Aerovent Drum Vent with filter and one extra replacement filter, 2" bung opening.

Provide emergency pressure venting in the event of a fire to avoid drum failure and catastrophic consequences. All safety drum vents automatically relieve pressure between 3 and 8 psi (30 to 55kPa) and include a flame arrester to absorb and safely dissipate heat. Valve within the vent is tested to allow 61 cubic inch (1-L) of water through a 3/8-in (9.5-mm) pipe nipple in less than 6 seconds for vacuum relief during drum dispensing operations. Vacuum relief permits smooth liquid flow and prevents possible drum collapse and leakage. Vacuum relief is automatic on vertically-installed vents and manual on horizontally-installed vents.

Fits a 2-in (51-mm) vertically-stored drum and has the same protection features of auto venting, auto vacuum relief, and a flame arrester as found in Justrite’s traditional safety vents—with the addition of a replaceable filter to control fugitive emissions. Brass body with an activated carbon filter adsorbs vapors and captures VOCs to keep them from escaping into the atmosphere during the exhale cycle. Use replacement filters when filter reaches full capacity or odors are present (approximately 90-120 days).
