When servicing industrial rotary screw air compressors, finding the correct replacement filter shouldn’t require paying premium OEM markups or waiting weeks for authorized distributor shipments. A comprehensive filter cross reference guide allows plant managers and procurement teams to quickly identify high-quality aftermarket alternatives that match original factory specifications for fit, micron rating, and flow capacity.
Whether you are performing routine 2,000-hour servicing or overhauling an entire compressor room, use this quick reference table of popular replacement part numbers across major compressor brands.
Popular Air Compressor Filter Cross Reference Chart
Below are frequently requested OEM part numbers and their functional crossover equivalents across the “Big Three” filtration categories (Air Intake Filters, Spin-On Oil Filters, and Air-Oil Separators):

3 Critical Checks When Verifying Replacement Part Numbers
To ensure zero downtime and prevent air-end bypass, verify these three technical points before confirming your order:
- Thread Pitch & Gasket Dimensions: On spin-on oil filters and separators, verify the thread specification (e.g., M24x1.5, 1″-12 UNF, or 1-1/2″-16) and the outer/inner gasket diameters. A 1mm variance in gasket seating will cause immediate high-pressure oil leaks.
- Differential Pressure & Collapse Rating: Confirm that aftermarket oil filter canisters feature a minimum collapse pressure of 1.0–1.5 MPa to withstand cold-start pressure spikes.
- Flange Grounding on Air-Oil Separators: Ensure replacement flanged separators include built-in copper grounding staples or conductive gaskets to eliminate static electricity buildup inside the oil tank.
Summary
Maintaining an updated filter cross reference guide gives maintenance teams purchasing flexibility without sacrificing filtration performance. Always verify dimensional specs and media ratings to keep your rotary screw compressors running smoothly and cost-effectively.
