The AirTAC AirTAC GFR60020AF2TK Filter Regulator 3/4 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 GFR60020AF2TK is a 600-size filter regulator that removes water and particulate from compressed air and holds downstream pressure in a single body. This configuration is threaded 3/4 in NPT, carries the standard 40 um filter element, and has an automatic drain that bleeds collected condensate from the bowl without manual attention. The bowl on size 600 is aluminium alloy, a square embedded gauge reading in psi is fitted, a reverse/check valve is included to hold downstream pressure on supply loss, and a mounting bracket is supplied. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range is 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 is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of PT, G or NPT thread, manual, automatic or differential-pressure drains, an optional 5 um element, MPa, psi or bar gauge scales, and a low-pressure regulator type. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Point-of-use conditioning on the 3/4 in supply feeding a CNC machining cell: the 40 um element strips water and swarf-laden particulate before actuators and tool-change cylinders, while the regulator holds a steady set pressure and the check valve holds it if the main supply drops.
Conditioning the compressed air feeding lab automation and analytical-instrument actuation, where the automatic drain keeps condensate off instruments without daily attention and the psi gauge gives staff a direct read of the regulated set point.
Filtering and regulating the air that drives conveyor stops, diverters and case-packing cylinders on a packaging line, with the 3/4 in NPT connection matching a main distribution leg and the bracket allowing panel or frame mounting beside the take-off.
Size and port are the first choices: the 600 frame with its 3/4 in NPT connection suits the larger end of the range, but the right step depends on the flow your line actually draws, so match the curve to the demand rather than the port alone. Drain type matters in duty terms: the automatic drain on this unit suits unattended or hard-to-reach installations, while manual and differential-pressure drains are the other catalogue options. The 40 um element fitted here is the standard grade; the 5 um (W) element is the option where finer particulate removal is needed. The fitted square gauge reads in psi, with MPa and bar scales available, and an external round gauge is optional. PT is the standard thread; G and NPT are order options, as supplied here. A bracket is included on this configuration.
Because flow is published as curves and not as 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your operating pressure and air demand and we will confirm the flow from the datasheet on request before you order.
The A in the code specifies an automatic drain, which discharges collected condensate from the bowl by itself - useful where the unit is mounted out of reach or on an unattended line. The catalogue alternatives are a manual drain and a differential-pressure drain (the default), and the drain choice also affects the quoted regulation range.
