The AirTAC GFR600-25 AirTAC Filter Regulator 1 in PT, 5 um, Auto Drain 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 holds downstream pressure steady in a single body. This size 600 unit is fitted with a 1 inch PT port, a 5 um filter element for finer filtration than the standard 40 um grade, and an automatic drain that expels collected condensate without manual attention. The aluminium alloy bowl suits higher-duty installations, the embedded square gauge reads in psi, and a reverse (check) valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator set range is 0.15-0.9 MPa (20-130 psi), and the operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of drain types, 40 um or 5 um filtration, gauge scale options, PT, G or NPT threads, and bracket choices. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing for your application.

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). |
| F | Gauge shape: Square. 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. |
| (blank) | PT 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.

Feeds clean, regulated air to a machining center's tool-change and clamping circuits, with the 5 um element protecting fine pilot valves and the automatic drain handling condensate from a heavily loaded compressor ring main.
Supplies filtered, regulated air to the gripper and stopper cylinders on a bottling or canning line, where the check valve holds downstream pressure if the upstream supply dips during a compressor changeover.
Serves as the point-of-use filter regulator on a 1 inch assembly-plant air drop feeding pneumatic torque tools and presses, with the psi gauge giving operators a local setpoint readout at the station.
Size 600 with a 1 inch PT port is the largest step in the GFR range; step down to 400, 300 or 200 when your line's flow demand is lower, since port size should track required flow rather than pipe size alone. The 5 um element (code W) suits finer filtration than the 40 um standard; choose automatic drain where condensate loads are continuous or the unit is hard to reach, manual where visits are routine, or differential-pressure drain as the default. The square gauge is fitted here reading in psi; MPa or bar scales and an external round gauge are alternatives. PT is the standard thread, with G (BSPP) and NPT available to order. This code omits the mounting bracket. Because flow is published as curves rather than 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. 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 figure, so we do not quote a number here. Tell us your application's flow demand and we will confirm the sizing against the datasheet curves on request before you order.
This code carries the W option, a 5 um element, which filters more finely than the 40 um standard grade and suits downstream pilot valves and precision actuators. The A option makes the drain automatic, so collected condensate is expelled without manual attention - useful where the unit sits in an inaccessible position or on a continuously wet line. Both are catalogue options; 40 um and other drain types remain available on other codes.
