This item is a side panel filter used on the Ingersoll Rand UP6-40 and UP6-50 rotary screw air compressors.
This is an OEM filter from Ingersoll Rand. Please contact us for confirmation this filter is designed for your rotary screw air compressor.
A rotary screw compressor panel pre-filter is used to filter the air prior to entering the compressor cabinet. This not only will help increase the cleanliness of the air compressor but it will lengthen the life of the air filter as well. Since the incoming air is now dual filtered, there is less of a chance that dust particles will be sent inside of the compression chamber, increasing the overall life of the compressor.
