The AirTAC AirTAC GFR600C20F2WGK Filter Regulator G3/4 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 GFR600C20F2WGK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in one body. This 600-size unit is threaded G3/4 (G thread), carries a 5 um filter element (the finer W grade; 40 um is the standard), drains by differential pressure, and is fitted with an embedded square gauge reading in psi plus a reverse/check valve. The standard regulator covers 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi). At size 600 the bowl is aluminium alloy, and the unit operates from -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 inch, and options for manual or automatic drains, 40 um or 5 um elements, gauge scale in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Filtered and regulated air feeding the tool-change cylinders and pneumatic clamps on a machining centre, with the 5 um element protecting downstream valves from fine particulate.
Steady regulated pressure for the stop, divert and push cylinders along a carton packaging conveyor, with the check valve holding the set pressure against upstream dips.
Point-of-use filtration and regulation ahead of spray guns in a paint booth, where the 5 um element and a stable set pressure support a consistent finish.
Choose the size by port and demand: the 200 to 600 step runs from 1/8 to 1 inch, and this 600 unit sits at the 3/4 inch G thread. Decide the drain: differential-pressure (this model), automatic (A) or manual (M). Pick the element: 40 um standard or 5 um with the W code, as fitted here. Select the gauge scale (MPa, psi or bar) and whether to add a reverse/check valve (K). PT is the standard thread; G and NPT are order options. Flow is published as curves, not a single rating, so have us 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 GFR600 flow as curves rather than a single rated figure, so we do not quote one number. Send us your application details and we will confirm the flow and the full datasheet figures on request.
The W code in the model specifies the 5 um grade, which captures finer particulate than the 40 um standard element. If your line does not need the finer grade, the 40 um version of the same unit is available to order.
