Products Description
1625703600 – Second-Stage Fine Coalescer for GA11–30 Screw Compressors
This component operates in the secondary fine filtration phase of the oil-air separation circuit on GA11–30 small to mid-power screw compressors.
Key Roles:
Micron-Level Capture & Coalescence: Mist droplets exceeding 0.1 μm are trapped in the ultra-fine glass fiber matrix and merged into larger drops. These drops descend to the cartridge base and are drawn back into the lubrication circuit through the return pipe.
Exhaust Purity Regulation: Holds oil carryover steadily at ≤ 3 ppm, ensuring the discharged air meets the intake criteria of downstream treatment systems in small and medium-power setups.
Safeguarding Downstream Assets: Shields refrigerated dryers, fine filters, and pneumatic end-devices from oil mist contamination.
Installation & Operation:
Housed within the oil reservoir of GA11–30 units. Following initial separation, the mist-laden airflow permeates the coalescing glass fiber media, where mist is aggregated and recovered, allowing purified air to exit via the central port.

FAQ
The functionality of the 2901196300 is delivered by the filter element within the kit, operating on the principle of coalescence separation:
Core Functions:
Oil Mist Inflow: Compressed air, after primary separation and carrying fine oil mist, enters the filter element.
Coalescence and Interception: Oil mist particles are captured on the surface of the ultra-fine glass fiber layer and coalesce into larger droplets; particles of ≤0.1 μm are effectively controlled.
Droplet Settling and Recovery: The coalesced droplets settle to the bottom of the element under gravity and are returned to the lubrication system via the oil return line.
Clean Air Output: Residual oil content is maintained at 3–6 ppm and discharged through the central outlet.
Installation Steps:
Shutdown and Depressurization: Turn off the compressor, disconnect the power supply, and release system pressure.
Removal of Old Kit: Open the oil separator tank, take out the old filter element, and record the position and quantity of the O-rings.
Internal Cleaning: Remove residual contaminants from the inner wall of the oil separator tank and the flange sealing surface.
Oil Return Pipe Inspection: Confirm that the oil return pipe is unobstructed and can reach the bottom of the new filter element.
Installation of New Element: Verify that the flange dimensions match, replace all O-rings, and install the element in the correct orientation.
Trial Run: Start the compressor, check for leaks, and observe the differential pressure indicator.
