Air & Water Pressure Switches for Compressors & Pumps
Solid State Electric Motor Starter Switches for Industrial Applications
Many industries using air compressors and water pumps depend on equipment uptime to optimize efficiency. Stearns offers a line of electronic starting switches that deliver improved single-phase motor performance and reliability, even in harsh environments, thanks to high resistance to moisture, dust, vibrations and shock. Our industrial pressure switches also filter out electrical noise and are able to operate in areas susceptible to brownouts or low voltage.
Stearns SINPAC switches are designed to fit both new and legacy compressor and pump motors for seamless OEM integration, easy installation and simplified assembly. Replacing a mechanical or centrifugal switch with one of our solid-state switches helps keep compressors and pumps moving, with fewer moving parts.
Types of Switches for Commercial Compressors & Pumps
Stearns’ SINPAC switches are durable and ideal for applications involving single phase AC electric motors with consistent switching on and off of start circuits, such as those found in industrial air compressors and water pumps. Pressure switch types include:
- CV: Capacitor start, max 2-3HP motor, 40-50 Amps switch rating, 115V start circuit
- 2CV: Capacitor start, max 5HP motor, 50 Amps switch rating, 230V start circuit
- VR: Capacitor start & run, max 3HP motor, 50 Amps switch rating, 115V start circuit
- 2VR: Capacitor start & run, max 5HP motor, 50 Amps switch rating, 230V start circuit
- IR: Instant reverse capacitor start, max 2HP motor, 40 Amps switch rating, 115V start circuit
- IVR: Instant reverse capacitor start, max 3HP motor, 40 Amps switch rating, 115V start circuit
All SINPAC switches are accepted by motor manufacturers and UL recognized (file E71115).
