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 damp environments.

Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.PVC plastic housing offers greater chemical resistance than the fiberglass housing. It resists strong oxidizing acids such as sulfuric acid but will not withstand contact with perchloric acid.

Blowers that cannot be sold to the listed areas are restricted due to energy efficiency requirements.
