Morrison Bros. 244 Series 10 in. Flanged Emergency Vents – 2 1/2 oz/sq inch

Description

Emergency vents are installed on aboveground storage tanks as a code requirement. Emergency vents provide high capacity pressure relief if the tank is exposed to fire. When the internal tank pressure reaches the opening pressure of the vent, the weighted cover moves up on the center pin allowing air to escape. When the internal tank pressure falls, the cover automatically lowers back onto the body and is automatically reset.CFH = Cubic Feet Per Hour @ 2.5 PSIFeaturesAutomatically resets after openingDurable powder coated cast iron coversFlanged mounting connectionCARB EVR modelsCertified CFH flow capacitiesTheft deterrent screens availableConstruction Details:Body: AluminumCover: Powder coated cast ironO-Ring: Viton AScreen: 3 mesh stainless steelShipping Dimensions: 32.75 in. 24 in. 24 in.CertificationsWhen properly sized for the tank, this vent will conform to the following requirements:NFPA 3030AUL 142ULC S601API 2000IFCPEI RP200California Air Resources Board Phase I AST EVRVenting GuideVenting Guide (PDF Download)
