The AirTAC GFR600C20LJC1WT AirTAC Filter Regulator NPT3/4 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 GFR600C20LJC1WT is an AirTAC GFR-series filter regulator: filtration and pressure regulation combined in one body, removing water and particulate from compressed air and setting a stable downstream pressure. This size 600 unit is built with a 3/4 in NPT thread, a 5 um filter element (code W, against the 40 um standard), a differential-pressure drain and a round pressure gauge scaled in MPa. It is the low-pressure regulator type, and on size 600 units the bowl is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options across drain type, 40 um or 5 um filtration, gauge style and scale, G and NPT threads, brackets and a reverse/check valve. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm sizing and any datasheet figure against your application before you order.

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 and regulating the air fed to a workshop press cylinder, where the low-pressure regulator type lets the line run at a reduced set pressure and the 5 um element protects the valve from fine particulate.
A point-of-use filter regulator ahead of the actuators on a carton-sealing or filling line, draining condensed water automatically via the differential-pressure bowl drain and holding a steady supply pressure through shift changes.
Mounting in the air preparation stack of a CNC or assembly machine, filtering and regulating the supply to directional valves and air cylinders, with the MPa-scaled round gauge giving a clear set-point readout at the panel.
Every choice in this code is decodable: size 200/300/400/600 sets the port and flow step (here 3/4 in NPT, the largest size in the family, for lines with heavier air demand); drain is differential-pressure as standard, with automatic (A) and manual (M) available; filtration is 40 um standard or 5 um with W, which is what this unit carries; gauges are embedded square or external round, scaled in MPa, psi or bar (this unit: round, MPa); thread is PT as standard with G and NPT to order (here NPT); and brackets are optional, this unit shipping without one (code J). This is also the low-pressure regulator type (L); its exact regulation range is not published in the material we hold, so please confirm it with us. Because flow is published as curves rather than a single rating, ask us to check the curve for this size against your application before ordering.
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 the GFR series as curves, not as a single rated number, so we do not quote a l/min or SCFM figure. Send us your application details and we will confirm the flow curve and sizing for this 3/4 in, size 600 unit on request before you order.
W is the filter-grade code: this unit carries a 5 um element instead of the 40 um standard, giving finer protection for downstream valves and cylinders. The rest of the code decodes as size 600, 3/4 in NPT thread, low-pressure regulator type, differential-pressure drain, round MPa gauge, and no bracket or reverse/check valve.
