The air-oil separator is the highest-value filter inside an oil-lubricated screw compressor. It coalesces oil mist out of the compressed air stream and returns it to the circuit, keeping oil carryover low and protecting downstream equipment.
Our separator elements use borosilicate fiberglass media with stainless steel support mesh, engineered for residual oil content of ≤ 3 ppm and a pressure-drop curve that stays flat over thousands of running hours. Send us the OEM part number printed on your current element — we match outer diameter, length, end-cap style, gasket and threads before quoting.
Every separator is produced against the OEM reference. Confirm these points with our engineer in one message.
| Item | Standard Range | Notes |
|---|---|---|
| Residual oil content | ≤ 3 ppm (w) | Tested per ISO 8573 method; lower on request |
| Initial pressure drop | Low ΔP design | Optimized pleat / wrap geometry per size |
| Media | Borosilicate fiberglass | Stainless steel support mesh inside & outside |
| End caps | Steel / aluminum, threaded or plain | Matched to OEM style |
| Gasket & seals | NBR standard; Viton® optional | For high-temperature or synthetic-oil duty |
| Dimensions | OD × length to OEM drawing | Confirmed before production; sample on request |
| Working conditions | Oil-lubricated screw compressors | Mineral or synthetic oils |
| Packing | PE sealed bag + foam + export carton | Palletized for sea freight |
Media and flow path engineered so pressure drop stays low from day one to replacement — energy you don't waste.
≤ 3 ppm residual oil protects dryers, valves and your customer's process air quality.
Diameter, length, thread and gasket matched to the original — drops straight in, no rework.
Same media, same process, same inspection for samples and volume orders. Dimensional check on every batch.
Standard references produced in 7–15 working days; samples possible faster. Direct factory communication.
Sealed bags, foam brackets and cartons that survive long sea freight. Full export documents provided.
Our engineers maintain cross-reference data across major compressor brands. Send your code — here is how the match works:
| You Send (OEM P/N) | We Confirm | You Receive |
|---|---|---|
| Part number on your filter label (photo is fine) | Dimensions · media · end-cap style · gasket | Quotation + drawing confirmation |
| Compressor brand & model (if no label) | Original separator specification | Matching replacement, element only or with housing |
| A used sample (if part is special) | Measured drawing for your approval | Custom-built separators to approved drawing |
Full brand-by-brand cross-reference tables are shared with quotations — including fitment notes for each machine model.
One WhatsApp message with your OEM code and quantity — the quotation lands within 24 hours on working days.
