The AirTAC GFR60020AC2TK AirTAC Filter Regulator 3/4 in NPT 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 GFR60020AC2TK is a 600-size filter regulator that cleans compressed air and holds downstream pressure in one body. Water and particulate are removed by the 40 um element into the bowl, while the standard regulator holds your set pressure across the 0.15-0.9 MPa (20-130 psi) adjustment range. This configuration has a 3/4 in NPT port, an automatic drain that expels collected condensate without manual attention, a round external gauge reading in psi, and a reverse/check valve fitted. The aluminium alloy bowl suits this largest 600 frame, and the unit handles up to 1.0 MPa (145 psi) inlet at -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans 200, 300, 400 and 600 sizes with port options from 1/8 to 1 inch, PT as standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um (W) filtration, gauge and scale choices, and a low-pressure type. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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 on a 3/4 in branch line feeding a production hall, it strips water and pipe scale from the shop air and holds a steady set pressure to the tools and machines downstream, with automatic drain keeping the aluminium bowl clear unattended.
Mounted ahead of a cartoner or wrapper's valve manifold, it cleans the incoming air with the 40 um element and locks the supply pressure so cylinders and actuators repeat the same stroke cycle, while the psi gauge gives operators a visible setpoint.
Fitted at the inlet of a pneumatic press or clamping station, it filters the plant supply and regulates clamping force via the 0.15-0.9 MPa adjustment range, with the reverse/check valve holding the downstream setting if upstream pressure dips.
Step up through the GFR sizes (200/300/400/600) as your port and air demand grow; this 600 unit carries a 3/4 in NPT port for higher-flow branch lines. Choose the drain to match access: automatic (as here) where the unit is hard to reach or you want hands-off condensate removal, manual for attended sites, or differential-pressure as the default. The 40 um grade is the standard element; specify 5 um (code W) only where finer particulate protection is needed. The round psi gauge is fitted here; embedded square gauges and MPa/bar scales are the other catalogue choices. PT is the standard thread, with G and NPT as order options - this unit is ordered in NPT. A bracket is included for panel or wall fixing. Because flow is published as curves and not a single rating, 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 GFR flow as curves across the pressure range rather than a single rated figure, so no one number is honest to quote. Tell us your line pressure and the air demand of your equipment and we will confirm the sizing from the datasheet on request before you order.
This configuration carries code A, the automatic drain, which expels collected condensate from the bowl without anyone opening it - useful for units mounted high or in infrequently visited plant rooms. The catalogue alternatives are manual drain (code M) and the differential-pressure drain, which is the default when no drain code is given.
