The AirTAC GFR60020AC1TK 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 PT3/4" ports, a automatic 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 GFR60020AC1TK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is fitted with an automatic drain, so condensate is discharged without manual attention, a 40 um standard filter element, and a round pressure gauge scaled in MPa. The built-in reverse/check valve holds the downstream setting if upstream pressure is lost. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range is 0.15-0.9 MPa (20-130 psi), and the operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part in the largest GFR size, with a 3/4 in NPT port and an aluminium alloy bowl. The GFR600 series is also available with manual or differential-pressure drains, a 5 um element (code W), embedded square gauges, and psi or bar gauge scales. Flow is published as curves rather than a single rating, so we 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.

Installed at the 3/4 in main drop feeding a CNC machining cell, it strips water and swarf-carrying particulate from the plant supply and holds a steady regulated pressure to the machine's air-driven fixtures and clamps.
Mounted ahead of the valve manifold on a carton-forming and palletising line, it delivers clean, regulated air to cylinders and grippers, with the automatic drain coping with condensate from a long, humid supply run.
Fitted at the wall regulator in a heavy-vehicle service bay, it conditions shop air for impact wrenches, air jacks and tyre-cage inflation, with the check valve holding the set pressure during compressor cycling.
Size 600 with a 3/4 in NPT port suits lines with substantial air demand; step down to GFR200/300/400 if your flow curve allows a smaller port. Choose the automatic drain on this model where condensate must be removed unattended, or order manual or differential-pressure drain variants instead. The 40 um element is standard; specify code W for 5 um where finer filtration matters. Gauges can be the embedded square type or an external round gauge in MPa, psi or bar scales, and thread options are PT (standard), G or NPT. 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR600 flow as curves rather than a single rated figure, so no one-number rating exists for us to quote. Send us your required flow and downstream demand and we will confirm the sizing from the datasheet on request before you order.
The automatic drain discharges collected condensate by itself, which suits unattended or hard-to-reach installations and lines with steady moisture loading. If you prefer to control the drain point, the same GFR600 size is available with a manual drain or a differential-pressure drain instead.
