Potter PAAR-B Automatic Air Release

Minimize trapped air and protect your fire sprinkler piping, detectors and sensitive assets with the Potter PAAR-B automatic air release. This float-type air vent from Potter Electric Signal, LLC is designed to vent air during system fill and as air migrates over time—reducing corrosion at the air/water interface and improving vane-type waterflow detector response for more reliable fire monitoring. Engineered for real-world installations, the PAAR-B is UL Listed and FM Approved for automatic air release valve service on sprinkler branch lines and includes an integrated water-retention pan with a 1/2" NPT drain for safe discharge routing.

A secondary positive-stop shutoff valve prevents uncontrolled water loss; it features a visual trip indicator and a supervisory NC contact rated 24V AC/DC@2A for electronic supervision and easy integration into security, surveillance and building management systems. The single-use shutoff element simplifies maintenance while providing dependable fail-safe protection. Specify the Potter PAAR-B for commercial, data center and critical-security applications where reliable fire protection and uninterrupted monitoring are essential. Contact your supplier to add the PAAR-B to your next sprinkler system design or retrofit.
