Standard Replacement Cycle: Replace after 4,000 operating hours or 12 months, whichever comes first; extendable to 8,000 hours in low-dust clean production environments

Differential Pressure Thresholds

Initial clean differential pressure: ≤0.012 MPa

Mandatory replacement alarm: ΔP ≥ 0.07 MPa

Sealing & Support Construction

End Caps: Reinforced corrosion-resistant PA polyamide

Key Product Advantages

It drastically reduces solid particle contamination load on DDp medium coalescer, QDp ultrafine coalescer and QD+ activated carbon cartridges, cutting replacement frequency and overall factory maintenance expenditure.

Ultra-large dust holding capacity for heavy-dust industrial workshops

Deep-pleated gradient glass fiber matrix provides massive dust storage volume, resisting rapid clogging in metal machining, forging, sandblasting and other dusty environments, minimizing production downtime caused by frequent filter replacement.

Ultra-low airflow resistance to reduce central compressor station power consumption

Large-area deep-fold filter media optimizes internal air channels, maintaining stable low pressure drop under 24/7 full-load continuous large-volume operation, effectively cutting extra power draw of large air compressor units and long-term electricity costs.

Hydrolysis & abrasion resistant media without fiber shedding

Hydrolysis-proof borosilicate glass fiber matched with stainless steel support cage prevents fiber shedding under long-term humid high-flow compressed air impact, avoiding secondary pipeline contamination to downstream coalescing media, precision pneumatic valves and spraying equipment.

Standard Atlas Copco bayonet quick-swap design without full housing disassembly

Working Principle

Raw unpurified compressed air flows outside-in through the filter cartridge:

Air first passes through outer thick blue non-woven foam to trap large coarse solid particles;

All solid particles larger than 3μm are captured and stored inside gradient glass fiber media;

Application Industries

Large metal machining workshops, heavy metal forging plants, sandblasting workshops, textile printing factories, large packaging printing equipment, medium & large factory centralized air compressor stations, construction machinery air supply systems, full-automatic large pneumatic automation production lines, low-demand food packaging equipment.
