The AirTAC GFR600C25ALJF2WK AirTAC Filter Regulator 1 in PT 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 GFR600C25ALJF2WK is an AirTAC GFR600 filter regulator: water and particulate removal plus pressure regulation in a single body. This configuration is the 600 size with a 1 in PT port, the 5 um filter element (code W), an automatic drain, and an aluminium alloy bowl, which is the standard bowl material at size 600. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Regulation is the low-pressure type, intended for circuits that run below standard line pressure; the exact set range is not published in the catalogue and we confirm it on request. A reverse (check) valve is fitted, an embedded square gauge with a psi scale is included, and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of PT, G (BSPP) or NPT threads, manual, automatic or differential-pressure drains, 40 um or 5 um elements, and gauge scale options in MPa, psi or bar. Flow for this series is published as curves rather than a single rated figure, so we confirm flow and other datasheet figures on request 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.

Feeds filtered, regulated air to the actuated valves and grippers on a beverage bottling line, where the 1 in PT connection suits a main drop leg and the automatic drain handles condensate collected in the aluminium bowl.
Supplies the actuation circuit of process valves on a water-treatment skid, where the low-pressure regulator type is chosen for circuits that run below standard line pressure and the 5 um element protects the pilot valves.
Powers diverters, stoppers and clamp cylinders along a warehouse conveyor run, with 5 um filtration removing particulate from shop air before it reaches the directional valves.
Choices within the GFR series that matter when sizing: step up or down through sizes 200, 300, 400 and 600 to match the port and the flow your line needs - this unit is the top of the range at size 600 with a 1 in PT port. Drain type is a real decision: automatic (as here), manual, or the differential-pressure default. Filter grade is 40 um standard or 5 um with code W, as fitted here. Gauges can be the embedded square type or an external round gauge, scaled in MPa, psi or bar. Threads can be ordered in PT, G (BSPP) or NPT; PT is the standard on this code. Brackets are optional - this configuration is supplied without one - and the low-pressure regulator type (L) is selected for circuits running below standard line pressure. Because flow is published as curves rather than a single rating, ask us to confirm sizing 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 GFR600 flow as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure and the flow your downstream circuit needs, and we will confirm sizing against the datasheet on request.
Code A selects the automatic drain: condensate collected in the aluminium alloy bowl is discharged without anyone having to open a drain by hand. The GFR series also offers manual and differential-pressure drain options if a different arrangement suits your installation.
