Fume Hood Inline Exhaust Fan


The AFE fume hood inline exhaust fan is an ideal choice for successfully removing undesirable fumes and gases from laboratory hoods, kitchen hoods, process operations, foundry operations and many other applications. The AFE is not intended as a substitute for proper pollution control equipment, but rather a means to exhaust low concentrations of potentially toxic fumes out of and away from occupied spaces.

The AFE employs a specially designed non-overloading airfoil impeller. In a tubular centrifugal fan, the air turns 90° after leaving the impeller. Aerovent’s unique impeller design with open back plate (patent #5,171,128) allows this turn to be made with a minimum of turbulence loss. Also, the extra wide blade design helps deliver a larger air volume for a given impeller diameter. The AFE impeller improves overall efficiency and reduces sound levels.
