The AirTAC GFR60025LJF3WT AirTAC Filter Regulator 1 in NPT 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 differential-pressure 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 GFR60025LJF3WT is an AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size-600 unit has a 1 in NPT port, a 5 um filter element (the finer of the two published grades), a differential-pressure drain in the aluminium alloy bowl, and a low-pressure regulator type. The embedded square gauge is fitted with a bar scale, and no mounting bracket is included in this configuration.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of ports, drain types (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge scale, thread (PT standard; G and NPT as options) and bracket. Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet 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". |
| (blank) | Drain: Differential-pressure 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. |
| 3 | Gauge scale: bar. 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.

Feeding clamping fixtures and swing cylinders on a machining centre, where the 5 um element protects the clamp valves from water and swarf-carrying condensate and the regulator holds a steady, lower clamping pressure.
A filtered, regulated drop for the pushers, diverters and stopper cylinders along a bottling or carton packaging conveyor, with the 1 in port serving a main header feeding multiple stations.
Conditioning the air ahead of spray guns and air-assisted applicators in a woodworking finishing booth, where the 5 um grade and a stable low-pressure setting give the finish operator consistent atomising air.
Step up or down through the GFR sizes (200/300/400/600) to match the port and flow path your line needs; this unit is the size-600 step with a 1 in NPT port. Choose the drain to suit attendance: differential-pressure (as here, drains on pressure drop), automatic for unattended condensate removal, or manual where someone drains the bowl routinely. Pick 40 um for general protection or 5 um (this unit) where downstream valves and actuators need finer air. Gauge scale (MPa, psi or bar - bar here), thread type and bracket are all decodable choices.
Because AirTAC publishes flow as curves and not a single rated figure, send us your application details and we will confirm sizing against the datasheet before you order. The exact regulation range of the low-pressure type is not published in our sheet; we will confirm it on request.
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 rather than a single rated figure, so we do not quote a number here. Send us your line pressure, downstream demand and this model code, and we will confirm the flow figures from the datasheet for your application before you order.
The W in the code GFR60025LJF3WT selects the optional 5 um filter grade; the catalogue standard is 40 um. The 5 um element removes finer particulate and is the usual choice when protecting precision valves, cylinders or applicators downstream. If your circuit only needs general water and dirt protection, the 40 um version of the same size is also available.
