The AirTAC GFR60020AC1T 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 GFR60020AC1T is a size 600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in a single body. This configuration carries a 3/4 in NPT port, an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, and a round pressure gauge reading in MPa. The size 600 bowl is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi), the 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. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drain, an optional 5 um element (code W), embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. 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 spray guns and air-assisted applicators on a paint line, where water and particulate must be stripped out and the header pressure stepped down to a steady working setpoint before the air reaches the booth.
Conditioning and regulating the air feeding cylinder-driven diverters, pushers and clamp gates on a bottling or carton-packing conveyor, with the automatic drain handling condensate on a line that runs unattended.
Supplying filtered, regulated air to the workpiece clamps and tool-change cylinders on a machining centre, where a stable setpoint protects clamp force and the 3/4 in port serves a high-consumption main drop.
Size 600 with a 3/4 in NPT port sits at the top of the GFR range; step down to 200, 300 or 400 when your line flow is smaller, and match the port to your piping. Drain type is a real choice: automatic (this unit) suits points that run unattended or are awkward to reach, manual suits attended stations, and the differential-pressure default is the standard option. The 40 um element is the standard grade; specify 5 um (code W) where finer particulate removal matters. Gauge scale (MPa, psi or bar) and thread (PT is the standard; G and NPT are order options) are also decodable choices, and a mounting bracket is included. 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. 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 GFR600 series as curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your application and we will confirm the relevant datasheet figures on request before you order.
The A in the code fits an automatic drain, which ejects collected condensate without anyone opening the bowl. It suits points that run unattended or are hard to reach; manual and differential-pressure drains remain available as decodable options on the same series.
