Morrison Bros. 245F Series Flanged Emergency Vent w/ Flange Adapter, Gasket & Hardware (MO245F0408AK,MO245F0608AK,MO245F0808AK,MO245F1008AK)
Morisson's Model 245F is a lightweight, spring-loaded emergency vent (pressure relief only) used on aboveground storage tanks, as a code requirement, to help prevent the tank from becoming over-pressurized and possibly rupturing if ever exposed to fire. This vent must be used in conjunction with a "normal vent". Correct application of this vent requires proper vent size and selection for the tank system in order to meet the specific venting capacity. Includes flange adapter, gasket and nuts/bolts.
Note: Emergency vent should be set higher than the normal vent so the normal vent operates first.
