Now--Available for the First Time—a Breakthrough in Ultra-Low Pressure Switch Design That Helps Avert Normal Contact Resistance, Set Point Instability and Leakage Problems.

Traditional ultra-low pressure, vacuum and differential switches will inevitably wear down in low pressure environments, causing contact erosion, loose terminals, switch instability and leakage. (read more)

LF19 pressure switches can also be used to regulate the tank pressure between two preset values on one phase electrically driven air compressors. They are available with an unloader valve, which prevents compressors from starting under load, and it is available with an On-Off knob for manual cut off the compressor. (read more)

The LF18 pressure switches are used to regulate the tank pressure between two preset values on 3 phase electrically driven air compressors. They are available with an unloader valve, which prevents compressors from starting under load, and it is available with an On-Off knob for manual cut off the compressor. (read more)
