The AirTAC GFR60025ALJF2G AirTAC Filter Regulator G1 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 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 AirTAC GFR600 series combines water and particulate filtration with pressure regulation in a single body. This GFR60025ALJF2G is configured with a G1 (1 in) BSPP thread, the low-pressure regulator type, an automatic drain that clears condensate from the aluminium alloy bowl without operator attention, a 40 um standard filter element, and an embedded square gauge scaled in psi. No mounting bracket is fitted and there is no reverse/check valve. 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 sizes 200 to 600 with ports from 1/8 in to 1 in, PT, G and NPT threads, manual, automatic or differential-pressure drains, 40 um or 5 um (W) elements, and MPa, psi or bar gauge scales. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application.

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. |
| 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.

On a filling or capping line, this unit conditions the compressed air feeding cylinder-driven grippers and pushers: the 40 um element strips water and particulate ahead of the valves, the low-pressure regulator holds a gentle working pressure for delicate container handling, and the automatic drain keeps the aluminium bowl clear between shifts.
At gate, stopper and diverter cylinders along a packaging conveyor, this filter regulator provides clean, regulated air at the low pressures those actuators need, with the square psi gauge giving operators a local setpoint reference and the automatic drain removing accumulated condensate without scheduled attention.
On a workshop test rig or fixture bench, this unit filters the shop air supply and regulates it down to the low working pressure the rig requires, with the 1 in G-thread port suiting larger supply lines, the psi-scaled gauge supporting setup checks, and the automatic drain protecting the bowl in unattended runs.
Size steps from 200 to 600 as port and flow demand grow; this is the 600 size with a 1 in G thread, the largest in the family. Choose the drain to match maintenance practice: automatic (as fitted here) for unattended condensate removal, manual for periodic draining, or differential-pressure. Filter grade is 40 um standard; specify the W variant for the 5 um element where finer particulate matters. The gauge on this model is the embedded square type scaled in psi; MPa and bar scales are available, and an external round gauge is an option. PT is the standard thread, with G and NPT as order options, and brackets are optional. Flow is published as curves rather than a single rating, so 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. 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 GFR600 series as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure and application details and we will confirm the datasheet flow curves and correct sizing on request.
The A in the code selects the automatic drain, which clears collected condensate from the aluminium alloy bowl without operator attention. The same family is also available with manual or differential-pressure drains - ask us for the equivalent code if you prefer a different arrangement.
