The AirTAC GFR600C25AC2WGK AirTAC Filter Regulator G1 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 AirTAC GFR600C25AC2WGK is a size-600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body, handling compressed air at up to 1.0 MPa (145 psi) inlet pressure. This configuration is built around a G1 (1 in) port with G thread, a fine 5 um filter element (code W), an automatic drain that ejects collected condensate without manual attention, and a round pressure gauge reading in psi. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and a reverse/check valve (code K) is fitted to hold downstream pressure. At size 600 the bowl is aluminium alloy, and the unit is supplied with a mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in. Across the series you can order manual or differential-pressure drains, the standard 40 um element or the 5 um option, MPa, psi or bar gauge scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing figures 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 clean, pressure-stable air to spray-booth and paint-line circuits: the 5 um element protects finish quality from particulates, the automatic drain clears condensate between shifts, and the regulator holds a steady set pressure to the guns.
Conditioning the air feeding conveyor stops, clamps and pick-and-place cylinders on a high-throughput packaging line, where the 1 in port matches the main drop line and the check valve holds the circuit against upstream pressure loss.
Supplying filtered and regulated air to workholding clamps and tool-change circuits on a machining centre, with the psi gauge giving operators a direct read of clamp pressure and the 5 um element guarding the machine's pneumatic valves.
Start with the port and size: this unit steps up to G1 (1 in) at size 600, the largest in the GFR range, so match it against the pipe diameter and air demand of the circuit it feeds - if your demand sits below what a 1 in line carries, a smaller GFR size may be more economical. Drain type is a real choice: automatic (fitted here) suits unattended plants, manual drain suits supervised points, and the differential-pressure default drains only when the pressure drop warrants it. Filter grade is 40 um standard or 5 um (code W, fitted here) where finer particulate protection matters. Gauge scale is selectable as MPa, psi or bar - this unit carries a round psi gauge - and thread can be ordered as PT (standard), G or NPT. A bracket is included, and the K code adds a reverse/check valve.
One honest note before ordering: AirTAC publishes flow for this series as curves, not as a single rated number, so we cannot quote you a rated flow figure. Send us your application details and we will confirm the sizing against the datasheet curves on request.
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 performance curves rather than a single rated figure, so we do not quote a rated flow number. Tell us your application - line pressure, downstream demand and acceptable pressure drop - and we will confirm the sizing against the datasheet curves on request.
The A code in the model fits an automatic drain, which ejects collected condensate from the aluminium alloy bowl without operator attention - useful for unattended or elevated installations. The alternatives in the series are a manual drain (code M) for supervised points and the differential-pressure drain (blank code) as the default. Note that with an automatic or differential-pressure drain the regulator adjustment range is 0.15-0.9 MPa (20-130 psi).
