Dusty and Contaminated Environments
In cement plants, quarries, or foundries, airborne particulates can quickly degrade compressor oil. The 12 µm inorganic microfibre media captures a high percentage of these contaminants, protecting rotors and bearings from accelerated wear and reducing the frequency of unscheduled teardowns.
Continuous-Duty Operation
For compressors that run 24/7 in production facilities, consistent oil cleanliness is vital. The predictable bypass valve setting ensures oil always circulates, even under cold startup conditions, preventing starvation while still filtering effectively once the oil is at operating temperature.
Fleet Maintenance Consolidation
When a workshop services multiple compressor brands such as Kaeser and Compair-Demag, this filter replaces several OEM part numbers. Stocking a single aftermarket part simplifies inventory management and reduces the risk of ordering errors during routine servicing.
Preventive Maintenance Scheduling
Built with a sturdy collapse-resistant design, the filter maintains its integrity over the full service interval. Maintenance planners can rely on consistent performance to schedule oil and filter changes at fixed intervals, avoiding premature failures that lead to unplanned downtime.
If your machine appears in our verified compatibility list, the filter is a direct physical fit. The list covers specific models from Compair-Demag, Atlas, Chicago, Kaeser and Liutech. Please check the list carefully before ordering, as small variations in housing can occur even within a series.
The filter uses inorganic microfibre media to achieve an absolute filtration rating of 12 µm. This means it removes 99.9% of particles at that size and above, helping to maintain oil cleanliness and extend component life.
The filter has a UN 1.1/2-inch female bottom thread, an outer diameter of 137 mm, and a total height of 305 mm. These dimensions match the OEM design, so it spins directly onto the original mounting nipple without adaptors.
It is built to match OEM specifications for performance and durability, but it is not a genuine part. By avoiding the brand premium, we offer a cost-effective alternative that still delivers reliable filtration, making it a practical choice for non-warranty servicing.
No special tools are needed beyond a standard filter wrench. The spin-on design allows a straightforward replacement. Always pre-fill the new filter with fresh oil and lubricate the seal before installation, then tighten according to the manufacturer's instructions.
We provide worldwide shipping with tracking on every order. You are protected by a 30-day money-back guarantee if the product does not meet your expectations, and we also offer a price-beat guarantee against comparable aftermarket filters from other sellers.
