Sealing & Canister Construction

Outer Canister: Thick cold-rolled steel anti-corrosion coated shell, pressure resistant against oil flow fluctuation during compressor load/unload cycles

Sealing Gasket: High temperature resistant NBR nitrile rubber ring, zero oil leakage under long-term thermal cycling

Internal Support: Perforated galvanized steel inner & outer support cages, anti-collapse media structure under oil pressure surges

Key Product Advantages

Critical protection for compressor core rotor & bearing components

This oil filter intercepts metal wear particles, carbon sludge, dust and oxidation impurities circulating within the lubrication circuit. It prevents abrasive scratches on male/female rotors, bearing wear and premature main engine breakdown, greatly extending the service life of expensive screw rotor assemblies.

Integrated safety bypass valve eliminates cold start failure risk

During winter cold startup, lubricant viscosity rises sharply and creates high flow resistance. The built-in 2.5 bar bypass valve opens automatically to guarantee uninterrupted oil supply to bearings, avoiding severe mechanical seizure damage.

High-capacity media with long service cycle and stable low pressure loss

Deep-pleated composite dual-layer media provides massive contaminant holding capacity, slowing pressure rise during full service cycle. Consistent low oil flow resistance reduces auxiliary oil pump power consumption and cuts overall compressor energy costs.

Heat & oil resistant full metal spin-on robust design

Thick steel canister withstands frequent pressure fluctuations from compressor loading/unloading cycles; NBR gasket maintains sealing integrity under sustained high oil temperature without hardening or cracking, eliminating external oil leakage failures.

Application Scope

Automotive component manufacturing workshops, metal cutting & welding factories, food & beverage packaging pneumatic lines, plastic injection molding plants, textile factory compressed air supply, small-medium pharmaceutical production air systems, general machinery processing pneumatic equipment.
