Pneumatic Actuated Smoke Vent for High-Hazard Conditions


Developed by Babcock-Davis in collaboration with Jacobs Engineering, the pneumatic actuated smoke vent provides a UL 793 listed smoke vent that operates in a Class 1, Division 2 hazardous location. Justin Winterhalter, Regional Sales Manager, explains, "The challenge was to avoid any electronic component which may create sparks and possibly ignite the atmosphere causing a fire or explosion."

"The pneumatic actuated smoke vent uses a pressurized air system that can be set-up to open the vent automatically with a loss, or activation, of air pressure." explains Eric Wong, Babcock-Davis Product Engineer. "To facilitate the ease of installation air hose connections are quick-connect couplings on the exterior of the smoke vent curb."

The pneumatic actuated smoke vent maintains its UL 793 listing and labeling, and still includes fusible melt out links and manual pull handles.
