Ingersoll Rand 38471561 Pressure Switch Conversion Kit for 2475 Premium Package Air Compressors

Ingersoll Rand (38471561) Pressure Switch Conversion Kit for 2475 Premium Package Air Compressors

38471561 is a pressure switch conversion kit that replaces pressure switch number 56288764 if you are running the Ingersoll Rand premium package 2475N5 or 2475N7.5 piston compressors. This kit includes a replacement pressure switch, copper unloader line, and pressure gauge.

Ingersoll Rand changed pressure switch manufacturers in approximately 2009. The on/off switch and unloader valve are now on the opposite side of the older version switch. The old pressure switch part number was 56288764. This conversion kit provides all necessary parts to successfully convert your switch to the newer version. If instead you are running an Ingersoll Rand reciprocating compressor manufactured after 2010, you are able to purchase the 23474653 switch separately.

Please note 38471561 will only work with the premium package 2475 piston compressors that have a model number of 2475N5-P and 2475N7.5-P.

The pressure switch turns the compressor on when it hits the lower pressure setpoint and turns the compressor off when the upper setpoint is reached. This is an OEM switch from Ingersoll Rand. Plenty of aftermarket switches are sold online, but many of them are not rated for the full load amp draw of the compressor and will cause pre-mature wear to the switch. The OEM switch from Ingersoll Rand is rated for a higher amp draw and is much heavier duty compared to others.

If you find your pressure switch is constantly leaking out of the unloader line, you should consider changing the 85582112 check valve instead.
