The AirTAC GFR600C20AC2WTK 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 GFR600C20AC2WTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in one 600-size body. This configuration takes a 3/4 in NPT port, carries the finer 5 um filter element, drains condensate automatically, and is fitted with a round psi gauge and a reverse (check) valve. The aluminium alloy bowl suits the large 600 frame, the standard regulator covers 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, PT as standard and G or NPT to order, plus a choice of manual, automatic or differential-pressure drains, 40 um or 5 um elements, and gauge options. We confirm flow and datasheet figures on request, since flow is published as curves rather than a single rating.

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.

Filtered, regulated air for a CNC cell's pneumatic clamps and tool-change cylinders: the 5 um element protects directional valves from grit and water, while the check valve holds clamp pressure through brief supply dips.
Clean, steady air to spray guns on a paint line: the 5 um element keeps atomising air free of water and particles, the regulator holds a consistent gun pressure, and the automatic drain clears condensate between shifts.
Regulated air for carton-sealer and case-erector cylinders along a packaging conveyor, where the round psi gauge lets technicians set and verify machine pressure at the drop and the auto drain keeps the bowl clear.
Choose the 600 size with its 3/4 in NPT port when your line's air demand sits at the top of the G-series range; the 200/300/400 frames step down in port and capacity. The 5 um element (code W) is the finer choice over the standard 40 um where downstream valves and instruments need cleaner air. The automatic drain (code A) expels collected condensate without daily attention; manual and differential-pressure drains are the alternatives in the same series. The round psi gauge (scale 2) reads setpoints directly, and the fitted check valve holds downstream pressure if upstream supply dips. Thread here is NPT; PT is the standard and G (BSPP) is orderable. Flow is published as curves, not a single rating, so 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 GFR600 series as curves, not as a single rated figure, so we do not quote one number. Send us your required flow and working pressure and we will confirm from the datasheet whether this 3/4 in filter regulator is correctly sized - on request, before you order.
Code A fits an automatic drain that expels collected condensate from the aluminium bowl without operator attention, which suits lines that run unattended or across shifts. Manual (M) and differential-pressure (blank) drains are available in the same series if you prefer a simpler or operator-controlled option.
