The AirTAC GFR60025ALJF2WT AirTAC Filter Regulator NPT1 Low-Pressure 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 GFR60025ALJF2WT is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built for a 1 in NPT port, carries the 5 um (code W) filter element instead of the 40 um standard, and drains condensate automatically, so it suits lines that cannot rely on someone opening a manual drain. The bowl on this size 600 unit is aluminium alloy. It is the low-pressure regulator type, fitted with an embedded square gauge reading in psi; an external round gauge is available as an option. No mounting bracket is included with this code and no reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with port sizes 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 filtration, and gauge or no-gauge builds. Rated flow for this series is published as curves rather than a single figure, so ask us and we will confirm the datasheet numbers against your application before you order.

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. |
| 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. |

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 stamping or forming press fed from a 1 in air main, this filter regulator cleans the supply and holds a steady low-pressure setting to the press cylinders, with automatic drain keeping condensate out of the bowl during long shifts.
On a beverage bottling line, conveyor stopper and pusher cylinders run continuously; this unit filters the plant air to 5 um and regulates it to the pressure those actuators need, with the psi square gauge giving operators a direct reading.
Air-jet weaving sheds run long 1 in drops to machine panels; this filter regulator conditions each drop, the automatic drain copes with condensate in a humid shed, and the low-pressure type matches the modest setpoints those machines use.
Size and port are the first decision: this unit is size 600 with a 1 in NPT port, the largest step in the GFR range, chosen where the supply line and expected air demand are at the top of the family's span. Drain type is a real choice: automatic (this code) empties the bowl without operator attention, while manual and differential-pressure drains suit attended or intermittent-duty installations. Filtration is 5 um here versus the 40 um standard - pick 5 um where downstream valves and cylinders need finer protection. The gauge on this build is the embedded square type scaled in psi; MPa and bar scales, and an external round gauge, are order options. Thread is NPT on this code; PT is the standard and G is also available. No bracket is fitted on this code, but bracketed versions exist for the GFR family.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated number, so we cannot quote you a rated flow figure here. Send us your line pressure, setpoint and air demand and we will confirm the correct size from the datasheet before you order.
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 GFR series as curves, not as a single rated figure, so we do not quote a rated flow number. Send us your line pressure, pressure setpoint and air demand, and we will confirm the sizing from the datasheet for your application before you order.
The automatic drain expels collected condensate from the aluminium bowl on its own, so the unit suits installations that run unattended. The 5 um element (code W) is one step finer than the 40 um standard element, giving better protection to downstream valves and cylinders. This code is also the low-pressure regulator type with a square psi gauge, no bracket and NPT thread; if you need a different drain, grade, gauge scale or thread, those are available as order options.
