    Chemical-Resistant Blowers

    For resistance to chemicals as well as corrosion, these blowers have a plastic housing. They install in ductwork similar to duct fans, but are for use where high static pressures are present. Use them for equipment cooling, material conveying, drying, ventilating, and exhausting. All blowers have a totally enclosed motor enclosure, which can be used in dirty, dusty, and wet environments.
    Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.
    With Round Outlet and Round Inlet—Totally Enclosed Motor Enclosure

    Wind-Driven Roof-Mount Exhaust Fans

    Image of Product. Front orientation. Contains Annotated. Exhaust Fans. Wind-Driven Roof-Mount Exhaust Fans .
    Designed to spin freely with the slightest breeze, these fans create a vacuum that draws air out from buildings and ventilation systems—no electricity required. They are also known as turbine ventilators. Mount fans on your roof away from wind obstructions.

    Slope Base

    All bases have a square bottom, round top, and flashing to simplify installation.
    To Order: For slope bases, please specify pitch: 1/12-11/12 in increments of 1/12. To determine pitch, use an angle indicator or divide rise by run (see illustration). For instance, if your roof rises 5" in 12" of horizontal space, your pitch is 5/12.
