The Vent 24 exhaust fan is designed to work with hydro¬gen gas detectors to protect battery charging rooms and other locations where motive and stationary batteries are present. The Vent 24 can also be used where there is a possibility of other flammable or toxic gases accumulating in confined spaces.
Vent 24 fans feature a sliding collar for easy installation in walls 1 1/2” to 8” in thickness. Fixed external rain louvers and motor driven internal louvers provide weather resistant venting. Energy costs decrease as a result of controlled exhaust fan operation rather than continuous fan operation.
Two models are available: 120 VAC, and 24 or 48 VDC. Op¬tionally the Vent 24 is available with the fan reversed for use as forced make-up air for the main vent fan.
