The AirTAC GFR60025LJC2WTK 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 GFR60025LJC2WTK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size 600 unit is supplied with a 1 in NPT port, a 5 um filter element (code W), a differential-pressure drain, a fitted round gauge scaled in psi, and a built-in reverse (check) valve. The L in the code marks the low-pressure regulator type; its exact adjustment range is not published, so confirm it against your setpoint before ordering. The aluminium alloy bowl suits this 600 frame, maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, filter grades of 40 um (standard) or 5 um (W), a choice of differential-pressure, automatic or manual drain, and standard or low-pressure regulator types. Thread options are PT (the standard), G (BSPP) and NPT, with bracket and gauge choices selectable. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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. |
| 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. |
| 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.

Feeding a pneumatic press or clamping fixture on a packaging line, where filtered air at a stable low setpoint keeps cycle pressure consistent across shifts.
Conditioning the supply to grippers and actuators on a pick-and-place cell, with the built-in check valve blocking backflow from the downstream side.
Point-of-use conditioning at drop legs on a factory air ring main, filtering scale and condensate before the air reaches valves and cylinders downstream.
Size and port set the flow capacity: this unit is a size 600 with a 1 in NPT port, the largest step in the GFR range, so start there when line demand is high and step down to 200, 300 or 400 if the port exceeds your piping. Choose the drain to match access: differential-pressure (as here) drains while the unit works, automatic drains continuously, and manual suits attended installations. The filter grade here is 5 um (code W); 40 um is the standard element where finer filtration is not required. A round psi gauge is fitted; embedded square gauges and MPa or bar scales are the alternatives. The K code adds a reverse (check) valve, and J means no mounting bracket is supplied. 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your line demand and operating pressure and we will confirm the datasheet curve figures for the GFR600 at 1 in NPT before you order.
The L in GFR60025LJC2WTK marks the low-pressure regulator type, selected where the required set pressure is lower than the standard type covers. Its exact adjustment range is not published, so tell us your target setpoint and we will confirm suitability from the datasheet. Maximum inlet pressure is 1.0 MPa (145 psi) and the temperature range is -5 to 70 C.
