The AirTAC GFR600-25MLJC2WK AirTAC Filter Regulator PT1 (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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR600-25MLJC2WK is an AirTAC GFR-series filter regulator: water and particulate removal plus pressure regulation in a single body, sized for a 1 in PT threaded line. This configuration carries a 5 um filter element (the W grade), a manual drain on the aluminium alloy bowl, the low-pressure regulator type, a round pressure gauge reading in psi, and a built-in reverse (check) valve; no mounting bracket is supplied. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
It is a genuine AirTAC part from the largest GFR size, a series that spans sizes 200 to 600 with ports from 1/8 in to 1 in and options for drain type, filter grade, gauge and scale, thread (PT, G, NPT) and bracket. AirTAC publishes flow for this series as curves rather than a single rated figure, so ask us to confirm flow and other datasheet figures against your application before ordering.

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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (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. |
| (blank) | PT 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.

Filtered, gently regulated low-pressure air feeding clamp and hold-down cylinders on a robotic welding fixture, with the built-in check valve guarding the circuit against backflow.
A 5 um element stripping water and fine particles before diverter gates, seal cylinders and small control valves on a carton packaging line, with the manual drain opened at shift checks.
A filter regulator at a machine-shop air drop serving air vices, workholding clamps and actuated valves, with the psi round gauge giving direct pressure setting at the bench.
The real choices in this series are the size and port step (200 to 600, 1/8 in to 1 in), matched to the airflow your line needs; the drain type (differential-pressure standard, automatic, or manual as fitted here); the filter grade (40 um standard, 5 um as on this unit); the gauge and its scale (embedded square gauge standard, external round gauge optional, MPa/psi/bar); the thread (PT standard, G and NPT available to order); and whether a mounting bracket is wanted. This unit is the low-pressure regulator type, and its exact regulation range is not published, so confirm it with us. Flow is published as curves, not a single rating - ask us to check 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 number here. Send us your line pressure and required airflow and we will confirm the sizing from the datasheet on request.
L marks the low-pressure regulator type. The catalogue does not publish an exact regulation range for this low-pressure version, so confirm the range with us before ordering. The unit still carries a 1.0 MPa (145 psi) maximum inlet pressure, a 5 um element, a manual drain and a round psi gauge.
