The AirTAC GFR600C20MC3WTK AirTAC Filter Regulator NPT3/4 5um 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 GFR600C20MC3WTK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This 600-size unit carries a 3/4 in NPT port, a 5 um filter element (code W), a manual drain on the aluminium alloy bowl, a round pressure gauge reading in bar, a reverse (check) valve, and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um (W) filtration, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT thread variants. 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.

Feeds clean, pressure-stable air to the clamps, tool-change cylinders and purge circuits of a machining centre, with the 5 um element protecting fine pilot valves from particulate carryover.
Sits at the drop of a packaging line to filter condensate out of the plant air and hold a set pressure to carton-forming, sealing and labelling cylinders as demand fluctuates through the shift.
Conditions the air feeding a robotic workcell's gripper circuit and valve manifold, keeping water and swarf out of the manifold while the regulator pins the supply pressure the cell was set up with.
Size and port set the capacity step: this unit is size 600 with a 3/4 in NPT port, the largest step in the GFR range, so match it to the air demand of the circuit rather than to the pipe alone. Drain type is a real operating choice: manual drain needs an operator to bleed the bowl periodically, while automatic and differential-pressure drains discharge condensate without attention - manual suits machines that are already attended. The 5 um element (W) gives finer protection than the 40 um standard. The gauge on this code reads in bar; MPa and psi scales are available. Thread is NPT here, PT is the standard and G (BSPP) is an order option. Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering.
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 GFR flow as curves, not as a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Send us your application's air demand and we will confirm the sizing against the datasheet curves on request.
The M in the code means the aluminium alloy bowl is drained by hand: an operator opens the drain periodically to remove collected condensate. It suits machines that are attended daily. If the installation is unattended, the differential-pressure (blank) or automatic (A) drain versions discharge condensate without intervention. Note that with a manual drain the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi).
