The AirTAC GFR600C20C2WTK 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 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 AirTAC GFR600C20C2WTK is a size-600 filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration carries a 3/4 in NPT port, a 5 um filter element (the finer of the two grades), a differential-pressure drain that bleeds collected condensate automatically as flow passes through, a round psi gauge fitted for direct reading of the set pressure, and a built-in reverse/check valve. The aluminium alloy bowl suits this large frame, and the mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the standard 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 is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of drain types, 40 um or 5 um filtration, gauge styles and scales, PT, G or NPT threads, and optional check valves. Flow is published as curves rather than a single rating, 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.

Installed at the take-off point of a factory compressed-air header to remove water and particles and hold a steady, reduced pressure for a production department fed through 3/4 in piping.
Mounted on the supply side of a machine's pneumatic control panel, filtering the incoming air to 5 um and regulating the pressure that feeds the machine's valve manifold and actuators.
Fitted ahead of the air cylinders and control valves on a packaged conveyor system, so the drive receives clean, moisture-reduced air at a fixed regulated pressure.
Size 600 with a 3/4 in NPT port is the step to take when line flow and porting requirements sit above the 300/400 frames; match the port to your piping rather than upsizing blindly, since the true flow figure is published as a curve, not a single rating. The 5 um element (code W) is the right choice where downstream valves, cylinders or instruments are sensitive to finer particles; the standard grade is 40 um if coarser protection is sufficient. The differential-pressure drain handles condensate automatically during flow - choose a manual-drain variant only if the unit will sit at low or intermittent flow. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are the alternatives. NPT is specified here, with PT and G available to order, and the mounting bracket is included. Ask us to confirm sizing against the datasheet curves 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 GFR600 series as curves, not as a single rated figure, so we do not quote a number. Tell us your line pressure, set pressure and required consumption, and we will confirm the flow from the datasheet on request before you order.
The C2 code in GFR600C20C2WTK specifies the optional external round gauge with a psi scale; the embedded square gauge with MPa, psi or bar scales is the standard alternative. The K code adds a reverse/check valve that holds the downstream setting if upstream pressure is lost. Both are order-time choices, as are the drain type, the 40 um or 5 um element, and the PT, G or NPT thread.
