Model PV-3 Spark Arresting Purge Vent Accessory

The Model PV-3 Purge Vent is a gravity operated enclosure pressure relieving device designed to relieve excess pressure inside a protected enclosure while preventing any sparks or burning material from escaping into a classified location. A required accessory for Model YZ103 purge units, the Model PV-3 will begin to open when enclosure pressure exceeds approximately 0.8” w.c. and will fully open once enclosure pressure exceeds approximately 1.5”. Model PV-3 is constructed of aluminum and stainless steel components providing corrosion protection from harsh environments. Being gravity operated, the Model PV-3 MUST be installed in a true vertical position for proper operation and is available in “T” (top mount) and “S” (side mount) configurations. The device attaches to the protected enclosure via a standard conduit hub and can alternately be remotely mounted (contact factory for details).
