The AirTAC GFR600-25 AirTAC Filter Regulator 1 in PT, Low-Pressure 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 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 size 600 unit is fitted with a 1 in PT port, a manual drain, the standard 40 um filter element and an embedded square gauge reading in psi. It is the low-pressure regulator type, and the aluminium alloy bowl is the specified bowl material at this size.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of manual, automatic or differential-pressure drains, 40 um or 5 um filtration, and G or NPT thread options. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure 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. |
| (blank) | PT 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.

Filtered, regulated air for the pneumatic cylinders and grippers on a beverage bottling line, with the 1 in PT port serving a high-demand header and the manual drain emptied during scheduled changeovers.
Supplies clean, regulated air to the cylinders and ejectors on a carton-forming and sealing conveyor, where the 40 um element helps keep packaging-line valves from fouling and the psi gauge lets operators read line pressure at a glance.
Filtered, low-pressure regulated air for clamps and hold-downs on a machining fixture, with the square psi gauge giving the operator a direct read of set clamping pressure and the aluminium alloy bowl as the specified material at this size.
Size 600 with a 1 in PT port is the largest step in the GFR range - choose it when your line's air demand calls for the biggest ports, and confirm the match against the published flow curves before ordering. This unit is the low-pressure regulator type; its exact adjustment range is not published in our data, so confirm it with us if your set pressure is critical. The drain here is manual: an operator opens the bowl drain periodically, which suits duties with regular maintenance rounds, while automatic and differential-pressure drains are available elsewhere in the series. Filtration is the standard 40 um element - specify code W for 5 um where finer particulate removal matters. The gauge is the embedded square type reading psi (MPa and bar scales are options), no mounting bracket is fitted, and G (BSPP) or NPT threads can be ordered in place of the standard PT.
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, not a single rated figure, so we do not quote a number here. Send us your line pressure, set pressure and air demand and we will confirm the sizing from the datasheet before you order.
The bowl collects water and the drain is opened by hand to empty it, so this unit suits installations with regular maintenance rounds. If you cannot drain on a schedule, the GFR series is also available with automatic or differential-pressure drains - ask us for those codes.
