Robust structure for industrial harsh conditions
There are numerous types of pressure switches for air compressors that come on
the market. Picking the right air compressor cut off switch depending on what
the air compressing system is. A new pressure switch is usually more precise
than repairing an old one, while adjustable digital pressure switches give you
more convenience when using them.

Intelligent air compressor pressure switches made by LEFOO pressure control are
instruments of pressure measurement, display, and control. The air compressor
cut-in and cut-off switch can automatically control the relay output according
to the pressure in the tubing. Compared with the mechanical switch, it has the
characteristics of simple operation, clear display, anti-vibration, and high
control accuracy.

When the compressor is plugged into the air compressor system, the motor starts
and the air compressor begins to pressurize. When the specified system pressure
is reached, a relay will control the electrical contacts apart, breaking the
circuit and stopping the motor. As air is used and tank pressure drops to a
specified ‘cut-in’ setting (approximately 30 PSI below the ‘cut-off’
setting) the relay contacts close and the motor starts again. The cycle
continues as long as the air compressor is in use.

LEFOO provide 300 gpd pump, differential air pressure sensor, differential
pressure sensor, peristaltic pump, etc. Contact us to know more.
