The AirTAC AirTAC GFR600C25AF2WGK Filter Regulator 1 in G Thread 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 GFR600C25AF2WGK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This size 600 unit is threaded G1 (1 in, BSPP) and carries a 5 um filter element, an automatic drain on its aluminium alloy bowl, an embedded square gauge scaled in psi, a built-in reverse (check) valve and a mounting bracket. Regulation range is 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature 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 to 1 in, and options include manual or differential-pressure drains, the 40 um standard element, alternative gauge scales (MPa/psi/bar) and PT or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm datasheet figures for your application before ordering.

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 bottling hall's 1 in main air drop, this filter regulator cleans the supply feeding rinse and blow-off nozzles and holds a steady downstream pressure so the nozzles behave consistently shift after shift.
Where a packaging conveyor runs pneumatic clamp, pusher and labelling cylinders off a 1 in header, this unit strips water and 5 um particulate from the air and regulates it to the pressure the cylinder circuit was set up for.
On CNC fixture clamping circuits fed from a 1 in shop-air drop, this filter regulator delivers clean, regulated air to the clamps, and the psi-scaled gauge lets the setter read and verify the clamping pressure at a glance.
Size 600 with the 1 in G (BSPP) port is the largest step in the GFR range; step down to sizes 200/300/400 when the line port and air demand are smaller. This unit pairs the 5 um element (code W) with an automatic drain, which suits installations where condensate should be ejected without someone opening the drain by hand; manual-drain and differential-pressure-drain versions are available if you prefer a different arrangement. The embedded square gauge here reads in psi, and MPa or bar scales can be ordered instead. A reverse (check) valve is fitted, and the mounting bracket is included.
Flow through the GFR600 is published as curves, not as a single rated figure, so please 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 the GFR600 as curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Send us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
The A in the code specifies an automatic drain, which ejects collected condensate from the bowl without someone having to open a drain valve by hand. The same size 600 filter regulator can be ordered with a manual drain or a differential-pressure drain instead, and with the standard 40 um element rather than the 5 um element fitted here.
