The AirTAC GFR600C20ALF2WGK AirTAC 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 GFR600C20ALF2WGK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit carries a G3/4 (BSPP) port, a fine 5 um filter element (code W, against the 40 um standard), an automatic drain that ejects collected condensate without manual attention, and a reverse/check valve. It is the low-pressure type and comes with the embedded square gauge scaled in psi; a mounting bracket is included. The aluminium alloy bowl suits this largest frame in the range.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options for drain type, filter grade, gauge scale, thread form (PT standard, G and NPT to order) and reverse valve. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |

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 plant air main feeding a production hall, cleaning the supply and holding a set low working pressure for the whole downstream circuit.
Mounted ahead of the valve manifold on a packaged conveyor system, supplying filtered, regulated air to the drive and stopper cylinders along the line.
Fitted on the air supply of a truck-mounted tipper or tail-lift kit, where the automatic drain copes with condensate and the check valve holds settings between cycles.
Size 600 with a G3/4 port is the correct step when your line's required flow and existing piping sit at the top of the G-series range; stepping down a size restricts both. The 5 um element (W) is the choice when downstream valves, cylinders or instruments need finer filtration than the 40 um standard. The automatic drain suits unmanned or hard-to-reach installations; manual and differential-pressure drains remain available in the family. The square gauge here reads in psi; MPa and bar scales are alternatives, and an external round gauge is optional. G (BSPP) is the thread on this unit; PT is standard and NPT is orderable. A bracket is included for panel or wall fixing.
Because catalogue flow is published as curves rather than a single rated figure, send us your application details and we will confirm the datasheet and correct sizing 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. Send us your line pressure, downstream demand and port size, and we will confirm the datasheet curve and check the sizing for your application before you order.
The A in the code sets the automatic drain: collected condensate is ejected without manual attention, which suits unmanned or awkward-to-reach installations. The W sets the 5 um filter element, one grade finer than the 40 um standard, for lines feeding valves, cylinders or instruments that need cleaner air. Both choices can be ordered differently within the same GFR600 frame.
