The AirTAC GFR60020F1WTK AirTAC Filter Regulator NPT 3/4 in is a genuine G-series filter regulator: water separation, 5 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 GFR600 series combines water and particulate filtration with pressure regulation in a single body, so one component both cleans the compressed air and sets a stable downstream pressure. This configuration is the size 600 unit with a 3/4 in NPT port, 5 um filtration (the finer W grade instead of the standard 40 um element), a differential-pressure drain that bleeds condensate automatically whenever the pressure differential across the element rises, an embedded square pressure gauge scaled in MPa, and a built-in reverse/check valve that holds the downstream setting if the inlet supply is lost. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the aluminium alloy bowl is suited to the larger 600 frame. A mounting bracket is included.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, square or square/round gauge arrangements 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 before ordering.

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.

Mounted at the drop feeding a CNC machining center, the unit removes water and fine particles from the shop air and holds a steady regulated pressure for the machine's pneumatic tool-changer and clamping circuits, with the check valve holding the setting through supply dips.
Installed ahead of the valve manifold on a bottling or packaging conveyor line, it delivers clean, regulated air to the diverters, pushers and gripper cylinders that position containers, while the 5 um element protects the line's directional valves from fouling.
Used on the air drops of an automated assembly cell, it conditions the supply feeding pick-and-place cylinders and air-driven press fixtures, keeping moisture and grit out of the actuators and giving each cell its own set, monitored working pressure on the MPa gauge.
Step up through the GFR sizes (200, 300, 400, 600) as your port size and air demand grow; this unit sits at the top of the range with a 3/4 in NPT port for higher-flow drops. Choose the 5 um W element when downstream valves, cylinders or instruments need finer protection than the standard 40 um grade, and note that the differential-pressure drain on this model needs no manual attention or auto-drain wiring. If you prefer a psi or bar gauge scale, an external round gauge, a PT or G thread, or a manual-drain version with the wider 0.05-0.9 MPa adjustment range, those are orderable options in the same series. 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 GFR600 series as performance curves rather than a single rated number, so there is no one l/min or SCFM figure we can honestly quote. Send us your line pressure, downstream demand and allowable pressure drop, and we will confirm the sizing from the datasheet on request before you order.
The W in the code GFR60020F1WTK selects the finer 5 um element, which is the right choice when the regulated air feeds sensitive valves, air bearings, measuring equipment or coating processes. The 40 um grade remains the standard option in the series if your application only needs bulk water and coarse particle removal.
