The AirTAC GFR60025LJF2G AirTAC Filter Regulator 1in G 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 PT1" 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 GFR60025LJF2G is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This size 600 unit has a G1 (1 in) G-thread port, is the low-pressure type, filters to the standard 40 um grade, and drains by differential pressure. Its bowl is aluminium alloy, a square pressure gauge with a psi scale is fitted, no reverse/check valve is fitted, and no mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi); working temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, plus drain choices (differential-pressure, automatic, manual), an optional 5 um filter grade (code W), square or external round gauges in MPa/psi/bar scales, and PT/G/NPT thread options. Flow is published as curves rather than a single rating, so ask us to confirm sizing and any datasheet figure for 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". |
| (blank) | Drain: Differential-pressure 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. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 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. |
| (blank) | No reverse-flow valve (the default). |
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 the control and actuation circuits of a mechanical stamping press, where the 1 in G-thread supply port matches the plant's main drop line and the psi-scale gauge lets maintenance read settings at a glance.
Conditioning air for grippers, diverters and stop gates on a carton packaging conveyor, with the 40 um element catching pipe scale and condensate before it reaches the valve manifold.
Regulating hold-down clamps and light-duty actuation on an assembly fixture, where the low-pressure type regulator suits circuits set below the standard range and the square psi gauge makes set-points straightforward to read.
Size and port step up with flow demand: 600 is the largest GFR size, here with a G1 (1 in) G-thread port - choose it when your line needs the family's largest port, and confirm the exact flow figure against the published curve before ordering. This unit is the low-pressure type, so it suits circuits regulated below the standard range; the exact adjustment range is not published, so confirm it with us. Drain is differential-pressure (the default); automatic (A) and manual (M) versions exist if you prefer. Filter grade is the standard 40 um; specify W for 5 um. The fitted square gauge reads in psi (MPa and bar scales are options), the thread can be ordered as PT or NPT instead of G, and this J-coded unit is supplied without a mounting bracket.
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 GFR flow as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number for this unit. Send us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
The L marks the low-pressure regulator type, intended for circuits regulated below the standard range; the exact adjustment range is not published, so confirm it with us. The blank drain position is the differential-pressure type (automatic A and manual M are alternatives), and the F2 means a square gauge with a psi scale - MPa and bar scales are options.
