The AirTAC GFR60025AJC3WT 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 GFR60025AJC3WT is a GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This size-600 unit is specified with a 1 in NPT port, a 5 um filtering element (the finer of the two available grades), an automatic drain that expels collected condensate without manual attention, an external round pressure gauge scaled in bar, and no mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range is 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). The bowl on size-600 units is aluminium alloy.
This is a genuine AirTAC part. The GFR family is offered 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, with G and NPT as order options) and bracket. Flow is published as curves rather than a single rating, so ask us to confirm the 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 0.15 - 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. |
| 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. |
| (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 at the 1 in header feeding a plant floor, it cleans water and particles from the compressed air and holds a steady regulated pressure for the whole distribution line.
Feeding cylinders and directional valves on a conveyor system, the 5 um element protects seals and seats from particulate while the regulator keeps stroke speed consistent.
Supplying positioners and actuators on automated process valves, the automatic drain keeps condensate out of the actuator and the bar gauge allows a quick setpoint check.
Size and port set the capacity: this is the largest GFR size (600) with a 1 in NPT connection, intended for high-flow supply lines. The 5 um element (code W) suits downstream equipment that needs finer filtration than the 40 um standard; the automatic drain suits unattended installations where condensate must be expelled continuously. The round bar gauge gives a clear external pressure readout, and the NPT thread matches North American piping. Because flow is published as curves and not as a single rated figure, ask us to confirm sizing against your required flow 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 GFR flow as curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and required downstream flow and we will confirm the correct sizing from the datasheet on request before you order.
Code A in GFR60025AJC3WT specifies an automatic drain, which expels collected condensate by itself - useful where the unit is mounted in a hard-to-reach spot. The family also offers manual drain (M) and the differential-pressure drain as the default, and the regulation range differs slightly by drain type: 0.15-0.9 MPa (20-130 psi) for automatic and differential-pressure drains, 0.05-0.9 MPa (7-130 psi) for manual.
