The AirTAC GFR60025ALJF2WG AirTAC Filter Regulator G1 Low-Pressure 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 GFR60025ALJF2WG is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure at a set point, in one body. This 600-size unit carries a G1 (1 in) thread, the finer 5 um filter element (code W), an automatic drain that expels collected condensate without manual attention, and the low-pressure regulator type for circuits that run below standard pressure ranges. The embedded square gauge is fitted with a psi scale, and the bowl is aluminium alloy, as fitted to the 600 frame. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), 40 um or 5 um elements, gauge scales in MPa, psi or bar, and G or NPT threads to order. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application before you order.

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". |
| 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. |
| 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. |
| 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. |
| (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.

On a machining fixture that clamps at reduced air pressure, this unit filters the supply to 5 um and holds the set point with the low-pressure regulator, while the psi-scale square gauge lets the setter read the clamping circuit directly.
Feeding spray or coating equipment on a production line, the 5 um element helps protect nozzles and valves from particulate, and the automatic drain clears condensate from the aluminium bowl during continuous shifts without operator attention.
On an assembly machine whose air cylinders run at reduced pressure, the G1 (1 in) port supplies the main air drop, regulation keeps actuation consistent, and the 600-size aluminium alloy bowl suits heavy continuous duty.
Size up by port and flow: the 600 frame with its G1 (1 in) thread is the largest GFR step, so choose it when your line's air demand sits above what the 300/400 frames carry - and confirm against the published flow curves before ordering. This build fixes the real choices for you: the 5 um element (W) instead of the 40 um standard, the automatic drain (A) instead of manual or differential-pressure, the low-pressure regulator type (L), the square gauge on a psi scale (F2), the G thread, and no mounting bracket (J). If your circuit needs a different drain, filter grade, gauge scale, bracket or an NPT thread, those are catalogue options on the same frame.
Because AirTAC publishes flow as curves rather than a single rating, send us your air demand and working pressure and we will confirm this unit's suitability 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.
AirTAC publishes flow for this series as curves rather than a single rated figure, so we do not quote a number here. Send us your air demand and line pressure and we will confirm sizing from the datasheet on request.
The A in the code selects the automatic drain: condensate collected in the aluminium alloy bowl is expelled without manual attention. Manual (M) and differential-pressure (blank) drains are catalogue options on the same frame if you prefer a different service routine.
