PRESSURE SWITCH W/ UNLOADER

The General Air Products Pressure Switch with Unloader is engineered for installation within dry pipe, preaction, or specialized fire protection air compressor assemblies. It automatically regulates compressor cut-in and cut-out thresholds to maintain consistent supervisory pressure levels. By governing system cycling, the unit ensures your compressor operates within intended design parameters to safeguard life safety assets.

This assembly satisfies stringent operational reliability demands governed under NFPA 13 and NFPA 25 standards for proper maintenance and monitoring of fire protection air supplies. The integrated unloader valve relieves head pressure during shutdown, reducing initial startup torque and preventing motor overloads during frequent cycling periods.

Key Features & Construction

• Corrosion-Resistant Build: Fabricated from durable materials tailored to withstand demanding industrial equipment environments.
• Integrated Unloader Valve: Vents trapped compressor head pressure upon shutdown to lower startup load and prevent motor strain.
• Adjustable Settings: Permits precise calibration of cut-in and cut-out pressure thresholds to match exact system requirements.
• Compact Profile: Installs directly onto standard air compressor configurations without requiring complex structural modifications.
• Electrical Integration: Connects with standard commercial voltage ranges utilized in typical fire protection compressor setups.
