The AirTAC GFR600-25T AirTAC Filter Regulator 1 in NPT, 5 um 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 automatic 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 AirTAC GFR600-25T is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit is fitted with a 1 in NPT port, an automatic drain that expels collected condensate without manual attention, and a 5 um filter element for finer filtration than the standard 40 um grade. The aluminium alloy bowl suits demanding installations, and the external round gauge supplied reads in psi so outlet pressure can be set and monitored directly.
This is a genuine AirTAC part from the GFR series, which spans sizes 200 to 600 with port options from 1/8 in to 1 in and thread choices of PT (standard), G and NPT. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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 0.15 - 0.9 MPa (20 - 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". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard 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. |
| (blank) | No reverse-flow valve (the default). |
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.

Installed on a 1 in compressed-air distribution main feeding a production hall, cleaning up the supply and holding a stable set pressure for the whole downstream circuit, with automatic drain handling condensate.
Feeding the pneumatic actuators and tool-clamp circuits of a CNC machining centre, where the 5 um element protects fine components and the round psi gauge lets maintenance set the exact working pressure.
Supplying the cylinders and air jets on a packaging and conveyor line, combining water and particle removal with pressure regulation in one body to keep diverters and stoppers operating consistently.
Choose the size and port step against the air demand of the circuit: this unit is size 600 with a 1 in NPT port, the largest step in the GFR range, so it suits lines with substantial consumption. Drain type is a real choice: automatic drain (fitted here) suits unattended or hard-to-reach installations, while manual and differential-pressure drains are available in the series. Filter grade is selectable: 40 um standard or 5 um (code W, fitted here) where finer particle removal is needed. Gauge scale can be MPa, psi or bar, and thread can be ordered as PT, G or NPT. Bracket options apply per code. Because flow is published as curves and 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. 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 rather than a single rated figure, so we do not quote a rated flow number. Tell us your application and we will confirm the flow and sizing figures from the datasheet on request.
The code GFR60025AJC2WT decodes to an automatic drain (A), which ejects collected condensate without manual attention, and filter grade W, the 5 um element, which filters more finely than the 40 um standard grade. Manual and differential-pressure drains and the 40 um grade are available as alternative configurations in the series.
