The AirTAC GFR60020JC3TK 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 differential-pressure 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 GFR60020JC3TK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is built around a 3/4 in NPT port, the 40 um standard filter element and a differential-pressure drain that bleeds collected condensate automatically as flow passes through. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), a round external gauge scaled in bar is fitted, and a reverse/check valve is included to hold the downstream setting when upstream pressure is lost. Operating temperature is -5 to 70 C (non-freezing) and maximum inlet pressure is 1.0 MPa (145 psi). At size 600 the bowl is aluminium alloy, and no mounting bracket is supplied with this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, a 40 um standard or 5 um (code W) element, gauge and scale options, G/NPT thread variants, and bracket choices. Flow for this series is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet 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.

Installed at the main 3/4 in drop feeding a production hall, it cleans water and scale out of the compressed air and holds a steady regulated pressure for the tools and actuators on that line, with the check valve holding the setting through upstream dips.
Mounted ahead of the valve manifold on a conveyor or packaging line, it dries and filters the air driving the cylinders and protects the downstream regulator setting so the line runs at a consistent pressure shift after shift.
Fitted on the supply to a CNC machine-tool clamping circuit, it strips condensate and particulate before the clamps and holds the clamping pressure stable, with the bar-scaled gauge giving the operator a direct reading at the machine.
Size and port set the capacity: GFR600 with its 3/4 in NPT connection is the largest step in the family, chosen when the line demands the bigger port. Drain type is a real decision - this code uses the differential-pressure drain (default), while automatic (A) and manual (M) versions exist; the drain type also sets the regulation range, so manual-drain versions widen it down to 0.05 MPa. Filter grade is the 40 um standard element here; specify W for the 5 um option if downstream equipment needs finer filtration. The fitted round gauge is scaled in bar; square embedded gauges and MPa/psi scales are alternatives. Thread is NPT on this unit, with G(BSPP) and PT available as order options, and this code ships without a mounting bracket. Because flow is published as curves rather than a single rating, send us your application details 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. 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 number, so we do not quote a figure here. Send us your line pressure, downstream pressure target and expected air demand, and we will confirm the flow data from the datasheet for this exact 3/4 in NPT unit on request.
This code leaves the drain position blank, which is the differential-pressure drain: it purges collected condensate automatically as air flows through, with no operator action. The alternatives are the automatic drain (code A) and the manual drain (code M); note that the drain choice also affects the regulator adjustment range, which is 0.15-0.9 MPa (20-130 psi) on this differential-drain version.
