The AirTAC GFR60025ALJC2G 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 unit, GFR60025ALJC2G, is the size 600 low-pressure type with a 1 in port, G (BSPP) thread, automatic drain, standard 40 um filter element and an external round pressure gauge reading in psi. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the size 600 bowl is aluminium alloy. This configuration is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, drain choices of differential-pressure, automatic or manual, 40 um or 5 um (W) filtration, standard or low-pressure regulation, and gauge options. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures 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". |
| 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). |
| C | Gauge shape: Round. 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.

Filters and regulates the supply to fixture clamps that run on a deliberately low regulated pressure, with the automatic drain clearing condensate from the incoming air.
Conditions the air feeding low-pressure blow-off nozzles that clear dust and debris from product and belt surfaces, protecting downstream valves from water and particulate.
Provides filtered, regulated air to bench-top test rigs and pneumatic circuits that operate below standard line pressure, with a psi gauge for direct reading.
Size 600 is the largest GFR frame, stepping up port and flow capacity from the 200/300/400 sizes; this unit carries a 1 in G-thread port. Drain is automatic here; differential-pressure (blank) and manual (M) are the other catalogue choices. Filtration is the standard 40 um element, with 5 um available as code W. The gauge is the external round type with a psi scale; an embedded square gauge with MPa, psi or bar scales is the standard alternative. Thread: PT is the standard; G and NPT are catalogue order options. Brackets are optional on GFR, and this configuration is ordered without one. As a low-pressure (L) type, this unit regulates below standard line pressure; the exact adjustment range for the low-pressure type is not published in the material we hold, so ask us to confirm it on request. Because flow is published as curves rather than a single rated figure, 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 G-series flow as curves rather than a single rated figure, so no single number applies. Tell us your line pressure, regulated setpoint and downstream demand and we will confirm the sizing from the datasheet on request.
In the code GFR60025ALJC2G, A selects the automatic drain, which expels collected condensate without manual attention, while C2 selects the optional external round gauge with a psi scale. The embedded square gauge is the standard alternative, and differential-pressure and manual drains are also available in the catalogue.
