The AirTAC GFR600C25AF2WK AirTAC Filter Regulator PT1 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 GFR600C25AF2WK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a PT1 (1 in) port, an automatic drain that expels collected condensate without manual attention, a 5 um filter element (the finer W grade, versus the standard 40 um), an embedded square gauge reading in psi, a reverse/check valve fitted, and a mounting bracket included. At size 600 the bowl is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjustment range with automatic drain is 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with port options by size, PT as the standard thread and G (BSPP) or NPT as order options, a choice of 40 um or 5 um filtration, automatic, manual or differential-pressure drains, and gauge scale choices. Flow for this series is published as curves rather than a single rated figure, so we confirm the datasheet and sizing 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.

Point-of-use preparation for the 1 in main air feed into a CNC machining cell: the 5 um element and regulation keep the machine's pneumatic tool changers and clamps supplied with cleaned, settled air.
Filtering and regulating the air feeding cylinders and diverters on a carton packaging and palletising line, with the automatic drain handling condensate on a line that runs unattended across shifts.
A branch take-off from a factory compressed-air ring main where the 1 in PT port matches the spur line, the reverse/check valve holds the branch setting against upstream dips, and the psi gauge gives operators a local reading.
Start with the port and size step: size 600 with a PT1 (1 in) port sits at the top of the GFR range, so match it against the air demand of the line it feeds - because flow is published as curves rather than a single rating, ask us to confirm the curve against your application before ordering. This unit already carries the finer 5 um element (W); the standard grade is 40 um if a downstream application does not need the finer cut. The automatic drain suits unattended duty; manual and differential-pressure drains are the alternatives in the family. The square gauge is fitted here with a psi scale (MPa and bar scales are the other options), and a reverse/check valve is fitted to hold downstream settings if upstream pressure is lost. PT is the standard thread; G (BSPP) and NPT are order options, and a bracket is included.
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 GFR series as curves, not as a single rated figure, so we do not quote one number. Tell us your application and we will confirm the datasheet curve and sizing for this 1 in size 600 unit on request.
A is the automatic drain: the bowl expels collected condensate on its own instead of needing manual draining. W is the 5 um filter element, one grade finer than the 40 um standard. This unit also carries the K reverse/check valve and a square gauge with a psi scale.
