The AirTAC GFR60025ALJF2WK AirTAC Filter Regulator 1 in PT 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 GFR60025ALJF2WK is a filter regulator: water and particulate filtration plus pressure regulation combined in one body, with a drain bowl but no lubricator. This 600-size unit carries a 1 in PT port, the fine 5 um (W) filter element, an automatic drain that ejects collected condensate without operator attention, and the L low-pressure regulator type (its exact setting range is not published in the catalogue; we confirm it on request). The embedded square gauge is fitted with a psi scale, a reverse/check valve is fitted, no mounting bracket is included, and the 600-size bowl is aluminium alloy. 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 GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in up to 1 in, a choice of differential-pressure (default), automatic or manual drains, 40 um standard or 5 um (W) filtration, embedded square or optional external round gauges with MPa, psi or bar scales, an optional reverse/check valve, and PT, G or NPT threads (PT is the standard; G and NPT are order options). Flow is published as curves rather than a single rating, so we confirm flow and other datasheet figures on request.

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. |
| (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.

Point-of-use air preparation for gripper and clamp actuators on a bottling line: the 5 um element guards the directional valves against water and particles, the regulator holds a steady supply pressure, and the automatic drain keeps the 1 in aluminium bowl clear without operator rounds.
Feeding a pneumatic press or clamping fixture on a machining line, where the 1 in PT port serves a high-demand circuit, the low-pressure regulator type sets the working pressure, and the fitted reverse/check valve backs up the circuit if upstream supply drops.
A branch filter-regulator on a textile or packaging machine air grid: the square psi gauge gives the operator a local pressure reading, the automatic drain handles condensate in humid plant air, and the 5 um grade protects downstream control valves.
Choose the size by the port and flow step: 200, 300, 400 and 600 map to ports from 1/8 in up to this unit's 1 in, so step up when the circuit demands more air. Pick the drain: automatic (this unit) for unattended condensate removal, manual for periodic draining, or the differential-pressure default. Pick the element: 40 um standard or 5 um (W, this unit) for finer protection of downstream valves. Gauge scale is selectable (MPa, psi or bar; this unit is fitted with a square psi gauge), thread is PT standard with G and NPT as order options, and a mounting bracket can be included or omitted (this unit has none). Flow 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 GFR flow as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, required downstream pressure and air demand, and we will confirm sizing from the datasheet on request.
The A code in this model means an automatic drain that ejects collected condensate from the aluminium bowl without operator attention. AirTAC also offers manual and differential-pressure drains across the GFR range; tell us which you prefer when ordering.
