Products Description
2906904500 – Oil Mist Separation for Oil-Free Centrifugal Compressors
The 2906904500 is installed along the oil mist discharge path of the gearbox/bearing lubrication system on oil-free centrifugal compressors, rather than in the main compressed air exhaust route.
Core Functions:
Gearbox Breather Mist Treatment: Although the compression chamber of an oil-free centrifugal compressor is lubricant-free, its gearbox and bearings still rely on oil. The trace amount of oil mist generated during operation is vented through the breather, and the 2906904500 is responsible for capturing and separating this aerosol, preventing its release into the atmosphere or downstream systems.
Class 1 Air Quality Maintenance: Through multi-stage coalescence, residual oil content is kept at an extremely low level (≤0.01 mg/m³ for replacement parts), satisfying the stringent ISO 8573-1 Class 1 requirements for oil-free compressed air.
Lubricant Recovery: The merged droplets flow back into the gearbox, minimizing oil loss.
Downstream Equipment Safeguarding: It prevents oil mist from contaminating dryers, precision filters, and end-use equipment-a factor that is especially critical in air-quality-sensitive industries such as electronics, pharmaceuticals, and power generation.
Installation and Operating Principle:
Mounted at the centrifugal compressor's head breather/oil mist vent. The mist-laden gas passes through the filter element, where fine droplets are captured by the glass fiber media and coalesced into larger drops that return by gravity, while purified gas is discharged from the element's inner core.
