49 305 55 121 is a high-efficiency built-in flange-mounted oil-gas separation cartridge specially designed , a global leader in filter manufacturing, for screw air compressors and vacuum pumps. Adopting the industry-leading depth coalescence filtration technology, it serves as a core component to guarantee compressed air quality, protect downstream gas-using equipment and reduce lubricating oil consumption.
Core Product Advantages
• Extremely low initial pressure drop (resistance): The unique folding or winding process greatly increases the effective filtration area. The filter element has very low resistance, which can directly reduce the energy consumption of the air compressor and help enterprises save electricity costs.
• Ultra-long service life: Under standard working conditions and normal operation of the air filter, the designed service life of this filter element can generally reach around 4000 hours.
• High-efficiency oil carryover prevention: With an extremely low oil carryover of 1–3 mg/m³, it can significantly cut the daily consumption of air compressor lubricating oil, extend oil service life, and reduce the maintenance load of downstream purification equipment (such as refrigerated dryers, adsorption dryers and precision filters).
Installation Notes
Power off and depressurize fully. Clean tank and flange, check gasket. Install element vertically, tighten bolts crosswise evenly. Adjust oil return tube, test run no-load, check leakage and DP.
Maintenance & Replacement
Monitor differential pressure, replace when DP rises. Check oil carry-over regularly. Use qualified compressor oil. Store dry, discard damaged element.
