by heating or cooling it before it enters the building. Buffalo Blower's plenum and forward curved fans are typically used for energy recovery applications and offer a wide range of performance and flexibility. Generator rooms require a wide range of fans to optimize the performance of generators and other equipment. Exhaust fans are used to prevent heat buildup within the generator room, while supply fans are used to provide fresh air for combustion and efficient generator performance. Room size, space limitations, and mounting capabilities will determine the exact type of fan needed for each specific application. As a leading manufacturer of air moving equipment, Buffalo Blower offers numerous fan types for meeting any generator room specification.

Rooftop exhaust fans are designed to remove heat and odors from buildings to improve air quality and occupant comfort. Areas such as cafeterias, locker rooms, office spaces, restrooms and warehouses often have unique requirements specified by local codes and utilize a wide range of rooftop exhaust fans. To accommodate these various types of environments and ventilation systems, Twin City Fan offers a complete line of products to support every rooftop exhaust application. These applications can range from clean airstreams with minimal filtration all way to high density offices and health care facilities that must comply with extremely stringent regulations. Gravity ventilators are used to equalize a building's positive or negative pressure created by other fans in the system. These ventilators provide natural ventilation and are used for intake and relief applications. Twin City Fan offers both spun aluminum and hooded ventilators, featuring a low silhouette for low roof-lines. Louvered penthouse ventilators are available when aesthetics are not an important factor and feature extruded aluminum louvers. Sidewall exhaust and supply applications require panel fans to move large volumes of air at low static pressures. Panel fans are commonly used on the walls of warehouses and manufacturing facilities to supply outside air or to remove hot or noxious gases in exhaust configurations.  Other typical applications include removing carbon dioxide from produce storage facilities, greenhouse ventilation, and parking garages. Panel fans can be mounted directly to the wall panel, which is especially useful when ductwork is unnecessary. Each fan can be customized to the individual needs of the customer, including aluminum or stainless steel construction, explosion proof motors, gravity or motorized dampers, corrosion resistant coatings, and fully reversible propellers.
