The 48958201 air filter element was most commonly used on the Ingersoll Rand RS30i, RS37i, RS30n and RS37N rotary screw compressors manufactured by IR. Note that this only works on the RS series and not the R series air compressors. If you are unsure of the exact air filter element, please contact our parts department for confirmation this will work in your compressor.
This Ingersoll air filter element should be changed every 4,000 hours. It is recommended to change the filter more often If your compressor is located in a dirty environment with lots of dust. Changing the air filter will prolong the life of your compressor by protecting the inlet and airend on the inside of the compressor. Proactively changing the air filter will also increase your energy efficiency by not restricting the inlet airflow going into the air compressor.
When changing the air filter element, it is also recommended to replace the oil coolant filter, separator element, and Ultra Coolant lubricant.
This is an OEM part manufactured by Ingersoll Rand. Many air filters shown online are aftermarket filters and are not rated to the same filtration specs as OEM.
