This filter provides medium-grade filtration (F9) with an efficiency of 99.9%, ensuring reliable protection for compressor heads and bearings. Constructed with fiberglass filter media and a durable shell (plastic or metal depending on housing), it is engineered for industrial environments.
The filter is designed for Kaishan Boreas BK series compressors, including BK11 (11 kW) and BK15 (15 kW) units.
For optimal performance, replacement is recommended every 2,000–2,500 working hours, preventing dirt buildup that can damage the air end of the compressor.
