The AirTAC AirTAC GFR600C20AF2WGK Filter Regulator 3/4 in, 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 GFR600C20AF2WGK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This size-600 configuration carries a G3/4 (3/4 in) port, a 5 um filter element (code W), an automatic drain that ejects collected condensate without manual attention, an embedded square gauge reading in psi, and a reverse/check valve (code K). The standard regulator covers 0.15-0.9 MPa (20-130 psi) with this drain type, the aluminium alloy bowl suits the 600 frame, and a mounting bracket is included. 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, a choice of 40 um standard or 5 um (W) elements, differential-pressure, automatic or manual drains, gauge scale options 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 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.

Fitted at the drop feeding a CNC machining center, it strips water and particulate from shop air and holds a steady pressure setting for the machine's clamping and actuator circuits.
Mounted at the line side of a carton-sealing or case-packing conveyor, it conditions the air feeding the cylinders and grippers so the drive pressure stays where the line was set.
On a test rig or automated lab bench running air-actuated fixtures, the 5 um element and steady regulated output help protect sensitive pneumatic components from condensate and particles.
Size and port set the capacity: the 600 frame with its 3/4 in port is the largest step in the GFR range, so match it against the flow your line needs before ordering. Choose the drain to suit access - automatic (this unit) clears condensate by itself, manual suits attended installations, and the differential-pressure default is the standard choice. Element grade is 40 um as standard or 5 um with code W; this unit is 5 um, for applications where downstream equipment needs finer air. The embedded square gauge is standard and an external round gauge is optional, with MPa, psi or bar scales - this unit reads psi. Thread is PT as standard with G and NPT as order options; this unit is G. Brackets are optional on GFR and this configuration includes one. 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 GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and the flow your application needs and we will confirm the sizing from the datasheet on request.
This unit carries code A, the automatic drain, which ejects collected condensate without anyone opening the bowl - useful on less-accessed drops. GFR units can also be ordered with manual drains or the differential-pressure default. The regulation range differs by drain type: automatic and differential-pressure cover 0.15-0.9 MPa (20-130 psi), while manual covers 0.05-0.9 MPa (7-130 psi).
