Key Product Advantages

Two-stage gradient coalescence drastically reduces oil consumption

Multi-density graded glass fiber captures submicron oil mist generated during screw compression. Coalesced liquid lubricant flows back to the compressor oil tank via central oil return tube, stabilizing downstream compressed air cleanliness and cutting lubricant refilling frequency.

Low initial differential pressure for energy efficiency

Deep-pleated large filtration area optimizes internal oil-gas flow passages. Pressure drop remains stable under 24/7 full-load continuous operation, avoiding extra motor load and higher power consumption caused by clogged separators.

Extra-large oil & sludge holding capacity for extended maintenance cycles

Thick gradient fiber matrix stores massive coalesced lubricant oil, carbon sludge and metal wear debris. It resists rapid clogging even with deteriorated high-temperature oil, ideal for non-stop heavy industrial production.

Heavy-duty anti-corrosion reinforced construction

Galvanized metal mesh and heat-resistant composite gaskets withstand long-term hot oil-gas mixed environments. Effectively prevent media rupture and fiber shedding to avoid secondary oil contamination of inline precision filters, laser cutting equipment and spray coating lines.

Working Principle

High-temperature high-pressure oil-gas mixture discharged from the screw airend penetrates the glass fiber media from outside to inside. 0.01μm oil mist particles collide and agglomerate into large liquid droplets on fiber surfaces. Oil droplets sink to the separator bottom by gravity and flow back to the lube oil tank through the central return pipe. Degreased clean compressed air is delivered to refrigerated air dryers and inline precision filter systems.
