The AirTAC GFR600C20MF1TK AirTAC Filter Regulator 3/4 in 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 See datasheet 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 GFR600C20MF1TK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 600-size unit is fitted with 3/4 in NPT ports, a manual drain, the standard 40 um filter element, an embedded square gauge scaled in MPa, and a reverse (check) valve. The aluminium alloy bowl suits larger-flow installations, and a mounting bracket is included.
It is a genuine AirTAC part, rated for a maximum inlet pressure of 1.0 MPa (145 psi) and operation from -5 to 70 C in non-freezing conditions. With the manual drain fitted, the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi). The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 in, PT/G/NPT thread options, automatic, manual or differential-pressure drains, 40 um or 5 um (W) filtration, and gauge and scale choices; we confirm flow and datasheet figures 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.

Feeding filtered, pressure-regulated air to spray booths and paint guns on an automotive refinishing line, where water and particulate in the supply would otherwise mark the finish.
Supplying regulated air to pneumatic clamps and tool-changers on a CNC machining cell, holding the set downstream pressure steady as actuators cycle through each part.
Running the cylinders and air jets on a packaging conveyor's carton-sealing station, with the manual drain cleared during scheduled maintenance stoppages.
The real choices in this family are decodable from the code. Size 600 is the largest step, with 3/4 in ports on this unit - step up or down (200/300/400/600) according to the flow your line needs, remembering that flow is published as curves rather than a single rating, so ask us to confirm sizing against your application before ordering. Drain type is manual here (open the drain valve periodically to expel collected water); automatic and differential-pressure drains are available on other GFR variants. Filtration is the standard 40 um element, with 5 um (code W) offered where finer filtration is needed.
The embedded square gauge is scaled in MPa; psi and bar scales, and an external round gauge, are catalogue options. Thread is NPT on this unit; PT (the standard) and G are order options. A mounting bracket is included, and the reverse (check) valve is fitted to hold downstream pressure if the supply drops.
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 this family as curves, not a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow from the datasheet and help you size the unit before you order.
Code M specifies a manual drain: water collected in the bowl is expelled by opening the drain valve during routine checks. Automatic (A) and differential-pressure (blank) drains are catalogue options on other GFR600 variants if you prefer unattended drainage.
