The AirTAC AirTAC GFR60025ALJC1WT Filter Regulator NPT 1in 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 AirTAC GFR600 series is a filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is built on the size 600 frame with a 1 in NPT port, carries the 5 um filter element (code W, against the 40 um standard), an automatic drain that clears collected condensate from the aluminium alloy bowl without operator attention, the low-pressure regulator type, and a round pressure gauge reading in MPa. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The G-series filter regulator range spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of PT (standard), G or NPT thread, differential-pressure, automatic or manual drains, 40 um or 5 um elements, and square or round gauges in MPa, psi or bar scales. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.
| 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. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT 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.

Filtered, regulated air to spray guns and air-assisted applicators on a paint line, where the 5 um element and the low-pressure regulator type support consistent finish work at the booth.
Feeding clamp and hold-down actuators along a carton packaging conveyor, with the automatic drain clearing condensate from the 1 in main drop without operator rounds.
Supplying pneumatic valve actuators on a treatment-plant skid, with the round MPa gauge giving a clear local pressure readout at the panel.
Size 600 with a 1 in NPT port is the largest step in the G-series; choose size and port against the flow your line needs, and let us check the flow curves with you before ordering. This unit pairs the 5 um element (the 40 um standard element is the alternative where finer filtration is not required) with an automatic drain - differential-pressure (the default) and manual drains are the other catalogue choices if you prefer load-dependent or scheduled condensate removal. The low-pressure regulator type is a decodable variant of this family; its exact adjustment range is not published, so confirm it with us before ordering. The round MPa gauge is fitted here; embedded square gauges and psi or bar scales are options, as are G or NPT threads (PT is the standard) and a mounting bracket (this configuration is ordered without one).
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 filter-regulator flow as curves, not as a single rated figure, so we do not quote a number here. Send us your application's flow and pressure requirements and we will confirm sizing from the datasheet on request.
The automatic drain bleeds collected condensate from the aluminium alloy bowl on its own, which suits unattended installations. Differential-pressure (the family default) and manual drains are also catalogue options if you prefer load-dependent or scheduled draining.
