The AirTAC GFR600C25AC2WK AirTAC Filter Regulator PT1 1 in 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 GFR600C25AC2WK is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This size-600 configuration is threaded PT1 (1 in), carries a 5 um filter element (code W), an automatic drain on the metal bowl, a round gauge reading in psi, and a built-in reverse (check) valve so the regulated downstream pressure holds if the upstream supply drops. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the operating 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 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um (W) filtration, and gauge or no-gauge options. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application.

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.

On a packaging or palletising line, feed the valve manifold and actuator bank from this unit: the 5 um element stops particulate reaching the spool valves, the regulator holds a steady downstream pressure, and the check valve keeps the manifold supplied if the main drop is momentarily lost.
Install this filter regulator at the point where the 1 in plant-air main drops down to a CNC machine, press or assembly cell, removing condensed water from the main line and setting the cell's working pressure locally with the psi gauge to hand.
Use this unit to condition the air feeding cylinder-driven stoppers, gates and pushers along a conveyor system: filtered, regulated air protects the cylinders and valves, and the automatic drain keeps the bowl clear of accumulated condensate during continuous shifts.
Step between GFR200, GFR300, GFR400 and GFR600 to match the port size and expected flow - this 600 body takes a 1 in PT thread (G or NPT threads are order options). Choose the drain to suit the installation: automatic (this unit, which discharges collected water without attention), manual, or differential-pressure; note the regulation range splits by drain type - 0.15-0.9 MPa (20-130 psi) for automatic and differential-pressure drains, 0.05-0.9 MPa (7-130 psi) for manual. Pick 40 um standard filtration or the 5 um (W) element for finer protection, choose the gauge scale (MPa, psi or bar), and add or omit the mounting bracket as the install needs. Flow is published as curves, not a single rating, so 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 G-series flow as curves rather than a single rated figure, so we do not quote a rated flow number for this unit. Tell us your port size, upstream pressure and required downstream flow, and we will confirm the sizing from the datasheet curves on request before you order.
W is the filter grade: a 5 um element instead of the 40 um standard element. A is the automatic drain, which discharges collected condensate without attention (manual and differential-pressure drains are the alternatives, and the regulation range differs by drain type). The C2 in the code is the round gauge reading in psi, and K is the fitted reverse (check) valve. PT is the standard thread; G and NPT are order options.
