The AirTAC GFR60020ANTK AirTAC Filter Regulator NPT3/4 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 GFR60020ANTK 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 NPT port, a 40 um standard filter element, an automatic drain that expels collected condensate without manual attention, and a fitted reverse (check) valve that holds downstream pressure when the supply is lost. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and no gauge is fitted, so a separate gauge can be added if visual pressure indication is needed.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, thread options PT (standard), G and NPT, manual or automatic drain choices, a 5 um element option (code W), and gauge options. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures 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.

Installed on a 3/4 in compressed-air distribution main feeding a production hall, the GFR60020ANTK removes water and pipe-scale from the supply and holds a set downstream pressure for the whole line. The automatic drain keeps condensate moving out of the bowl without an operator round, and the check valve protects the downstream circuit if the compressor unloads.
On a packaging line where cylinders and air-operated valves run continuously, this unit filters the incoming air to 40 um and regulates it to the pressure the actuators were set up for. The automatic drain suits lines that run across shifts, and the included bracket fixes the unit to the line's backplate.
In a workshop bay servicing commercial-vehicle air systems, this filter regulator conditions shop air before it reaches test benches and inflation stations. The 3/4 in NPT port matches the bay's supply drops, the check valve holds the set pressure during compressor cycling, and the automatic drain copes with the moisture carried in high-volume shop air.
Size 600 is the largest step in the GFR range, with a 3/4 in NPT port suited to higher-flow supply lines; step up or down through 200/300/400 to match the line. The automatic drain on this unit suits unattended installations; a manual-drain variant is available where you prefer scheduled draining. The 40 um element is the standard grade for general plant air; specify the W code for the 5 um grade where downstream equipment needs finer filtration. Note that the automatic-drain configuration gives a 0.15-0.9 MPa (20-130 psi) adjustment range, while manual-drain variants widen the lower end to 0.05-0.9 MPa. This unit ships without a gauge; gauge options with MPa, psi or bar scales can be ordered. NPT is the thread on this code; PT is the catalogue standard and G is also available. A mounting bracket is included.
Flow for this family is published as curves, not a single rated number, so we cannot quote a rated flow figure. Send us your application details and we will confirm sizing against the datasheet curves before you order.
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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your line size and application and we will confirm the flow figures from the datasheet curves on request before you order.
The N code in GFR60020ANTK means no gauge is fitted. The GFR family accepts gauge options, including an embedded square gauge or an external round gauge with MPa, psi or bar scales, so you can order a gauge-equipped variant or add indication downstream if you need to read the regulated pressure.
