The AirTAC GFR600-25G AirTAC Filter Regulator, G1, 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 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 GFR600-25G is a filter regulator: one body that removes water and particulate from compressed air and then regulates the downstream pressure. This 600-size unit is fitted with a G1 (1 in) port, an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, and a low-pressure type regulator (we confirm its adjustment range from the datasheet on request). A round gauge scaled in psi is fitted, and a reverse (check) valve is built in. The 600-size bowl is aluminium alloy, and this configuration omits the mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um (code W) filtration, gauge scales in MPa, psi or bar, and PT, G or NPT threads. 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 rated figure, so ask us to confirm the 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". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure 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. |
| 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. |
| 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.

On a textile weaving floor, the GFR600-25G filters and regulates the supply feeding air-jet looms, with the automatic drain clearing condensate through long production shifts.
On a beverage bottling line, the unit conditions the air feeding conveyor diverters and gripper cylinders, delivering filtered air at the regulated pressure the actuators require.
In a machining cell, the filter regulator supplies the pneumatic clamps on CNC fixtures, with the psi round gauge letting operators read the set pressure at a glance.
Choose the size and port against the flow your line needs: this 600-size unit carries a G1 (1 in) port, the largest step in the range. Where a bowl is present you pick the drain: differential-pressure (the default), automatic (this unit) or manual; automatic suits unattended installations. Filtration is 40 um standard, with 5 um (code W) where finer protection is needed. Gauges can be the embedded square type or an external round gauge, scaled in MPa, psi or bar - this unit carries a round psi gauge. Threads are PT as standard with G and NPT as order options; brackets are optional and this unit has none. 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 rather than a single rated number, so we do not quote a figure here. Send us your flow and pressure requirements and we will confirm the datasheet figures for this exact configuration before you order.
This unit carries code A, an automatic drain that ejects collected condensate without manual attention - useful on unattended or high-duty lines. The GFR series is also available with a differential-pressure drain (the default) or a manual drain if your maintenance routine prefers either of those.
