The AirTAC GFR600C25F2GK AirTAC 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 GFR600C25F2GK is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at your set point. This 600-size configuration has a G1 (1 in) G-thread port, a 40 um standard filter element, a differential-pressure drain, a standard regulator adjustable from 0.15-0.9 MPa (20-130 psi), an embedded square gauge reading in psi, and a reverse/check valve fitted. The bowl on size 600 units is aluminium alloy.
This is a genuine AirTAC part. The GFR range spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, PT, G or NPT threads, differential-pressure, automatic or manual drains, a 5 um element option (code W), and gauge scales in MPa, psi or bar. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and 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.

| (blank) | Pressure gauge fitted (blank). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |

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.

Filtered, regulated air to CNC machine-tool valves and spindle-clamp cylinders on a plant air ring main, with the fitted check valve holding downstream pressure during supply dips.
Clean, pressure-stable air for carton-forming and case-sealing cylinders along a packaging conveyor, with the 1 in port feeding a high-demand manifold.
Regulated air to loom and winding-machine pneumatics, where moisture carry-over from the compressor would stain fabric or make machine valves stick.
Choose the size and port step (200/300/400/600, 1/8 in to 1 in) against the air demand of the circuit; this unit is the 600 size with a G1 (1 in) G-thread. Pick the drain: differential-pressure (as fitted here), automatic, or manual - note that the manual-drain version widens the adjustment range down to 0.05 MPa (7 psi). Then choose the 40 um standard element or the 5 um W option, the gauge scale (psi here; MPa or bar available), and PT, G or NPT thread when ordering.
Flow for GFR units is published as curves, not a single rating, so send us your application details and we will confirm sizing from 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 curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and datasheet figures for you before you order.
The differential-pressure drain (the default on this model) bleeds condensate automatically as the pressure differential across the element rises. Automatic (code A) and manual (code M) drains are order options; with a manual drain the regulator adjustment range widens to 0.05-0.9 MPa (7-130 psi).
