The AirTAC GFR600C20AF2K AirTAC Filter Regulator 3/4 in PT, Auto Drain 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 GFR600C20AF2K is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 3/4 in PT port, an automatic drain that bleeds collected condensate without manual attention, the standard 40 um filter element, and an embedded square gauge reading in psi. The reverse/check valve (code K) holds the downstream setting if upstream supply is interrupted, and a mounting bracket is included. At size 600 the bowl is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range with automatic drain is 0.15-0.9 MPa (20-130 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 port sizes from 1/8 in to 1 in, PT as the standard thread and G (BSPP) or NPT as order options, a choice of differential-pressure, automatic or manual drain, a 5 um element (code W) where finer filtration is needed, gauge scale choices, and an optional external round gauge. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application on request.

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.

Point-of-use conditioning for a machining centre's air feed: the 40 um element strips water and swarf-laden condensate before the machine's valves, while the regulator holds a steady setting for clamping and actuation circuits.
Installed at the drop from a factory air header to a packaging machine, the automatic drain handles condensate on a line that is not attended every shift, and the check valve keeps the set pressure stable through supply dips.
Mounted on a bracket inside a control panel, the unit conditions and regulates air to a bank of directional valves, with the embedded square psi gauge giving the panel operator a local pressure readout.
Start with the port step: this unit is the 3/4 in PT size-600 position, the largest in the GFR range, so match it to the air demand of the circuit it feeds - if the required flow is near or above what a 1/2 in line carries, step up to this size. Choose the drain to suit access: automatic (this unit) suits installations that are not checked daily, manual suits attended stations, and differential-pressure drain is the catalogue default. The 40 um element is standard; specify the W option for 5 um only where downstream equipment genuinely needs finer filtration. The embedded square gauge is fitted here reading psi; MPa and bar scales and an external round gauge are alternatives. Thread is PT as standard, with G and NPT available to order, and the bracket is included. Because flow is published as curves rather than a single rating, 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 number, so we do not quote a l/min or SCFM figure. Send us your line size and air demand and we will confirm the datasheet flow curve for this 3/4 in size-600 unit on request.
The A in the code specifies an automatic drain, which expels collected condensate without anyone opening the bowl - useful for unattended installations. The GFR family also offers manual drain and a differential-pressure drain as the default; note that with automatic or differential-pressure drain the regulator adjustment range is 0.15-0.9 MPa (20-130 psi), while manual-drain versions adjust from 0.05 MPa.
