The AirTAC GFR60025LJC1WTK 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 GFR60025LJC1WTK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This 600-size unit carries a 1 in NPT port, a 5 um filter element (code W), the differential-pressure drain, the low-pressure regulator type, a round gauge on an MPa scale, and a reverse/check valve. The bowl is aluminium alloy, the material used at size 600.
This is a genuine AirTAC part. The GFR series spans sizes 200 to 600 with ports from 1/8 in to 1 in, a choice of drain types, 40 um standard or 5 um filtration, gauge and thread options, and bracket choices. Flow is published as curves rather than a single rating, so ask us to confirm sizing figures and the full 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). |
| C | Gauge shape: Round. 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.

Point-of-use preparation for wide-bore blow-off and pellet-conveying runs in plastics and packaging plants, where the 1 in NPT connection feeds air knives and ejector nozzles from a main header.
Filtered, regulated supply to gate, stopper and diverter cylinders on bottling and canning conveyor lines, with the 5 um element protecting the directional valves that position the gates.
Air preparation for fixture clamps and swing cylinders on CNC machining cells, where the low-pressure regulator type and the fitted reverse/check valve match the circuit arrangement downstream.
Size and port step up with demand: this is the 600 frame with a 1 in NPT connection, the largest in the series. The 5 um element (code W) suits circuits with finer-tolerance valves; the standard grade is 40 um. The drain here is the differential-pressure type (the default); automatic (A) and manual (M) drains are alternatives. The gauge fitted is the external round type on an MPa scale; the embedded square gauge and psi or bar scales are options. Thread is NPT here; PT is the standard and G (BSPP) is available to order. No mounting bracket is included. This is the low-pressure regulator type; its exact adjustment range is not published, so confirm it with us. Flow is published as curves, not a single rating - 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet on request.
This unit uses the differential-pressure drain, the default code: it discharges collected condensate as the pressure differential across the element rises. Automatic (A) and manual (M) drain versions are available in the series if you prefer a different arrangement.
