Hubbell 69JF9LY Air Compressor Pressure Switch 140-175 PSI Single Port with Unloader

The Hubbell 69JF9LY is a heavy-duty pressure switch designed for air compressor applications requiring reliable automatic control. This single-port switch features a preset pressure range with cut-in at 140 PSI and cut-out at 175 PSI, providing a 30-40 PSI differential for optimal compressor cycling.

Key Features:

• Pressure cut-in: 140 PSI, cut-out: 175 PSI
• 30-40 PSI pressure differential
• Single port configuration for simplified installation
• Integrated unloader valve for pressure relief during shutdown
• Manual on/off lever for convenient control
• Durable construction for industrial and commercial compressor systems

The built-in unloader mechanism releases trapped air pressure from the compressor pump head when the unit shuts off, reducing motor load during startup and extending equipment life. The manual on/off lever provides operator control for maintenance and safety shutdowns. Ideal for medium to large capacity air compressors in workshop, garage, and industrial applications.
