The AirTAC GFR600-25 AirTAC Filter Regulator, G1 (1 in) Port is a genuine G-series filter regulator: water separation, 40 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. This configuration is the size 600 unit with a G1 (1 in) G-thread port, an automatic drain that ejects collected condensate without manual attention, standard 40 um filtration, and an embedded square gauge reading in psi. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of ports, drain types (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge scale, thread option and bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm datasheet figures 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. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) 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.

Filters water and pipe scale from the shop air and holds a steady regulated pressure to spray guns and air-assisted equipment on the paint line, with automatic drain-off of collected condensate.
Feeds clean, regulated air to the pneumatic cylinders and grippers that drive case erecting, taping and palletising stations on a high-throughput packaging conveyor.
Supplies filtered, pressure-regulated air to pneumatic clamps and tool-change actuators on a machining centre, where a stable setpoint keeps workholding consistent across the shift.
Step up or down through the size range (200, 300, 400, 600) to match the port and flow path your line needs; this is the largest, 1 in port unit. Choose the drain to suit access: automatic (this model) where the bowl is hard to reach, manual where an operator is on hand, or the default differential-pressure type. Filtration is 40 um standard; specify 5 um (code W) where downstream equipment needs finer air. The embedded square gauge is fitted here in psi; MPa and bar scales and an external round gauge are alternatives. Thread is G on this unit, with PT standard and NPT available to order, and this configuration 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. 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 no single flow number can be quoted here. Tell us your application and we will confirm the relevant flow and datasheet figures on request before you order.
The automatic drain ejects collected condensate from the bowl on its own, which suits installations where the unit is mounted out of reach or the line runs unattended. Manual and differential-pressure drain versions are available in the same series if you prefer a different arrangement.
