Industrial ASP-4BV Breather Vent

The Arrow Pneumatics ASP-4BV 1/2 in NPT Breather Vent is a bronze-bodied vent with a sintered bronze filtration element that enables air exchange between a sealed pneumatic housing and the atmosphere while preventing particulate ingress. It provides 1/2 in NPT male inlet and 1/2 in NPT outlet connections, and its compact form measures a 7/8 in length with a 7/8 in outside diameter for tight-space installations. The vent is rated for up to 150 psi maximum operating pressure and uses a 40 micron filter to balance airflow with effective filtration. It operates across a wide temperature range from 35°F to 300°F, making it suitable for venting gearboxes, sealed housings, and other closed pneumatic components that require controlled venting without allowing contaminants in.
