The AirTAC GFR600-25G AirTAC Filter Regulator G1 (1 in) with Gauge 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 in a single body: it removes water and particulate from compressed air and holds downstream pressure steady, so one 1 in unit does both jobs on a size-600 line. This configuration carries an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, a fitted round gauge reading in psi for direct set-point checks, a reverse/check valve to hold downstream pressure when supply is lost, and a mounting bracket for secure installation. Thread is G (BSPP); PT is the standard thread form for this series, with G and NPT available as order options.
This is a genuine AirTAC part. The GFR range spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, drain choices of differential-pressure, automatic or manual, a 40 um standard or 5 um (code W) element, and MPa, psi or bar gauge scales. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

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 take-off from a factory compressed-air ring main, the GFR600-25 filters line-scale water and rust from the 1 in supply and holds a steady header pressure for the whole department, with the automatic drain handling condensate in a duty point that is not visited daily.
On a bottling or packaging line with many air cylinders and actuators fed from a 1 in trunk line, this unit cleans the air and keeps actuator pressure stable so indexing and clamping stay repeatable, while the psi gauge lets technicians verify set points at a glance.
Feeding a CNC machining centre's pneumatic tool-change and clamping circuits, the 40 um element stops particulate reaching directional valves and the check valve holds downstream pressure through brief supply dips, protecting the machine's air-side sequence.
Step up or down through the GFR sizes (200, 300, 400, 600) against the port you need - here the 600 frame gives the 1 in G connection for higher-flow lines. Choose the drain to suit access: automatic where the unit is hard to reach, manual where you prefer a controlled blow-down, or the differential-pressure default. Pick 40 um for general protection or the 5 um W element for finer pre-filtration, and match the gauge scale (MPa, psi or bar) to your plant standard - this unit ships with a round psi gauge. PT is standard; G and NPT threads are order options, and a bracket is included with this code. Because flow is published as curves rather than one rated number, send us your flow and pressure requirements and we will confirm sizing against the datasheet before you order.
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 on the page. Tell us your working pressure and required flow and we will confirm sizing against the datasheet on request before you order.
The A in the code GFR60025AC2GK specifies an automatic drain, which ejects collected condensate without anyone opening the bowl - useful where the unit is mounted out of easy reach. The GFR family is also available with manual or differential-pressure drains, and with a 5 um filter element (code W) if you need finer filtration than the 40 um standard fitted here.
