The AirTAC GFR600C20AJF3T AirTAC Filter Regulator NPT3/4 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 GFR600C20AJF3T is an AirTAC GFR600 filter regulator: a single body that removes water and particulate from compressed air and holds downstream pressure steady. This configuration is built for 3/4 in NPT ports, carries an automatic drain that expels collected condensate without operator attention, uses the 40 um standard filter element, and has an embedded square gauge scaled in bar. The regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), the unit accepts a maximum inlet pressure of 1.0 MPa (145 psi), and it operates at -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options include a 5 um filter element (code W), manual or differential-pressure drain, MPa or psi gauge scales, an external round gauge, G or NPT thread in place of the standard PT, and a mounting bracket. Flow for this series 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.

Feeding clean, pressure-stabilised air to a machining centre's pneumatic clamps and tool-change cylinders, where water and chips in the air line cause sticky valves and inconsistent clamping.
Conditioning the air feeding conveyor stopper and pusher cylinders on a packaging line, with the automatic drain clearing condensate through long shifts without an operator walking the line.
Supplying filtered, regulated air to the pneumatic valve manifold that actuates fill, capping and rinse valves in a bottling plant, keeping set pressure steady as demand cycles.
Size and port step up with required flow: the 600 size is the largest in the GFR range, fitted here with 3/4 in NPT threads (PT is the AirTAC standard; G and NPT are order options). Drain choice matters in wet or unattended installations: automatic drain (this unit) handles condensate on its own, manual drain needs an operator, and differential-pressure drain is the catalogue default. Filtration is 40 um standard; choose 5 um (code W) where finer filtration is needed. Gauge scales are MPa, psi or bar - this unit carries the embedded square gauge in bar - and an external round gauge is optional. Flow is published as curves, not a single rating, so send us your flow requirement and we will confirm sizing from 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 rather than a single rated figure, so there is no one number we can quote. Tell us your required flow and line conditions and we will confirm the datasheet curve figures for this 3/4 in NPT unit before you order.
The A in the code means the bowl drains itself: collected condensate is expelled automatically, which suits unattended or high-humidity installations. Manual drain (code M) needs an operator to open it, and differential-pressure drain is the catalogue default. With automatic drain, the regulator adjustment range is 0.15-0.9 MPa (20-130 psi).
