The AirTAC GFR600C20AJF3WTK AirTAC Filter Regulator NPT3/4 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 GFR600C20AJF3WTK is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration is built around a 3/4 in NPT port, 5 um filtration (the finer of the two catalogue grades), an automatic drain that expels collected condensate without manual attention, an embedded square pressure gauge reading in bar, and a reverse/check valve that holds the set pressure when the upstream supply is lost. The aluminium alloy bowl suits this large frame, and the unit ships without a mounting bracket.
This is a genuine AirTAC part. The GFR line spans sizes 200, 300, 400 and 600 with a choice of ports, drain types, 40 um or 5 um filtration, gauge scales and thread options, with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing). 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.

Feeds clean, regulated air to the tool-changer and clamping circuits of a machining centre, with 5 um filtration protecting precision valves and the check valve holding clamp pressure if the shop supply drops.
Sits at the head of a bottling conveyor's air drops, filtering condensate out of the mains and holding a steady set pressure to the cylinder banks, while the automatic drain copes with a wet compressor room.
Installed at a work-cell drop in an assembly plant to condition and regulate air for air-driven nutrunners and fixtures, with the bar-scale gauge giving operators a local pressure reference at the station.
Size and port set the capacity: this is the largest GFR frame with a 3/4 in NPT port, so step down to GFR200/300/400 if your line runs smaller ports. Drain type is a real choice - automatic (fitted here) for unattended duty, manual where you prefer controlled blowdown, or differential-pressure as the catalogue default. Filtration is 5 um on this unit versus the standard 40 um; pick 5 um where downstream valves and instruments need finer protection. The square gauge reads in bar; MPa and psi scales are alternatives, and an external round gauge is optional. Thread is NPT here, with PT standard and G (BSPP) as order options; a mounting bracket can be added if you did not want the no-bracket (J) build.
Because flow is published as curves rather than a single rated figure, we cannot quote one number here - send us your application details and we will confirm sizing against the datasheet 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 number here. Tell us your application and required flow, and we will confirm the correct size against the datasheet on request before you order.
The W in the code specifies the 5 um element, the finer of the two catalogue grades (40 um is standard), for protecting sensitive downstream valves and instruments. The A specifies an automatic drain, which expels collected condensate on its own instead of requiring manual blowdown - useful on unattended or high-duty lines.
