The AirTAC GFR60025MJF1WTK 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 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 GFR60025MJF1WTK is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure in one body. This configuration is ordered with a 1 in NPT port, a 5 um filter element (the finer of the two available grades), a manual drain on the bowl, a square pressure gauge with MPa scale, and a reverse/check valve fitted. The aluminium alloy bowl suits this largest frame, and the regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi). Operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type, filter grade, gauge style and scale, thread (PT standard; G and NPT as options), bracket and reverse valve. Flow is published as curves rather than a single rating, so ask us to confirm sizing or any datasheet figure for your application before ordering.

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. |
| 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.

Drops from a large compressed-air ring main feeding a production hall: the GFR600 filters bulk water and particulate at the drop and holds a set downstream pressure for the whole cell, with the manual drain emptied during scheduled rounds.
Air supply to large-bore cylinders and actuators on palletising or conveyor lines, where the 1 in port serves high-demand circuits and the regulator keeps actuator speed consistent as upstream pressure wanders.
Conditioning air at service bays and test rigs for commercial-vehicle brake and suspension work, where the 5 um element protects test tooling and the check valve holds settings while supply pressure is cycled.
Size 600 with a 1 in port is the largest GFR frame, so start by matching the port and the flow curve to your line demand rather than to a single rated figure. This unit carries the 5 um element (code W); choose it where downstream equipment needs finer filtration than the 40 um standard, and note the manual drain means an operator drains the bowl on a routine - for unattended drops consider an automatic-drain variant. The square MPa gauge is fitted here; psi and bar scales and an external round gauge are alternatives. Thread is NPT in this code, with PT as the standard and G available to order. No mounting bracket is included in this configuration (code J), and a reverse/check valve is fitted (code K). Flow is published as curves, not a single rating, so 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 number, so we do not quote a l/min, m3/h or SCFM figure. Send us your line demand and upstream pressure and we will confirm the right size from the datasheet curves on request before you order.
The M in the code selects a manual drain: an operator opens the drain to empty collected water, rather than the bowl discharging automatically or on a differential-pressure signal. It suits attended installations with routine checks; if the drop is unattended, ask about automatic or differential-pressure drain variants of the same GFR600 frame.
