Continuous-Duty Industrial Compressors
In manufacturing plants where compressors run 24/7, this filter ensures consistent oil cleanliness, reducing wear and extending service intervals. Its 2.5 bar bypass valve protects the engine during cold starts or filter clogging.
Dusty Construction Environments
For portable compressors used on construction sites, this filter's robust construction traps airborne contaminants effectively, preventing oil degradation and maintaining compressor efficiency even in harsh conditions.
Fleet Maintenance Consolidation
Fleet operators with mixed Compair-Demag and Gardner Denver equipment can standardise on one filter part number, simplifying inventory management and reducing the risk of fitting the wrong filter.
Remote or Harsh Climate Operations
In remote mining or oilfield applications where filter changes are infrequent, this filter's high dirt-holding capacity supports extended oil change intervals, reducing downtime and logistics costs.
This filter is verified to fit Compair-Demag models L 29, L 23, L 29 RS, and L 23 RS. It also fits Gardner Denver equipment. Check your compressor's model number against this list or measure your existing filter's thread (UNF 1 inch female bottom, 12 TPI) and dimensions (96 mm OD, 214 mm height).
This filter is a full-flow oil filter with a bypass valve opening pressure of 2.5 bar. While the exact micron rating is not specified, it is designed to the original dimensions and ratings for the listed Compair-Demag and Gardner Denver compressors.
It has a UNF 1-inch female bottom thread with 12 threads per inch. The outer diameter is 96 mm and the body height is 214 mm. Ensure your filter head accepts this thread configuration.
This is an aftermarket replacement filter, not a genuine OEM part. It is built to match the specifications of the original filters from Compair-Demag and Gardner Denver, offering a cost-effective alternative without compromising fit or function.
Installation is straightforward: spin the filter onto the filter head hand-tight, then tighten an additional 3/4 turn. Replacement intervals vary by operating conditions; always follow your compressor manufacturer's maintenance schedule.
