These switches manage cut-in and cut-out pressure settings to maintain safe, consistent operation. We offer a variety of PSI ranges, port configurations, and voltage ratings to fit most compressor models, including many models from Square D, Worldwide Electric and Lefoo.
[pdf] If the capacity of the air compressor is really too low, check the following: Check differential pressure over oil separator. Replace separator when necessary. Check and replace compressed air filters (if installed). Compressor does not unload. Check if pressure switch is correctly set and working.
[pdf] This test is performed to ensure that there are no leaks in the piping, compressor, or other pressure containing parts of the package. All openings in the completed compressor package are plugged and the unit is pressurized with nitrogen to 350 psig.
