The AirTAC GFR600C25ALC2WT AirTAC Filter Regulator NPT1 (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 GFR600C25ALC2WT is a size 600 filter regulator: it removes water and particulate from compressed air through a 5 um element and regulates downstream pressure with its low-pressure type regulator, all in one body. This configuration has a 1 in NPT port, an automatic drain that expels collected condensate without operator attention, an aluminium alloy bowl, and a round pressure gauge reading in psi. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options across the range include manual or differential-pressure drains, the 40 um standard element in place of the 5 um W grade, embedded square or external round gauges in MPa, psi or bar scales, a reverse/check valve, and G (BSPP) or NPT threads in place of the PT standard, with a mounting bracket included. 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.

Filtered, regulated low-pressure air for tool-clamp and chip-blow circuits on a machining centre, with the 5 um element protecting precision valves and the automatic drain clearing condensate during continuous running.
Low-pressure regulated air supply to diverters, pushers and stopper cylinders along a bottling conveyor, where the 5 um filtration keeps water and debris out of directional control valves.
Water and particulate removal ahead of air-jet nozzles on weaving machines, with the round psi gauge letting operators check the setpoint at the loom and the automatic drain handling condensate load through long shifts.
Size 600 with a 1 in NPT port is the largest step in the GFR range; step down to the 200, 300 or 400 sizes and smaller ports if your demand is lower, since port size tracks the flow curve. The 5 um element (code W) suits points of use that need finer air than the 40 um standard, and the automatic drain suits installations that run unattended, with manual and differential-pressure drains as the alternatives on other configurations. This unit carries a round gauge reading psi (MPa and bar scales are available) and includes a mounting bracket; the low-pressure regulator type is a decodable variant whose exact regulating range is not published, so confirm it with us. The thread here is NPT; PT is the catalogue standard and G (BSPP) is the other order option. Because flow is published as curves, not a single rating, send us your application conditions 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.
Flow for this unit is published as curves, not as a single rated number, so we do not quote a figure here. Send us your application conditions - inlet pressure, downstream demand and acceptable pressure drop - and we will confirm the sizing from the AirTAC datasheet on request.
The A in the code specifies the automatic drain, which expels collected condensate without operator attention - useful for unattended or hard-to-reach installations. Manual and differential-pressure drains are the other catalogue options across the GFR range. The round gauge fitted here reads psi; MPa and bar scales are available on other configurations.
