The AirTAC GFR600C20LNWT AirTAC Filter Regulator, NPT3/4, 5 um is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR600C20LNWT is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This configuration is built on the size 600 frame with a 3/4 in NPT port, a 5 um filter element (code W, against the 40 um standard), the series-default differential-pressure drain, and the low-pressure regulator type (L). No gauge is fitted (code N) and no reverse/check valve is fitted. The bowl on this size is aluminium alloy, maximum working pressure is 1.0 MPa (145 psi), the operating temperature range is -5 to 70 C (non-freezing), and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, plus drain, filter-grade, gauge, thread (PT standard; G and NPT as order options) and bracket choices. Flow for this size is published as curves rather than a single rating, and the exact setting range of the low-pressure type is not published, so ask us to confirm both against your application - datasheet figures on request.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Conditioning the 3/4 in main drop that feeds clamps and pneumatic actuators on an automotive stamping line, keeping condensed water and fine particulate out of downstream valves while holding a steady low set pressure.
Supplying air knives, blast nozzles and diverter cylinders on a food or carton packaging conveyor, where a 5 um element protects small orifices from water carryover and dust at a stable reduced pressure.
Feeding the fixture-clamping and part-ejection circuit of a CNC machining center, where the low-pressure regulator type suits circuits that work at reduced set points and the bracket allows clean panel-side mounting.
The decodable choices in this family are size and port (200 to 600, ports 1/8 in to 1 in - this model steps up to size 600 with a 3/4 in NPT port for larger supply lines), drain type (differential-pressure as here, automatic, or manual), filter grade (40 um standard or 5 um with W - the finer 5 um element is fitted here), gauge and scale (none on this code; embedded square or external round gauges with MPa, psi or bar scales exist in the series), thread (PT is the standard; G and NPT are order options - NPT here), and bracket (included on this code). The L suffix marks the low-pressure regulator type; its exact setting range is not published, so confirm your set point with us before ordering.
Flow is published as curves, not a single rating, so there is no one rated-flow figure to quote. Send us your required flow and line conditions and we will check the size 600 curve against the application before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this series as curves, not as a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Send us your required flow, working pressure and set point and we will confirm against the size 600 datasheet curve on request before you order.
The N in the code means no gauge is fitted, so the regulator is set without a supplied instrument. The GFR series offers an embedded square gauge or an external round gauge with MPa, psi or bar scales on regulator-equipped units - tell us the scale you want and we will confirm the matching order code and the low-pressure type setting range on request.
