Induced Flow Centrifugal Exhaust Fan, Airfoil Blade


The BAIFE Induced Flow, Centrifugal Exhaust Fan is intended for use in exhausting laboratory fumes and hazardous chemicals in such a manner that diminishes the likelihood of concentrated, contaminant-laden air from being re-entrained into the building’s intake or make-up air. This unit is commonly used in exhaust systems for universities, schools, hospitals, research facilities, laboratories, restaurants and wastewater treatment plants.

The benefits of utilizing an induced flow exhaust fan is to dilute the contaminated air at the outlet as well as increase outlet volume which accelerates the discharge air increasing plume height without a tall stack.
