The Automatic Air Release Float Vent (PAAR-B) by Potter Electric Signal is an essential component designed to enhance the performance and reliability of fire sprinkler systems in commercial and industrial buildings. This device automatically vents trapped air during system fill and operation, ensuring optimal water flow and system responsiveness when fire protection matters most.

• Material Construction: Made from durable, corrosion-resistant brass alloy with a stainless steel internal float and heat-resistant EPDM elastomer seals, resisting wear in pressurized, wet environments.
• Automatic Air Release Mechanism: Features a precision internal float that senses rising water levels to close the vent tightly, preventing water leakage while continuously releasing trapped air to maintain system integrity.
• Regulatory Compliance: Fully UL listed for automatic air vents in fire protection, FM approved, and meets NFPA 13 standards for reliable safety and performance in fire sprinkler systems.
• Compatibility and Installation: Designed for sprinkler systems operating up to 175 psi (12.1 bar) with a standard 1-inch NPT connection, allowing seamless installation without needing additional adapters.
• Maintenance Benefits: By efficiently expelling air pockets that cause corrosion and detection delays, it reduces false alarms, lowers maintenance frequency, and extends system lifespan.
• Optimized for Large-Scale Use: Engineered specifically for high-occupancy and commercial buildings, improving waterflow detector sensitivity and overall sprinkler response times.

By constantly removing trapped air, the PAAR-B supports earlier fire detection and reliable sprinkler activation, enhancing safety in complex fire protection setups. Its robust materials and proven design minimize corrosion and false alarms, helping facility managers maintain fire safety systems with reduced downtime and costs. This automatic air release vent ensures your fire sprinkler system operates at peak efficiency, providing peace of mind for building occupants and safety personnel alike.
