Dexon vent fans are intended to provide continuous positive pressure ventilation in climates NOT REQUIRING TEMPERING of the supply air.

Vent Fans are designed to run continuously at a preset idle speed providing constant low flow positive pressure safety ventilation to pumping station wet wells, dry wells, buildings, vaults and chambers for the safety of the operator and to provide a less corrosive environment for equipment. When required the Vent Fan can be switched to full fan speed to purge/flush the area prior to entering a confined space.

PLEASE NOTE: Vent fans are suitable for locations not requiring tempered air. It is not Dexon’s responsibility to determine if preheated air is required. Dexon will not be liable for any personal injuries, equipment or property damage caused by inappropriate installation or operation.
