38471611 is a pressure switch conversion kit that replaces part number 56288798 if you are running the Ingersoll Rand 2545E10-P premium package compressor. This kit includes a replacement pressure switch, copper unloader tube, and pressure gauge.
Please note 38471611 will only work with the premium package 2545E10-P. The premium package IR compressor has a low oil level switch, air cooled aftercooler and centrifugal unloader so the compressor can run load/unload.
IR 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 56288798. This conversion kit provides all parts necessary to successfully convert your switch to the newer version. If instead you are running an Ingersoll Rand 2545 reciprocating compressor manufactured after 2010, you are able to purchase the 23474588 switch separately.
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.
