The AirTAC GFR600C25AJC2WTK 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 GFR600C25AJC2WTK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is fitted with a 5 um filter element (code W, finer than the 40 um standard element), an automatic drain that bleeds collected condensate from the aluminium alloy bowl without manual attention, and a round pressure gauge reading in psi. The built-in reverse/check valve holds downstream pressure when the upstream supply is removed, and the unit ships without a mounting bracket. Port is 1 in NPT thread; PT is the AirTAC standard and G/NPT are order options.
This is a genuine AirTAC part in the largest G-series size (600), with 200, 300 and 400 sizes below it and a choice of drain types, filter grades, gauge styles and scales across the range. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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 at the 1 in drop feeding a fabrication or assembly line, it filters water and chips from the header supply, holds a steady regulated pressure for the whole line, and the automatic drain keeps the aluminium bowl clear of condensate without daily attention.
Mounted ahead of a large pneumatic press, clamp fixture or material-handling machine, the 5 um element protects the machine's valves and cylinders from finer contamination, while the check valve holds the machine's set pressure if the main supply is shut off.
Used where a 1 in branch leaves the main header to serve a process area: the regulator sets the branch pressure locally with the psi gauge in view, the automatic drain handles moisture drop-out, and the check valve prevents backfeed from the branch into the header.
Size 600 with a 1 in port is the top G-series step, chosen when the air demand at the machine outruns the 200/300/400 sizes; step down a size only after confirming your flow against the published curves. This unit has the 5 um element (W) rather than the 40 um standard - choose 5 um where downstream valves, cylinders or instruments need cleaner air, and note the finer element loads faster. The automatic drain suits unattended or hard-to-reach installations; manual and differential-pressure drains are the alternatives in this family. The round gauge reads in psi; embedded square gauges and MPa/bar scales are the other catalogue choices. Thread here is NPT; PT (standard) and G are also orderable. No mounting bracket is included with the J code - order one separately if the unit must be panel- or wall-mounted. Because flow is published as curves and not 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 flow for this series as curves, not as a single rated number, so we do not quote a rated flow, Cv or SCFM figure. Tell us your application and line pressure and we will confirm the flow and sizing from the datasheet on request before you order.
The W code in the model means the 5 um element is fitted instead of the 40 um standard, giving finer filtration for downstream valves, cylinders and instruments. The A code is the automatic drain, which expels collected condensate from the aluminium alloy bowl on its own - useful where the unit is not checked daily. A manual or differential-pressure drain can be ordered instead if you prefer.
