The AirTAC GFR600C25AJC1TK 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 GFR600C25AJC1TK is a size-600 filter regulator: it removes water and particulate from compressed air and holds a stable downstream pressure in one body. This configuration carries a 1 in NPT port for high-flow drops, an automatic drain that bleeds condensate from the aluminium alloy bowl without manual attention, a 40 um standard filter element, a fitted round pressure gauge reading in MPa, and a reverse (check) valve. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, and maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um (code W) filtration, gauge styles and MPa/psi/bar scales, and PT, G or NPT threads. We confirm flow and datasheet figures on request, since flow is published as curves rather than a single rating.

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.

Mounted at the drop feeding a machining centre's pneumatic clamps and tool-change cylinders, it strips water and chips-carried particulate from the shop air and holds the clamp circuit at a set pressure so workholding stays consistent through the shift.
Installed on the air drop serving a bottling or cartoning conveyor's stopper and pusher cylinders, it keeps debris and condensate out of the valves while giving the line technician one point to set and read the actuator pressure.
Fitted at a wall-mounted drop feeding assembly stations with air tools and air cylinders, it delivers cleaned air at a regulated pressure, and the automatic drain keeps the large aluminium bowl emptied even where nobody passes daily.
Size 600 with a 1 in port is the largest step in the GFR range, so start here when the line's required flow points to a 1 in connection; smaller 200/300/400 sizes suit lighter duties at lower port sizes. The automatic drain on this unit suits unattended or hard-to-reach installations; choose manual drain where you prefer controlled bleeding, or the default differential-pressure drain elsewhere. The 40 um element is the standard grade; specify 5 um (code W) only where finer particulate protection is needed. The fitted round gauge reads in MPa, with psi or bar scales available as alternatives. Thread here is NPT; PT is the standard catalogue thread and G (BSPP) is also orderable. This unit ships without a mounting bracket (code J), so plan your panel or wall fixing accordingly.
One honest note before ordering: AirTAC publishes flow for this family as curves, not as a single rated figure, so send us your application's flow and pressure requirements and we will confirm sizing against the datasheet before you commit.
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 family as performance curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Send us your required flow and working pressure and we will confirm sizing against the datasheet on request before you order.
The A in the code specifies an automatic drain, which discharges collected condensate from the bowl without anyone opening it - useful for elevated or infrequently visited installations. The same GFR600 body is also available with a manual drain (code M) or the default differential-pressure drain, and with a 5 um element (code W) if you need finer filtration than the standard 40 um.
