Company: RectorSeal

Product: SureSeal^® Vent-Guard

Description: SureSeal Vent-Guard is a plumbing vent stack device for eliminating toxic sewer gas and odor egress and migration to nearby rooftop HVAC system outdoor air intakes. The Vent-Guard is available in three sizes designed to fit 2-, 3-, and 4-inch-diameter commercial building plumbing vent stacks and restaurant grease interceptor vents. The Vent-Guard introduces outdoor air via its sturdy, non-mechanical hinged flapper that automatically opens during vacuum occurrences caused by vent stack pressure imbalance events, such as toilet flushes. Otherwise, the flapper remains tightly sealed during a vent stack’s routine state of neutral pressure. The closed flapper eliminates heavier-than-air gas and odors from escaping the vent stack and traversing the roof where they can infiltrate nearby HVAC systems’ outdoor air intakes and potentially contaminate the building’s IAQ.
