The AirTAC GFR600C20AF2W AirTAC Filter Regulator PT3/4, 5 um 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 See datasheet ports, a differential-pressure 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 GFR600C20AF2W is a 600-size filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a PT3/4 (3/4 in) PT-thread port, a 5 um filter element (code W, finer than the 40 um standard), an automatic drain that expels collected condensate without manual attention, an embedded square gauge reading in psi, and a mounting bracket. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the max working (inlet) pressure is 1.0 MPa (145 psi). Because this is the 600 size, the drain bowl is aluminium alloy; operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is published in 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge and thread options, and a reverse/check valve variant. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing figures for your application on request.

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.

On a 3/4 in branch line feeding big pneumatic cylinders or clamps on a production floor, this unit cleans the supply to 5 um and holds a set working pressure, with the automatic drain keeping condensate out of the bowl unattended.
Packaging machinery with many small valves benefits from clean, regulated air at a stable setting; the 5 um element protects directional valves and the square psi gauge lets operators verify the set point at a glance.
Bench rigs and pilot-scale test stations need particulate-free air at a repeatable pressure; this filter regulator conditions the supply in one body, and the automatic drain suits installations that run without daily checks.
Step up or down through the 200/300/400/600 size ladder to match the port and flow path your line needs; this unit is the 600 size on a PT3/4 (3/4 in) PT connection, with G (BSPP) and NPT threads available as order options. On filtration, 40 um is the standard element and the 5 um (W) fitted here suits downstream equipment that needs finer particulate removal. On drainage, the automatic drain fitted here handles condensate removal on its own, while differential-pressure and manual drains are the other catalogue choices. The embedded square gauge reads in psi; MPa and bar scales and an external round gauge are alternatives. A mounting bracket is included, and a reverse/check valve version exists if you need one.
One honest note before you order: flow for this series is published as curves, not a single rated number, so send us your application details and we will confirm sizing against the datasheet before you commit.
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 as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and sizing figures from the datasheet on request.
This configuration carries code A, the automatic drain, which discharges collected condensate by itself and suits installations that are not checked daily. The catalogue also offers a differential-pressure drain (the default) and a manual drain (code M) if you prefer to control drainage yourself.
