If you have a ventilation design in mind, or you just want to buy a simple table fan, it’s important to know where to buy. There is an abundance of fan manufacturers and fan suppliers out there. If you have a brand name in mind, sticking with what you know works is often wise. But if you aren’t familiar with the full range of fan uses, designs, and specifications, you’ll need to find a fan company that sells a variety of brands and models that meet your needs. Even if you’re an industry professional, it can be impossible to know...

According to the EPA’s Engineering and Research Laboratory, using ventilation exhaust in industrial settings is especially important when considering the impact of manufacturing and synthetic chemicals on the environment. Especially important is the risk to human health that presents itself to industrial workers on a daily basis. Commercial fans help reduce the impact of pollutants for people who work around welding, blasting, grinding, polishing, solvents, dip tanks, oil mists, dusts, or tiny fibers. Exhaust fans draw gasses away from the main source, reduce noise from output, and lower the concentration of emissions from the entire process. A well-designed ventilation system...

Whole house fans provide cooling by exhausting hot air from the attic and living spaces. They are sometimes confused with attic fans. Attic fans can help keep a house cooler, but they only remove hot air from attics. Whole house fans are installed in the ceiling, in a central location of a home (or sometimes in a wall, but rarely so). They are located in a place where air can blow into the attic. Whole house fan blades are large and provide significant ventilation pressure to cool a house. This type of fan can exchange the air in a 2400-square...

Whole house fans are a great alternative to air conditioning. They can be used at night when air conditioners are turned off, or they can be used alone. Using a whole house air movement fan alone can cool effectively when temperatures reach 82 degrees F and below, and windows can stay open to let fresh air in. Rather than install expensive air conditioning units, use a more eco-friendly, cost-efficient ventilation design to keep homes cool. Some people object to whole house fans because of the noise they create. Whole house fans can be noisy at times, but this is due...

Anytime the temperature reaches 82 degrees F and above, you can rely on your attic fan to shave 30 percent off air conditioning costs. Attic fans exhaust hot attic air that can turn a home into a sauna. Without proper attic ventilation, rooftops, attics, and ceilings get super-heated, making internal temperatures soar. By drawing hot air out and allowing fresh air to come in, the hottest part of the house will stay cool, helping the rest of the house feel comfortable. In construction, installing whole house attic fans creates an attractive incentive for homebuyers. For contractors and homeowners, retrofitting an...
