The AirTAC GFR600C20AC1WTK AirTAC Filter Regulator NPT3/4 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 GFR600C20AC1WTK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single 600-size body with a 3/4 in NPT port. This configuration carries the fine 5 um filter element (code W), an automatic drain that bleeds collected condensate from the aluminium alloy bowl without manual attention, and a reverse/check valve (code K) fitted. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi) against a maximum inlet pressure of 1.0 MPa (145 psi), and it is supplied with the optional external round gauge on an MPa scale; the embedded square gauge is the catalogue standard and psi or bar scales can be ordered. A mounting bracket is included, and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, G(BCPP)/NPT thread options, gauge choices and scales, and an optional reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and flow 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.

Filter and regulate the 3/4 in supply feeding a cartoning or wrapping machine's valve island, with the automatic drain keeping condensate out of the bowl on a line that runs unattended.
Condition and set a stable working pressure for the air cylinders that clamp and eject parts on a stamping or forming press, with the 5 um element protecting directional valves from particulate.
Supply regulated, filtered air to the stoppers, diverters and lifters along a bottling or parcel conveyor, using the check valve to hold the set pressure if the upstream supply dips.
Step up or down the size ladder (200/300/400/600) to match the port and flow path your line needs; this unit is the 600 size on a 3/4 in NPT thread. Choose the drain to suit access: automatic (this unit) suits unmanned or hard-to-reach installations, manual suits attended stations, and differential-pressure drain is the catalogue default. Choose 5 um (this unit) where downstream equipment such as valves, cylinders or instruments needs finer filtration than the 40 um standard element provides. Gauge scale (MPa/psi/bar), round vs embedded square gauge, PT vs G/NPT thread, the reverse/check valve and the bracket are all real orderable choices. Flow is published as curves, not a single rating, so please ask us to confirm sizing against your application before ordering.
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 rather than a single rated figure, so we do not quote a flow number. Tell us your application and we will confirm the flow/datasheet figures for this 600-size, 3/4 in unit on request.
The automatic drain (code A) discharges collected condensate from the aluminium alloy bowl by itself, which suits installations that run unattended or are awkward to reach. Manual and differential-pressure drains are available as alternative orderable options in the same family.
