The AirTAC GFR60025ALJF1WT 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 GFR60025ALJF1WT is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size-600 unit is built around a 1 in NPT port and is configured with an automatic drain, a 5 um filter element (the W grade), a low-pressure regulator, a factory-fitted embedded square gauge with MPa scale, and no mounting bracket. The aluminium alloy bowl suits the larger 600 frame, and the unit operates in non-freezing conditions from -5 to 70 C at up to 1.0 MPa (145 psi) inlet pressure.
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, ordered with your choice of drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um), gauge scale (MPa, psi or bar) and thread (PT standard, with G and NPT as order options). Flow for this model 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). |
| F | Gauge shape: Square. 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.

Feeds filtered, regulated air to spray guns and finishing equipment on an automotive paint line. The 5 um element helps keep water and particulate out of finish work, the automatic drain clears condensate without operator rounds, and the low-pressure regulator suits processes run at reduced set pressures.
A single-body filter regulator feeding pneumatic cylinders, grippers and diverters on a packaging or conveyor line. Combining filtration and regulation in one unit simplifies the air-prep station, and the 1 in NPT port suits lines with high air consumption at the header.
Supplies filtered, regulated air to pneumatic valve actuators on a water-treatment or process skid. The automatic drain handles condensate in the supply drop, the square MPa gauge gives a local setpoint check at the skid, and the aluminium alloy bowl suits the larger 600 frame.
Match the size and port to the air consumption of your line: this unit is size 600 with a 1 in NPT port, the largest step in the GFR range. Drain type is a real decision - automatic (as fitted here) clears condensate without operator attention, manual (code M) puts discharge under operator control, and the differential-pressure default (blank) is the catalogue standard. Filter grade is 5 um on this model versus the 40 um standard element, so pick the W grade where finer particulate removal matters. The embedded square gauge with MPa scale is fitted; an external round gauge with MPa, psi or bar scales is optional. PT is the standard thread and G or NPT are order options - specify the variant you need when ordering. This unit carries no mounting bracket (code J); brackets are available in the series.
Because flow is published as curves rather than a single rating, send us your application details and we will confirm the datasheet figures and check the sizing against your requirements 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 GFR-series flow as curves rather than a single rated figure, so no rated flow, Cv or SCFM number is quoted here. Tell us your application and we will confirm the datasheet figures and check the sizing for you before you order.
The A in the code means an automatic drain is fitted: collected condensate is expelled from the aluminium alloy bowl without an operator having to open it. Manual-drain (M) and differential-pressure (blank) versions are available in the same series. This unit is rated for non-freezing use from -5 to 70 C.
