Induced Flow Mixed Flow Exhaust Fan,
Belt Driven


The QIFE Induced Flow Mixed Flow 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 makeup air. This unit is commonly used in exhaust systems for universities, schools, hospitals, research facilities, laboratories, restaurants and wastewater treatment plants.

Induced flow exhaust fans dilute contaminated air at the outlet as well as increase the outlet volume of the fan. This accelerates the discharge air, increasing plume height without a tall stack.
