The AirTAC GFR60025MJF1WT AirTAC Filter Regulator NPT 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 GFR600-25MJF1WT is a size-600 filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This configuration is built with a 5 um filter element (the tighter of the two published grades), a manual drain on the bowl, an embedded square gauge scaled in MPa, and a 1 in NPT port. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi). At size 600 the bowl is aluminium alloy, and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um (W) filtration, square (MPa/psi/bar) or external round gauges, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures 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.

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.

Conditioning the air feed to spray guns in a finishing booth: the 5 um element strips water and particulates that would spoil a finish, while the regulator holds the gun supply at the set pressure the painter dials in.
A point-of-use filter regulator ahead of pneumatic clamps and tool-change actuators on a machining centre, keeping coolant-laden, water-carrying shop air out of the clamping circuit and at a stable regulated pressure.
Feeding pilot-air to directional control valves on a bottling or packaging line, where the 1 in port carries the line demand and the regulated, filtered supply keeps valve spools from fouling with water or debris.
Work size and port against the air demand of the circuit: size 600 with a 1 in port is the largest step in the GFR range, so it suits a main or high-consumption drop rather than a small point-of-use line. Choose the drain to match how the unit is serviced: this model has a manual drain, which needs someone to bleed the bowl on a routine; the family also offers automatic and differential-pressure drain options if unattended water removal is preferred. The 5 um element fitted here is the finer published grade; 40 um is the standard alternative where only coarse protection is needed. The square gauge is scaled in MPa, with psi and bar scales and an external round gauge available as options. Thread is NPT here; PT is the catalogue standard and G is also orderable. A mounting bracket is not fitted on this code (J). Because flow is published as curves rather than a single rating, send us your application details and we will confirm sizing against the datasheet before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back 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. Send us your application details and we will confirm the flow behaviour from the datasheet so you can size the unit correctly before ordering.
The M in the code means the bowl has a manual drain: condensate collected by the filter is released by opening the drain by hand on a routine check. If you cannot guarantee that routine, the same GFR600 body is available with an automatic drain (code A) or a differential-pressure drain (blank), which remove water without manual attention. The manual-drain version also carries the wider regulator adjustment range of 0.05-0.9 MPa (7-130 psi).
