Pressure Switch With Unloader Valve For Air Compressors

Regulate internal air compressor pressures and safeguard your motor with the General Air Products Pressure Switch with Unloader Valve. This component installs directly within your air compressor assembly to automatically control pressure buildup and vent excess air during shutoff cycles. Air maintenance devices and compressors operate in conjunction with dry pipe and preaction fire sprinkler systems to maintain necessary supervisory air pressures, satisfying strict system maintenance and reliability protocols.

Compliance is maintained directly through adherence to NFPA 13 and NFPA 25 standards for fire protection system operation. By automatically activating the compressor motor based on precise pressure thresholds, this unit prevents dangerous over-pressurization and reduces mechanical stress across industrial and contractor-grade applications.

• Integrated Unloader Valve: Combines pressure switching and unloader functions into a single streamlined unit to vent surplus air and reduce motor load.
• Durable Construction: Features a robust metal base paired with a protective black housing built to withstand demanding mechanical environments.
• Automatic Pressure Regulation: Controls motor activation based on set pressure points to prevent over-pressurization and mechanical wear.
• Compact Design: Utilizes a space-efficient form factor that simplifies installation and maintenance across compatible compressor models.

Always verify local Authority Having Jurisdiction (AHJ) requirements and consult manufacturer technical data sheets before beginning installation.
