The AirTAC GFR600C20AC3WTK AirTAC Filter Regulator 3/4 in NPT 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 GFR600C20AC3WTK is a size 600 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 3/4 in NPT port, a fine 5 um filter element (code W, versus the standard 40 um), an automatic drain that bleeds collected condensate from the bowl without manual attention, a fitted round gauge reading in bar, and a reverse/check valve. The size 600 bowl is aluminium alloy, and the unit is supplied with a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, in PT (standard), G and NPT threads, with a choice of drain type, filter grade, gauge style and scale, and an optional reverse/check valve. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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 point of a factory compressed-air ring main, it cleans and regulates the branch feed so every machine on that drop sees the same set pressure.
Feeding the valve manifolds on a conveyor and case-packing line, the 5 um element protects directional valves from water and fine debris while the regulator holds consistent actuation pressure.
On a pneumatic test bench, the fine filtration and stable regulated output give repeatable conditions for fixture clamping and instrument-air circuits, with the bar gauge giving a clear local reading.
Size 600 is the largest step in the GFR range, with a 3/4 in port suited to higher-demand lines; step down to 400, 300 or 200 if your flow curve allows a smaller body. The 5 um element (code W) is the right choice where downstream valves and cylinders need finer protection than the standard 40 um; it costs more pressure differential, so match it to the application. The automatic drain suits unattended or hard-to-reach installations; manual and differential-pressure drains are available on other configurations. The fitted round gauge reads in bar; embedded square gauges and MPa or psi scales are the other catalogue options. NPT is ordered as the T thread option; PT is the standard thread and G is also available.
Flow for the GFR series is published as curves, not a single rated number, so we cannot quote a rated flow here. Send us your application details and we will confirm sizing and the datasheet figures 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number here. Send us your application details and we will confirm the datasheet flow figures for this exact 3/4 in NPT, size 600 configuration before you order.
The A in the code GFR600C20AC3WTK selects the automatic drain, which discharges collected condensate from the aluminium alloy bowl without manual attention, and the W selects the 5 um filter element instead of the standard 40 um. Both are catalogue choices: manual and differential-pressure drains and the 40 um element are available on other GFR configurations if you prefer them.
