Key Performance Advantages of the Filter Element
1. Gradient fiberglass depth filtration for precision protection of bearings and rotors
Featuring a multi-layer fiberglass gradient structure, the filter captures coarse impurities in the outer layers and fine particles in the inner layers. It effectively isolates wear debris from screw-star wheel and bearing interfaces, preventing scoring on meshing surfaces and compressor seizure that would necessitate a major overhaul.
2. Low initial pressure drop ensuring stable, consistent oil supply
Fiberglass media offer significantly lower flow resistance than metal mesh, ensuring stable oil pressure during no-load operation in new units. As the filter clogs, the pressure drop rises gradually; the unit’s pressure sensor provides early warning, preventing sudden high-temperature shutdowns caused by insufficient oil supply.
3. High contaminant holding capacity extends maintenance intervals
Utilizing a high-density pleated design to maximize effective filtration area, the filter supports 8,000 hours of operation in standard 24-hour continuous industrial units, thereby reducing the frequency of maintenance shutdowns.
4. Resistant to oil and refrigerant corrosion; no swelling or leakage
The fiberglass media, epoxy adhesive, and sealing rings do not react chemically with POE refrigeration oil or high-pressure refrigerants, ensuring no media shedding or seal leakage during long-term, high-temperature operation.

Product failure symptoms:
1. Oil filter blockage alarm; frequent compressor load limiting/capacity reduction
Severe accumulation of contaminants on the filter media causes the oil circuit pressure differential to exceed limits; the main controller restricts compressor loading, resulting in a significant drop in cooling capacity.
2. Insufficient oil supply; persistently high oil temperature leading to high-temperature protection shutdown
Reduced flow area in the oil circuit leads to inadequate bearing lubrication and frictional heating, causing rapid carbonization and degradation of the refrigeration oil.
3. Abnormal noise and accelerated wear of screw rotors and bearings
Filter element damage allows metal debris to enter the compressor block, scoring the meshing surfaces and increasing operating noise; severe cases result in rotor seizure.
4. Oil cooler blockage; consistently high condensing pressure
Impurities enter the narrow heat-exchange channels of the oil cooler with the oil, reducing heat-exchange efficiency and causing frequent high-pressure unloading.
5. Refrigeration oil leakage at flanges; system low-oil-level warning
Failure to replace O-rings leads to seal failure and oil leakage; insufficient oil triggers a low-pressure protection shutdown.
