The AirTAC GFR600C20AC2GK AirTAC Filter Regulator G3/4 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 GFR600C20AC2GK is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in a single body. This configuration is built around a G3/4 (BSPP) port, a 40 um standard filtration element, and an automatic drain that bleeds collected condensate from the bowl without manual attention. Because it is the 600 size, the bowl is aluminium alloy, and the unit carries a round external gauge reading in psi plus a reverse/check valve (code K) that holds downstream pressure if the supply drops. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 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 options from 1/8 in to 1 in, a choice of automatic, manual or differential-pressure drain, a 5 um element option (code W), gauge scale choices, G/NPT thread variants and bracket options. Flow figures for this series 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.

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 supplied to spray booths and paint guns, where the automatic drain keeps condensate out of the line and the 40 um element stops particulate reaching the finish.
Conditioning the air feeding sealing cylinders and clamp actuators on a packaging conveyor, with the regulator holding a steady setpoint so cylinder stroke timing stays repeatable.
Supplying clean, regulated air to pneumatic workholding clamps on a machining centre, where the check valve helps hold clamp pressure if the main supply dips.
Start with the port and size step: GFR units come in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, so match the step to the air demand of the circuit - we can confirm the flow curve for any size on request. Then pick the drain: automatic (this unit) empties the bowl on its own, manual needs periodic draining, and differential-pressure draining is the default on other codes. Filtration is 40 um standard; choose the 5 um W option where finer protection is needed. Gauges are available as the embedded square type or an external round gauge in MPa, psi or bar scales - this code carries a round psi gauge. Thread is G (BSPP) here; PT is the standard and G/NPT are order options. Brackets are included unless the J (no bracket) code is specified. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application 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 performance curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and air demand and we will confirm the flow curve and correct size from the datasheet on request.
A is the automatic drain (the bowl empties itself instead of manual or differential-pressure draining), C2 is the optional external round gauge with a psi scale, and K means a reverse/check valve is fitted. The 40 um element is the standard grade; a 5 um element is available as code W.
