Featuring a NEMA type 1 indoor enclosure, it has a built-in unloader valve and is rated for applications at 100 PSIG cut-in and 135 PSIG cut-out. Keeps Air Pressure Consistent and Reliable The pressure switch for your Ingersoll Rand air compressor measures the pressure inside your air tank and helps the machine maintain proper pressure levels as you work. When the pressure switch wears down or becomes faulty due to amp fluctuation, the operating pressure band can be affected leading to short cycling and sub-optimal performance. This Ingersoll Rand replacement pressure switch helps address these issues.
