The AirTAC GFR60025LJF1WTK AirTAC Low-Pressure Filter Regulator NPT1 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 GFR60025LJF1WTK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This size-600 unit is ordered with 1 in NPT ports, the 5 um filter element (code W, against the 40 um standard), a differential-pressure drain, an embedded square gauge scaled in MPa, a reverse/check valve, and no mounting bracket (code J). The bowl on size-600 units is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The regulator is the low-pressure type; its exact setpoint range is not published here, so confirm it with us before ordering.
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, and options for drain type (differential-pressure, automatic or manual), filter grade (40 um or 5 um), gauge style and scale, thread (PT standard; G and NPT to order) and bracket. Flow for this family is published as curves rather than a single rated figure, so ask us to confirm flow and other datasheet figures against 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. |
| 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. |
| 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.

Feeds filtered, regulated low-pressure air to the seal and tuck cylinders of a case-packing line, with the 5 um element protecting the sealing valve set.
Supplies clean air at a gentle, stable setpoint to leak and pressure-decay test fixtures, with the check valve holding the circuit if upstream supply dips.
Regulates the air to gate and diverter cylinders that route bottles between lanes, with the differential-pressure drain keeping the bowl clear during runs.
Choose the size by port and flow: 600 is the largest G-series size, and this unit carries 1 in NPT threads (the trailing T; PT is the standard thread and G/BSPP is also available to order). The drain here is the differential-pressure type, which clears the bowl automatically as pressure differential builds; automatic (A) and manual (M) drains are catalogue alternatives. The W code selects the 5 um element over the 40 um standard - choose 5 um where downstream valves and cylinders need finer air. The gauge is the embedded square type scaled in MPa; psi and bar scales and an external round gauge are options. Code J omits the mounting bracket - order a bracket variant if you panel- or wall-mount. Flow is published as curves, not a single rating, so send us your flow and pressure requirements and we will confirm sizing from the datasheet before you order.
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 the GFR series as curves rather than a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm from the datasheet whether this size-600, 1 in unit suits your application.
The trailing T means this unit is ordered with NPT threads. PT is the standard thread for the GFR series and G (BSPP) is also a catalogue option - specify the thread you need when ordering; it is a specification choice, not a delivery promise.
