Drawing   3D Model

Although the BV4000 was developed for large, sealed shipping containers, it can be used for any application that requires pressure and vacuum relief and a high flow rate. Just one provides enough air flow for an internal volume of 833 ft3. An aluminum shield is provided to prevent intrusion of water during spray-down as well as wind-driven sand, dust, and rain. Container pressure can also be manually equalized with the button in the center. A mounting nut is included for easy installation.
