The AirTAC GFR600C25F2K AirTAC Filter Regulator 1 in PT Port 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 GFR600C25F2K is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, combining both jobs in one body. This size 600 unit carries a 1 in PT port, a 40 um standard filtration element, and the default differential-pressure drain. The bowl on the 600 size is aluminium alloy, the regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, and an embedded square gauge reading in psi is fitted along with a reverse/check valve (code K) and the mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in up to 1 in, and the series offers a 5 um element (code W), automatic or manual drains, G (BSPP) or NPT thread options, alternative gauge scales, and the low-pressure type. Flow for this series 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.

Feeding filtered, regulated air to the pneumatic nutrunners and clamps at a vehicle assembly station, where the 1 in port serves a high-demand header and the square psi gauge lets line staff verify the set pressure at a glance.
Supplying clean, pressure-stable air to the stopper and pusher cylinders along a bottling conveyor; the 40 um element keeps rust and pipe scale out of the directional valves while the regulator holds a constant setting despite compressor swings.
Protecting the tool-change and workholding clamp circuits of a CNC machining centre: the filter stage strips water and particulate before the valves, and the regulator with its psi gauge keeps clamp pressure where the setup sheet calls for it.
The code fixes every choice on this unit: size 600 with a 1 in PT port at the top of the GFR range, a 40 um element, differential-pressure drain, standard regulator adjusting 0.15-0.9 MPa (20-130 psi), an embedded square psi gauge, a fitted reverse/check valve, and the bracket included. If you need finer filtration, the 5 um W element is the alternative grade; if you prefer hand draining or fully automatic draining, manual (A) and automatic (M) drain versions exist in the same series, with the manual-drain regulator widening the adjustment range to 0.05-0.9 MPa (7-130 psi). Thread can be ordered as G (BSPP) or NPT instead of the PT standard. Because AirTAC publishes flow for this series as curves rather than a single rated figure, send us your pressure and air demand 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 a number. Tell us your working pressure and air demand and we will confirm the flow from the datasheet for this 1 in port size on request.
This unit uses the default differential-pressure drain. The same GFR600 series is also available with an automatic drain (code A) or a manual drain (code M). Note that the regulation range is split by drain type: 0.15-0.9 MPa (20-130 psi) with the differential-pressure or automatic drain, and 0.05-0.9 MPa (7-130 psi) with the manual drain.
