Enclosure Breathers

Bison can install enclosure breathers for applications such as battery enclosures, which require high levels of protection from dust and water, in addition to a need to vent potential build-up of vapors or gases. These breathers for NEMA 4X enclosures stop the entry of water (both rain and hose down) while allowing ventilation of gases. These NEMA rated electrical enclosures remaining UL certified to NEMA 4X in Class 1, Div 1 & 2, Groups B, C and D environments.
