The AirTAC GFR600C25ALF2WGK AirTAC Filter Regulator G1 Low-Pressure 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 GFR600C25ALF2WGK is an AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body, sized for a 1 in port with G (BSPP) thread. This configuration carries the 5 um filter element (the W grade, against the 40 um standard), an automatic drain on the aluminium alloy bowl, the low-pressure regulator type, an embedded square gauge reading in psi, a reverse/check valve, and a mounting bracket.
It is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, drain choices (differential-pressure, automatic or manual), 40 um or 5 um elements, standard or low-pressure regulation, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet 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.

Supply filtered, low-pressure regulated air to pneumatic clamps and swing cylinders on machining fixtures, where a stable low setting protects the workpiece and the 5 um element keeps downstream valves clean.
Feed flap-folders, case clamps and pusher cylinders on a cartoning line, with the automatic drain clearing condensate from the compressed-air header before it reaches the actuators.
Regulate low-pressure atomizing air to spray guns in a paint booth, where the 5 um grade and automatic drain help keep moisture and particles out of the finish.
Size the unit by frame and port: this is the 600 frame on a 1 in G-threaded port, the largest step in the range - step down to 300 or 400 if your circuit runs smaller ports, but match the frame to the flow your line needs. The choices locked into this code are 5 um filtration (W) instead of the 40 um standard, automatic drain, the low-pressure regulator type, a square psi gauge and a reverse/check valve. A bracket is included; the thread here is G (BSPP), with PT as the series standard and NPT orderable. Because AirTAC publishes flow as curves rather than a single rated figure, send us your flow and pressure requirements 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 GFR flow as performance curves rather than a single rated figure, so we do not quote one number. Send us your line pressure and required flow and we will confirm sizing from the datasheet on request.
The L selects the low-pressure regulator variant instead of the standard one, for circuits that sit at the lower end of the adjustment range. The exact adjustment range for this variant is not published in our sheet, so confirm it with us on request before ordering.
