In restaurant applications, GSV grease fans are used to vent broilers, BBQ, Pizza Ovens, fryers and other cooking appliances. With direct drive and variable speed they offer great energy savings and savings on operations and maintenance as there are not belts that can break.

In residential applications, GSV and BESF can vent kitchen hoods and pizza ovens. They can be used as “remote fans” that eliminate ventilation and motor noise in a kitchen while still providing maximum ventilation. The fans have variable speed and can be interlocked with most kitchen hoods that have variable speed control ability.


ENERVEX's grease fan can be used with wood and gas fired BBQ’s, pizza ovens, fireplaces and more.

Common Accessories

Fan Speed Control

Included with RS Series Fans


ENERVEX Fan Speed Control FSC is used in conjunction with all single-phased ENERVEX chimney fans. The fan speed control is specially engineered to provide variable speed control of split-capacitor motors. This control is accomplished by reducing the line voltage to the motor thereby using only the energy required to maintain the desired volume of air flow (fan speed).
Notice: The RSV 400 and 450 are 3x200-240VAC and cannot be controlled with this kind of fan speed control
