Key Product Advantages

Deep Capture of Invisible Submicron Oil Mist

Installed downstream of Grade P particulate prefilter, this Grade 4 element traps ultra-fine oil aerosols that standard coalescing media cannot capture. The outer white hydrophobic foam prevents liquid re-entrainment; coalesced oil and water drain rapidly to the filter bowl to deliver ultra-low residual oil compressed air.

Large Dirt Holding Capacity Extends Maintenance Cycles

Thick gradient glass fiber media provides massive oil & water storage volume, resisting rapid saturation under high humidity and high oil loading, reducing frequent replacement labor and spare parts costs for central air compressor stations.

Low Differential Pressure Energy-Saving Design

Deep-pleated glass fiber maximizes effective filtration area, maintaining stable low pressure drop under 24/7 full-load continuous operation to reduce compressor power consumption and long-term electricity expenses.

Hydrolysis & Abrasion Resistant, Fiber-Free Structure

Imported hydrophobic borosilicate glass fiber paired with stainless steel support mesh prevents fiber shedding under long-term humid compressed air operation, eliminating secondary pipeline contamination.

Working Principle

Dust-free pre-filtered compressed air flows outside-in through the filter cartridge:

Air passes through multi-layer gradient glass fiber, micro oil & water droplets collide and coalesce into large liquid drops;

Application Industries

Automotive high-gloss electrostatic painting lines, multi-line laser cutting equipment, pharmaceutical sterile cleanrooms, food aseptic filling & packaging, PCB & electronic component assembly, laboratory precision analytical instruments, precision pneumatic automation production lines.
