Envirosafe™ Above-Ground Fuel Systems carries a full line of fuel tank vents for above ground fuel tanks and other bulk fueling systems.We carry fuel updraft vents for the dispensing of a variety of fuels including gas, oil, methanol, diesel, and alternative fuels.
244 Series Emergency Vent
Emergency vent (pressure relief only) used on aboveground storage tanks, as a code requirement that helps prevent the tanks from becoming over-pressurized and rupturing if exposed to fire. UL listed except for 2″.
The 244 emergency vent consists of a body and a black powder coated cover (2″ not powder coated) that moves up and down on a center rod. Interior pressure of the tank forces the cover to elevate off the vent seat, allowing heated air to escape. The center rod guides the movement. When pressure falls, gravity forces the cover back down onto seat and the vent is automatically reset.
Code Compliance
When correctly sized for the tank, this vent will meet to the requirements of NFPA 30, 30A, UL 142, UL 2244, API 2000, and PEI
