The AirTAC GFR60025AJF3WT AirTAC Filter Regulator NPT1 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 GFR600-25 is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body, so one unit handles both clean-air preparation and set-point control. This configuration is the size 600 unit with a 1 in NPT port, a 5 um filter element (the finer of the two catalogue grades), an automatic drain that expels collected condensate without manual attention, and an aluminium alloy bowl, which is the bowl material used at size 600. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), a square pressure gauge with a bar scale is fitted, and the maximum working (inlet) pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and is available with a choice of drain type, filter grade (40 um standard or 5 um), gauge style and scale, thread option and bracket. 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.

|---|---|
| 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). |
| F | Gauge shape: Square. C is round, F is square. |
| 3 | Gauge scale: bar. 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. |

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.

At a 1 in NPT connection, this unit conditions and regulates the main air drop feeding large cylinders and actuators on a production line, filtering water and particles to 5 um and holding the set pressure automatically drained of condensate.
On packaging or palletizing machinery with many valves and cylinders on one supply, the combined filter-regulator keeps the machine's air clean and at a stable set pressure, with the automatic drain and bar-scale gauge supporting continuous shifts.
For process skids and test rigs where instruments and pneumatic controls need cleaner air, the 5 um element and regulated output from one compact body protect downstream devices, with the aluminium alloy bowl and automatic drain suited to fixed installations.
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 family, suited to lines with substantial supply piping. The two decodable choices that matter most here are the drain and the filter grade: the automatic drain on this unit handles condensate removal on its own, which suits unattended or hard-to-reach installations, while the 5 um element is the finer grade for downstream equipment that needs cleaner air than the 40 um standard. The fitted square gauge reads in bar; MPa and psi scales are the other catalogue options, and an external round gauge is available instead. Thread options are PT as standard with G and NPT as orderable variants - this unit is the NPT version - and the J code means no mounting bracket is fitted. Flow for this family 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. 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, Cv or SCFM number. Tell us your application and required flow, and we will confirm the datasheet figures and check the sizing for you on request.
The A in the code specifies the automatic drain, which ejects collected condensate by itself instead of relying on the differential-pressure action or manual draining - useful where the unit is not checked daily. The W specifies the 5 um filter element, the finer of the two grades (40 um is the standard), chosen where downstream equipment needs cleaner air. Both are catalogue options you can select on any GFR size.
