High-Dust Environments
In dusty operating conditions, this filter prevents abrasive particles from circulating in the compressor oil, extending airend life. The 10-micron impregnated paper media traps fine contaminants, ensuring clean oil reaches bearings and rotors even in challenging environments.
Continuous-Duty Operation
For compressors running 24/7, the robust element maintains integrity under constant flow. The high-quality media resists channeling and provides consistent filtration throughout the service interval, minimising the risk of unscheduled downtime.
Maintenance Scheduling Optimisation
The integrated bypass valve protects against oil starvation during cold starts or if the filter becomes loaded, allowing planned replacement instead of emergency swaps. This helps maintenance teams stick to predictive schedules and avoid unplanned interruptions.
Multi-Brand Fleet Consolidation
With cross-compatibility across many compressor brands, a single part number can replace multiple branded filters. This simplifies stock keeping, reduces ordering errors, and lowers inventory costs for fleets that include Dalgakiran, Almig, Compair-Demag, Ingersoll and others.
Check your existing filter's thread, diameter and height. This element requires a UN 1.1/2-inch female bottom thread, an outer diameter of approximately 137 mm, and a total height of 305 mm. Compare these measurements with your machine's specifications or contact our support team with your compressor model.
The filter is rated at 10 microns, using impregnated paper media. It captures fine particles from the oil, protecting internal components from premature wear and maintaining lubrication efficiency.
Total height is 305 mm, outer diameter is 137 mm, and the thread is a UN 1.1/2-inch female bottom type. The bypass valve opens at 1.75 bar, and the burst pressure is 23 bar.
This is an aftermarket product manufactured to the original dimensions and ratings. It provides comparable filtration and durability at a lower cost. It is not a genuine OEM part, but it directly replaces filters from brands like Compair-Demag, Mann-Filter and others.
The filter can be removed and installed by hand or with a strap wrench. After draining the oil, spin off the old element, lubricate the new seal with fresh oil, and tighten until the gasket contacts the base, then turn an additional half to three-quarter turn. Always follow the compressor manufacturer's service instructions.
Spare Part Mart offers worldwide shipping with tracking. This oil filter is covered by a 30-day money-back guarantee and a price-beat guarantee.
