AUTOMATED PRECISION
The Kleinn Model 2131 is the heavy-duty "brain" of your air management. It takes absolute control, automatically signaling your compressor to kick ON when levels drop and OFF before exceeding safe limits. Engineered specifically for Kleinn 130 PSI Systems, it features a fully sealed housing and heavy-duty 12-gauge wires to thrive in the most extreme environments.
CRITICAL SAFETY ARCHITECTURE
Never compromise your rig. For maximum performance and total system protection, the 2131 MUST be paired with a 40-amp relay (Model 340) and a safety relief valve (Model 52155).
FAILSAFE DESIGN
This essential combination maintains strict pressure limits. If the switch eventually wears, the safety relief valve acts as your early warning system—Model 52155. If you hear the safety valve releasing repeated, high-pressure blasts of air, it is a definitive signal that your pressure switch has failed to cut off power that feeds the compressor. This alert tells you to immediately disconnect power to the compressor and replace the pressure switch before system damage occurs.
THE VERDICT: Engineered as the definitive 130 PSI control component for light-duty configurations, the Model 2131 eliminates pressure regulation guesswork while offering durable, weather-sealed structural protection.
This pressure switch is specifically designed for use with Kleinn 130 PSI systems. To ensure the perfect fit for your application, match the pressure switch to the 130 PSI Rating of your compressor.

SHIELD YOUR INVESTMENT. For maximum reliability and long-term performance, power this switch via an ignition source of 10+ amps. This MUST be used in conjunction with a 30/40 amp relay (like the Kleinn Model 340) to shield internal contacts from high-amperage surges during compressor startup. Proper isolation ensures consistent switching and hammers down on premature wear.
DON'T LET MOISTURE KILL YOUR SYSTEM. Pressure switches are high-performance wear items. To maximize longevity, use the Kleinn Snorkel Air Filter Relocation Kit included with all of our air compressors. By routing your air intake inside the vehicle cab, you significantly reduce moisture intake, stop internal tank corrosion dead, and effectively double the service life of your pressure switch.
