Exhaust fans are also used to provide proper ventilation in a specific area. However instead of providing continuous flow of air, exhaust fan pulls away the hot and stale air out of a certain area. This is to keep a balance flow of air and to avoid conflicting temperatures.
Exhaust fans are often mounted to walls and ceilings that is why they have a distinct flat-like construction. They also have aluminum shutter and metal guards which offer air-open and gravity-close operation.
Exhaust fans are available in different sizes to accommodate residential and commercial applications. Industrial exhaust fans are sturdier and more powerful compare to those that are used for residential applications. Industrial exhaust fans also features low-pressure direct drive exhaust and two-three speed settings. TPI is one of the best selling brands of industrial exhaust fans to date and all of their offerings have meet the OSHA standards.
