The AirTAC GFR600-20T 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 GFR600-20T is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration has a 3/4 in NPT port, a 40 um standard filter element, an automatic drain that ejects collected condensate without manual attention, and an embedded square gauge scaled in MPa so the set pressure is visible at a glance. The size-600 bowl is aluminium alloy, and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi). Operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of G, NPT or PT thread, manual, automatic or differential-pressure drains, a 5 um element option (code W), square or round gauges with MPa, psi or bar scales, and bracket options. Flow is published as curves rather than a single rating, 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.

Installed on a 3/4 in compressed-air distribution line feeding a production hall, the GFR600-20T removes pipe-scale and condensate and holds a steady regulated pressure for the whole downstream circuit, with the automatic drain keeping the aluminium bowl clear without daily attention.
On a bottling or carton-packing line running pneumatic cylinders and stoppers, this unit supplies clean, regulated air at a fixed setting, and the embedded MPa gauge lets maintenance verify the line set-point at a glance.
Fitted at the air inlet of an automated assembly machine or PLC-controlled panel, the GFR600-20T combines filtration and regulation in one body to protect valves and actuators, with the bracket included for secure panel mounting.
Size and port set the capacity envelope: this is the largest GFR size (600) with a 3/4 in NPT port, chosen when the line's flow demand points to the top of the series - confirm the exact fit from the published flow curves before ordering. The automatic drain suits unmanned or hard-to-reach installations; a manual drain (code M) or the default differential-pressure drain can be ordered instead. The 40 um element is the standard grade; specify 5 um (code W) where finer particulate removal is needed. The fitted square gauge reads in MPa; psi or bar scales and an external round gauge are options. NPT is ordered with the T suffix, with G (BSPP) and PT as the other thread options, and the mounting bracket is included.
Because flow is published as curves and not a single rated figure, send us your application's flow and pressure requirements and we will confirm sizing against the datasheet before you order.
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 GFR series as curves, not as a single rated number, so we do not quote a figure. Tell us your required flow and working pressure and we will confirm the datasheet curve for this 3/4 in, size-600 unit and check it against your application before you order.
The A in the code GFR60020AF1T specifies an automatic drain, which discharges collected condensate from the bowl without manual intervention - useful for unmanned or hard-to-access installations. Manual (code M) and differential-pressure (blank) drains are catalogue options on the same unit if you prefer a different drain behaviour.
