The AirTAC GFR600C25LJF3WT AirTAC Filter Regulator 1 in NPT 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 AirTAC GFR600C25LJF3WT is a size 600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is built around a 1 in NPT port for main-air and high-flow branch lines, a 5 um filter element (code W) for finer cleanliness than the standard 40 um grade, and a differential-pressure drain that bleeds accumulated condensate automatically as the pressure differential across the bowl rises. The regulator is the low-pressure type, and the unit carries a square gauge reading in bar. The aluminium alloy bowl is standard at size 600, and no mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with a choice of ports, PT, G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um elements, gauge scale options and bracket variants. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application 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.

Installed on a 1 in drop feeding a bottling hall's ring main, it strips water and fine dirt from the compressed air and holds a reduced, low set pressure for the hall's pneumatic supply.
Feeding the directional valves of a weld-fixture clamp circuit, the 5 um element protects spool clearances while the regulator holds the low clamping pressure the fixture designer specified.
Mounted ahead of the conveyor stop-and-lift cylinders on a carton packaging line, it removes condensate carried in from the compressor room and keeps actuator pressure steady at a low setting.
Step up through sizes 200, 300, 400 and 600 against the flow your line needs; this size 600 unit with its 1 in NPT port sits at the top of the range for main-air duty. Choose the drain to match maintenance access: differential-pressure (as here) needs no daily attention, automatic drains continuously, and manual drain suits attended installations. Pick the 5 um element (this code) when downstream valves and instruments need cleaner air than the 40 um standard, and choose the gauge scale - MPa, psi or bar - to suit your operators; this unit carries a square gauge in bar. Thread is NPT here, with PT and G available to order, and the J code means no mounting bracket is supplied. Note this is the low-pressure regulator type; its set-pressure range is not published in the same way as the standard type, so confirm it with us before ordering. Flow is published as curves, not a single rating, so send us your application and we will confirm sizing against the datasheet 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 the GFR series as curves rather than a single rated figure, so we do not quote one number. Send us your line pressure, set pressure and expected air demand, and we will confirm the sizing from the datasheet on request before you order.
The W in the code selects the 5 um filter element instead of the 40 um standard, giving finer protection for downstream valves and instruments. The F3 code fits the square gauge with the bar scale; MPa and psi scales are available on other codes if your plant reads differently.
