The AirTAC AirTAC GFR60025ALC2WGK Filter Regulator G1 (1 in.) is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1" ports, a automatic 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 GFR60025ALC2WGK is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This size-600 unit is built around a G1 (1 in.) G-thread port, carries a 5 um filter element (the finer of the two catalogue grades), drains condensate automatically, and is the low-pressure regulator type. A round psi gauge is fitted so the set pressure is visible at the unit, and a reverse/check valve is included to hold downstream pressure if the supply is interrupted. The bowl on this size is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR line spans sizes 200, 300, 400 and 600 with ports from 1/8 in. to 1 in., a choice of automatic, manual or differential-pressure drains, 40 um standard or 5 um filtration, gauge and thread options, and standard or low-pressure regulator types. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Feeding filtered, regulated air to a workshop pneumatic press or clamp cylinder bank on a 1 in. main, with the 5 um element protecting directional valves and the automatic drain clearing condensate between shifts.
Conditioning the air supply to carton sealers, case erectors and conveyor actuation on a packaging line, where the low-pressure regulator type sets a gentle working pressure and the psi gauge lets operators verify the setpoint.
Serving as the point-of-use filter regulator at a large assembly cell or test bench fed from the factory header, with the reverse/check valve holding downstream pressure during supply dips and the aluminium bowl suited to a fixed installation.
Work from the port step first: size 600 with a G1 (1 in.) port is the largest step in the GFR range, so match it to the line size your machine or header actually uses rather than upsizing speculatively. Choose the drain to suit access: this unit drains automatically, which suits installations that are not visited daily; manual and differential-pressure drains are the other catalogue choices. This configuration carries the 5 um element (W); the standard grade is 40 um if your application does not need finer filtration. The round psi gauge is fitted here; embedded square gauges and MPa or bar scales are the other options. Thread is G on this unit, with PT standard and NPT available as order options, and a bracket is included for panel or surface mounting. Because flow is published as curves rather than a single rating, 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we do not quote a l/min or SCFM number. Tell us your application and we will confirm the datasheet flow figures for this size-600, G1 (1 in.) unit on request.
The A in the model code selects the automatic drain, which expels collected condensate without manual attention - useful where the unit is mounted in a less accessible spot. The W selects the 5 um filter element, the finer of the two grades (40 um is standard). Both are catalogue options you can order differently if your application prefers.
