The AirTAC GFR600C25ALJC2G 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 AirTAC GFR600 series combines water and particulate filtration with pressure regulation in a single body. This GFR600C25ALJC2G is configured with a G1 (1 in) G-thread port, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, and the low-pressure regulator type. A round pressure gauge reading in psi is fitted, the unit is ordered without a mounting bracket, and the reverse/check valve is not fitted. Maximum inlet pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C (non-freezing), and the metal bowl is aluminium alloy at this size 600.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um (W) filtration, standard or low-pressure regulation, gauge and thread options, and bracket or no-bracket ordering. Because flow is published as curves rather than a single rating, we confirm datasheet figures 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.

Filtered, regulated air at the 1 in main drop feeding case erectors, clamp cylinders and grippers; the automatic drain clears condensate without a daily walk-round.
Looms that run on low set pressures take clean, regulated air from this size 600 unit, with the 40 um element protecting jet and nozzle circuits upstream of finer point-of-use filters.
Low-pressure regulation suits large-bore gate and stopper cylinders on filling lines, where the round psi gauge lets line staff verify set points at a glance.
Size and port step up with flow demand: 200 through 600, with this size 600 unit carrying the 1 in (G1) port for the largest supply lines in the family. Choose the drain to match the installation: automatic (as here) suits unattended or hard-to-reach points, manual suits regularly serviced drops, and the differential-pressure default suits standard duty. Filter grade is 40 um standard; specify W for the 5 um element where downstream equipment needs finer filtration. Gauge scale (MPa, psi or bar), thread (PT standard, G or NPT to order) and bracket are all decodable options. Flow is published as curves, not a single rating, so 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 no single number would be honest. Send us your line pressure, set pressure and expected air demand, and we will confirm sizing against the datasheet curves before you order.
The A in the code selects the automatic drain, which expels collected condensate without manual attention - useful for elevated, enclosed or infrequently visited installations. Manual and differential-pressure drains remain available in the same size if your maintenance routine prefers them.
