Dusty Construction Sites
In environments with high airborne dust, such as construction sites, the 25 µm inorganic microfibre media captures fine particles, protecting the compressor from premature wear and extending service intervals.
Continuous-Duty Industrial Operations
For compressors running 24/7 in manufacturing plants, this filter's 12 bar working pressure and robust construction ensure consistent oil filtration, reducing downtime and maintenance frequency.
Fleet Maintenance Consolidation
Workshop managers servicing multiple Sullair models like BDS 7.5, BDS 15, and ES 6 can stock a single filter (this filter) to simplify inventory and reduce storage costs.
Remote or Mobile Compressor Applications
For portable Sullair units such as the TREK series, the filter's lightweight design (0.79 kg) and standard UN thread make field replacements quick and easy, minimising downtime in remote locations.
Check your compressor model against the verified list: this filter fits Sullair models including TREK 11, BDS 30 up to 2003, ES 8 Sullube, VS 16 30/40 HP, and many others. If your model is not listed, please contact us with your OEM part number for cross-reference.
The filter uses inorganic microfibre media with a filtration rating of 25 µm. This media provides high dirt-holding capacity and efficient particle capture for compressor oil.
The thread is UN 31/32" female bottom. Total height is 145 mm, outer diameter is 95.5 mm, and net weight is 0.79 kg. Ensure your housing accepts this thread size and orientation.
This is a high-quality aftermarket filter, not OEM. It is a direct replacement for filters from Baldwin, Delsa, Fai Filtri, Fleetguard, and others, built to match OEM specifications at a lower cost.
Installation is straightforward: unscrew the old filter, clean the mounting surface, apply a thin coat of oil to the new filter gasket, then hand-tighten the new filter until the gasket contacts the base, then tighten an additional 3/4 turn. Do not use a filter wrench for final tightening.
