The AirTAC GFR60025MJF2WTK AirTAC Filter Regulator NPT1 (1 in) 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR60025MJF2WTK is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in a single body. This configuration is built for a 1 in NPT port, with the fine 5 um filter element (code W) for cleaner air than the standard 40 um grade, a manual drain on the bowl for controlled removal of collected condensate, and a reverse/check valve fitted so downstream pressure is held if the supply drops. The embedded square gauge reads in psi so setpoints can be checked at a glance, and the 600-size bowl is aluminium alloy for added robustness.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in and thread choices of PT (standard), G and NPT. Drain, filter grade, gauge style and scale, low-pressure type and check-valve options let you match the unit to the line. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application on request.

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. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). 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". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard 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. |
| 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 filtered, regulated air to a large pneumatic press or forming machine on a 1 in main, where the 5 um element protects valves and cylinders and the check valve holds the circuit if plant air dips.
Conditioning the air header that drives conveyor diverters, clamp cylinders and case-packing actuators, with the square psi gauge letting line staff verify setpoints during changeover.
Supplying regulated air to a workshop rig that tests air-brake components and trailer controls, where the manual drain allows scheduled bowl bleeding between test sessions.
Start with the port and size: this unit steps up to 1 in NPT on the 600 frame, the largest in the GFR range, so size the step against the air demand of the circuit rather than pipe size alone. Because flow is published as curves and not a single rated figure, ask us to confirm sizing against your application before ordering. The 5 um element (W) suits work that needs cleaner air than the standard 40 um grade; the manual drain suits attended installations where an operator bleeds the bowl on a schedule - choose the automatic or differential-pressure drain codes instead for unattended duty. The square gauge here reads in psi; MPa and bar scales and an external round gauge are alternatives. Thread is NPT on this code, with PT standard and G available to order; the J code means no mounting bracket is supplied, so plan the mounting accordingly.
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. Tell us your application and we will confirm the datasheet flow figures and help you check the 600 size against your demand before you order.
The M code specifies a manual drain: condensate collected in the aluminium alloy bowl is released by hand, which suits attended installations on a maintenance schedule. The K code means a reverse/check valve is fitted, holding downstream pressure if the supply side drops. Automatic and differential-pressure drain versions are available under their own codes if unattended drainage is preferred.
