Some factors to consider when selecting a wall mounted exhaust fan are power sources available such as single phase or three phase power, how clean is the air stream, whether or not gravity shutters or actuator driven shutters are required for your wall exhaust fan, how sensitive is the area to sound and whether a belt driven or direct driven wall exhaust fan is preferred. We offer wall exhaust fan accessories such as weather hoods, single stage and two stage thermostats, modulating thermostats, rheostats or variable speed controllers and variable frequency drives. Various motor options for all wall mount exhaust fans are also available such as, totally enclosed air over or totally enclosed fan cooled motors, explosion proof motors, two speed motors and 50Hz motors for applications out of the United States. The type and size of an exhaust fan required is determined by looking at several factors unique to your application. The most important are the volume of the space, how the space is being used and environmental factors such as humidity and fume levels. A good starting point for selecting your exhaust fan is by calculating your CFM requirements based on complete changes of air in a structure or room in a given time period. Once you have calculated the volume of air in your space (length X width X average ceiling height) measured in cubic feet, you can determine the appropriate air exchange rate by referencing the chart above. In the most severe conditions select the lower number (in the series shown) to change the air more frequently. For moderate conditions, select the mid range. For less severe conditions in cool climates, the higher number will provide adequate ventilation. We carry only the most quality constructed and effective exhaust fans available on the market today permit location of the fan near the area to be ventilated allowing short duct runs and more efficient operation. Roof mounted exhaust fans are perfect for removing unwanted heat or lighter than air fumes that rise to the ceiling. Roof exhaust fans are also perfect for exhausting fumes or smoke from equipment without causing cross winds. We offer direct drive propeller roof exhaust fans for use when large volumes of clean air are required to be removed in an economical way. We offer belt drive propeller roof mount exhaust fans when the installation calls for higher static pressure or when the air is contaminated with smoke or moisture. We can also supply special coatings for our roof exhaust fans such as Epoxy Coatings, Eisenheiss Coatings, Heresite Coatings or Zinc Rich Paint and all Galvanized Construction. Our direct drive centrifugal roof exhaust fans are designed for little to high static pressure applications and can often be used (certain horse powers) with a variable speed controller or rheostat. We offer up blast centrifugal roof exhaust fans for contaminated applications such as grease extraction roof exhaust exhaust fans attached to commercial cooking hoods or commercial dryers with moisture laden air. Belt drive centrifugal roof exhaust fans are used when high CFM (Cubic Feet per Minute) requirements exist. We also supply down blast roof exhaust fans when economical clean air extraction exists such as commercial bathroom exhaust applications. Our down blast roof exhaust fans also maximize protection against adverse weather conditions. Are mounted on a frame with gravity dampers or sometimes motor controlled dampers designed to close when the fan shuts off. This keeps the outside air from entering back into the building when the fan is not in operation. Shutter mount wall exhaust fans are typically shipped fully assembled so you are up and running with minimal installation time. Sometimes the damper can be removed or sold separately. This is helpful for thicker walls and prevents any gaps when the shutter mounted wall exhaust fan isn't deep enough to pass through the full thickness of the wall. Our shutter mounted wall exhaust fans can supplied with a variety of motor options from odp motors for relatively clean air streams to totally enclosed motors for dirty locations to explosion proof wall exhaust fans where combustible or explosive fumes are present. Are essentially an exhaust fan rotated 180º in the wall and typically mounted in a cabinet with a powered damper.
