Provides pressure and vacuum relief in applications that require vapors to be piped away in lieu of venting to the atmosphere. The pallets in the housing allow intake of air and release of vapors as the tank breathes normally. In the standard configuration, relieving vapors are piped away through a flanged connection one size larger than the inlet, providing greater flow capabilities. Same size outlet flange also available.
- Alternate diaphram materials.
- Mounting connections added to vacuum port.
- Manual or electronic indication of vent opening.
