Arrow Pneumatics ASP-12BV Breather Vent Assembly

Arrow Pneumatics ASP-12BV is a bronze, sintered-bronze breather vent with a 1-1/2-inch connection designed to equalize pressure inside closed pneumatic housings by exchanging air with the surrounding atmosphere, preventing unexpected pressure or vacuum changes in sealed chambers. Identified in Arrow’s line as the ASP-12BV Bronze Pneumatic Breather Vent, this part is specified for a 1-1/2" size and is commonly offered with 1-1/2" NPT threading in distributor listings. It carries a 100 psi inlet pressure rating, making it suitable for venting air from gearboxes, housings, and other enclosed pneumatic components that require controlled venting. The vent’s bronze, sintered-bronze construction and its place in Arrow’s premium breather vent lineup are confirmed by multiple catalogs and distributors, including Grainger and Pneumatic Plus, which list the ASP-12BV in their Arrow Pneumatics offerings. This part is widely available through major industrial suppliers, reflecting its role in maintaining pressure balance in enclosed pneumatic systems.
