Air-Oil Separator RN27526

RN27526 is a high-efficiency built-in flange-type air/oil separator core designed specifically for medium and large industrial screw air compressors[1]. As a core maintenance consumable in the air circuit system of air compressors, it undertakes the critical task of thoroughly separating compressed air from lubricating oil mist, which directly determines the quality of the final compressed air and the operating efficiency of the entire pneumatic system.

Core Working Principle

During the operation of the screw air compressor, a large amount of lubricating oil is injected into the airend for cooling and sealing, forming a high-density oil-gas mixture. RN27526 adopts advanced coalescing technology:

1. Impingement and Interception: As the oil-gas mixture passes through the specially made multi-layer ultra-fine glass fiber filter media, tiny oil mist particles (as small as 0.3 microns) are intercepted by the filter screen[1].

2. Coalescence and Enlargement: Tiny oil droplets collide with each other inside the fiber layer and coalesce into larger oil droplets.

3. Gravity Oil Return: The coalesced liquid oil accumulates at the bottom of the filter element under gravity, and is drawn back to the airend through the oil return pipe of the air compressor for recycling, while clean compressed air is discharged through the air outlet.
