Core Filtration Functions:
1. High-precision depth filtration protecting rotor bearings
Micron-grade glass fiber filtration layers capture metal wear particles, pipeline welding slag, and system carbon deposits; this prevents wear and scoring on screw meshing surfaces and bearings, significantly extending the interval between major compressor overhauls.
2. Low initial pressure drop ensuring stable oil supply
Multi-layer gradient filter media offer low flow resistance, ensuring no drop in oil pressure during no-load operation; the pressure drop rises gradually as the element clogs, allowing the unit’s sensors to provide early warnings and prevent insufficient oil supply.
3. High contaminant holding capacity for extended service intervals
Pleated filter media provide a large effective filtration area; under standard 24-hour industrial operation, the filter requires replacement only every 8,000 hours, reducing the frequency of maintenance-related downtime.
4. All-metal pressure-resistant housing suitable for high-pressure oil circuits
The seamless steel tube body withstands internal oil pressure surges and eliminates the risk of cracking or leakage associated with plastic components, making it suitable for high-temperature, full-load operating conditions.
5. Integrated spin-on design for easy installation and removal
An all-in-one canister assembly eliminates the need to disassemble the filter element; maintenance involves a simple spin-on replacement that can be quickly performed by a single person.

Core Product Functions:
1. Precision Filtration of Refrigeration Oil (Core Function)
Oil supplied by the pump passes through a primary internal filter to remove solid impurities, serving as the fundamental protective component for the screw compressor unit.
2. Stable Oil Supply Pressure Differential; Prevention of Shutdowns Due to Oil Pressure Protection
A low-flow-resistance design ensures smooth oil circulation; as the filter element clogs and the pressure differential rises, the unit’s main controller triggers an oil filter blockage warning, allowing for timely replacement.
3. Prevention of Wear and Seizure of Screw Rotors and Bearings
Filters out metal debris and prevents hard particles from scratching meshing surfaces or bearings, thereby reducing the risk of compressor seizure and motor burnout.
4. Protection of Oil Coolers and Electronic Expansion Valve Passages
Clean refrigeration oil prevents clogging in oil cooler heat-exchange piping and the tiny flow channels of throttling valves, maintaining stable heat exchange and flow regulation.
5. Extension of Refrigeration Oil Service Life
Removes carbon deposits and impurities from the oil, slows down oil oxidation and degradation, and reduces the frequency of oil changes and the cost of consumables.
