The AirTAC GFR60025ALJC2K AirTAC Filter Regulator PT1 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 GFR60025ALJC2K is a GFR-series filter regulator: a 40 um filter and a pressure regulator combined in one body, in the 600 size with a 1 inch PT threaded port. This configuration carries an automatic drain that ejects collected condensate without manual attention, a low-pressure regulator type, a round pressure gauge reading in psi, and a reverse/check valve fitted. It is supplied without a mounting bracket, and the bowl at the 600 size is aluminium alloy.
This is a genuine AirTAC part. The G-series filter regulator range spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, an optional 5 um element (code W), gauge and scale options, G or NPT thread variants and optional brackets. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Supplying filtered, regulated air to capping and sealing heads on a beverage bottling line, where the automatic drain keeps condensate out of the valves during continuous production runs.
Feeding pneumatic pusher and stopper cylinders along a carton packaging conveyor, with the 40 um element protecting directional valves from water and particulate carryover.
Providing filtered, reduced-pressure air on a laboratory or workshop test rig where the circuit runs below standard line pressure and the low-pressure regulator type is the right match.
Step up through sizes 200, 300, 400 and 600 to match the port your circuit needs - this unit is the 600 size with a 1 inch PT port, the largest step in the range. Drain type is a real choice: automatic (this code, letter A) needs no routine draining, while differential-pressure and manual versions exist in the same series. The filter element is 40 um as standard; specify code W if the application needs 5 um. Gauge style and scale are selectable, and this code carries a round gauge reading in psi. Thread is PT as standard, with G (BSPP) and NPT available as order options, and a bracket can be added if the code omits it. Note the L in the code: this is the low-pressure regulator type, chosen where the circuit runs below standard line pressure. Flow for this series is published as curves, not 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and datasheet figures for you before you order.
The A in the code means the bowl drains collected condensate automatically, with no routine manual draining. The same GFR series is also available with a differential-pressure drain (the default) or a manual drain, so you can match the drain to how the unit is accessed and how wet your compressed air is.
