The AirTAC GFR60025AF2G AirTAC Filter Regulator 1 in G Auto Drain 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 GFR60025AF2G is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is fitted with a G1 (1 in) G-thread port, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, an embedded square gauge reading in psi, and the standard regulator type. Maximum working (inlet) pressure is 1.0 MPa (145 psi), the set-pressure range is 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and can be ordered with a manual or differential-pressure drain instead of automatic, a 5 um element (code W), a psi or bar gauge scale, an external round gauge, a reverse/check valve, or NPT thread in place of G. 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. 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 a 1 in drop from a factory compressed-air ring main, it filters bulk water and particulate out of the supply and holds a steady regulated pressure to the downstream distribution legs.
Feeding the actuator and gripper circuits of a bottling or packaging line, it keeps line pressure constant through shift-long cycling while the automatic drain clears condensate without operator rounds.
Supplying big-bore quarter-turn valve actuators on a process line, it delivers clean, regulated air at the set pressure the actuator and positioner require.
Size 600 with a G1 (1 in) port is the largest step in the GFR range, so size it against the air demand of the line it feeds - flow is published as curves, not a single rating, so ask us to confirm sizing before ordering. This unit has the automatic drain, which suits unattended duty; manual and differential-pressure drains are orderable alternatives. The 40 um element is the standard grade; specify the 5 um (W) option where finer particulate capture is needed. The embedded square gauge here reads in psi; MPa and bar scales and an external round gauge are options. G thread is fitted on this code, with NPT available as an order option, and a mounting bracket is included.
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 this series as curves rather than a single rated figure, so we do not quote a rated flow number. Tell us your application and we will confirm the flow and datasheet figures for you before you order.
The A in the code specifies the automatic drain, which expels collected condensate by itself - useful where the unit is mounted in a hard-to-reach spot or runs unattended. The same size-600 filter regulator can be ordered with a manual or a differential-pressure drain instead if you prefer.
