Vent 12
Protects life and property from hydrogen gas and other explosive or toxic atmospheres.

All our products are proudly made in the United States of America.


The Vent 12 exhaust fan is designed to work with hydrogen gas detectors to protect battery charging rooms and other locations where motive and stationary batteries are present.

The Vent 12 can also be used where there is a possibility of other flammable or toxic gases accumulating in confined spaces.

Vent 12 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. Optionally the Vent 12 is available with the fan reversed for use as forced make-up air for the main vent fan.
