The AirTAC GFR60025AF2 AirTAC Filter Regulator 1 in PT, 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 GFR60025AF2 is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit has a PT1 (1 in) port, an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, and an embedded square gauge scaled in psi so operators can read and set line pressure at a glance. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjustment 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 series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, a 5 um (code W) element option, gauge scale options, G (BSPP) and NPT thread variants, and a reverse/check valve option. Flow is published as curves rather than a single rating, 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 the take-off from a factory compressed-air ring main, it cleans the supply and holds a set pressure for the whole downstream distribution leg on a 1 in line.
Feeding the valve manifolds and air cylinders of a conveyor and case-packing line, it keeps water and debris out of the actuators while holding a stable working pressure.
Mounted ahead of a machine tool's air-powered clamps and tool-change circuit, it delivers filtered air at the regulated pressure the machine builder specifies.
Size 600 with a PT1 (1 in) port is the largest step in the GFR range, so size it where the demand at the point of use is highest; smaller 200/300/400 sizes cover lighter circuits. Choose the drain to suit access: automatic drain (this unit) suits installations that are not checked daily, manual drain suits attended stations, and the differential-pressure default suits general duty. The 40 um element is the standard grade; specify 5 um (code W) where finer particulate removal is needed. The square gauge here reads psi; MPa and bar scales are alternatives, and an external round gauge is optional. PT is the standard thread; G (BSPP) and NPT are orderable options. A bracket is included for panel or wall fixing.
Because flow is published as curves and not as a single rated figure, we do not quote a flow number here. Send us your application details and we will confirm sizing against the datasheet curves before you order.
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 GFR flow as curves, not as a single rated figure, so we do not quote a flow number here. Tell us your line pressure and air demand and we will confirm the sizing from the datasheet curves on request before you order.
The A in the code GFR60025AF2 means the bowl drains itself automatically, which suits installations that are not checked every day. The same size 600 filter regulator is also available with manual drain (code M) or the differential-pressure default, and with a 5 um element (code W), different gauge scales, and G or NPT threads.
