Air Compressor Pressure Switch 220V | 4 Port Manifold | 30-120PSI Gauge

This air compressor pressure switch is a 220V to 240V pressure controller with a 4 port manifold, a piston type relief valve and a gauge, built to start and stop a small compressor pump as tank pressure moves between its set points. It works across a 0.05 to 1.2MPa operating range and passes up to 3000L/min through the valve body, so it suits direct drive and oil-free compressors on the workshop floor. Features and benefits: - Piston type valve with V-type sealing ring: seal is described as wear resistant and stable, for steady switching over time - Flow rate stated as 30% larger than a traditional diaphragm design: up to 3000L/min through the manifold - Overflow port in the valve body: pressure drops quickly and the release can be seen as it happens - Regulator knob included in the box for pressure regulation - Gauge scales in kg/cm2, kPa (BAR) and Lb/in2 (PSI), up to 180 on the PSI scale: read pressure in whichever unit you work in - Takes the original gas pressure gauge and the original venting valve: fits existing setups without extra changes - Small, light body that can be mounted reversed, vertical or horizontal: flexible fitting in tight compressor housings Applications: - Direct drive air compressors in the workshop - Oil-free silent compressors - Small belt conveyor air supply - Replacing a worn switch on a pump and tank set In the box: - 1 x air compressor pressure switch - 2 x pressure gauges - 1 x regulator knob - 2 x brass fittings - 1 x red safety valve - 2 x quick-connect fittings Note: This is a mains 220V to 240V device marked MAX 380V/220V. Isolate the compressor from the supply and release all tank pressure before fitting or adjusting, and have the wiring done by a competent person. A red release button sits on top of the housing.
