The AirTAC GFR600C20MF3WTK AirTAC Filter Regulator NPT3/4, 5 um 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 GFR600C20MF3WTK is a filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at your setpoint. This 600-size unit is threaded NPT3/4 (3/4 in), carries the finer 5 um filter element (code W), and drains by hand through its manual drain (code M). The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), the manual-drain range, and the unit accepts up to 1.0 MPa (145 psi) inlet at -5 to 70 C, non-freezing. The aluminium-alloy bowl suits this 600 size, and the configuration includes the embedded square gauge scaled in bar, a built-in reverse/check valve (code K) and a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, embedded square gauges with optional external round gauges scaled in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

Feeding filtered, regulated air to spray guns and air-assist equipment in a paint booth. The 5 um element catches fine particulate before it can mark a finish, the regulator holds a steady gun pressure, and the manual drain is bled at shift start.
Supplying gripper, pusher and reject cylinders on a beverage bottling conveyor. The 3/4 in port suits a main drop from the ring main, the check valve helps hold the setting if supply dips, and the manual drain is emptied during changeover.
Air preparation ahead of solenoid valves, pallet clamps and tool-change cylinders on a machining centre. The 3/4 in inlet matches the machine's main air connection, and the square bar gauge gives the operator a quick setpoint check at the cabinet.
Step through sizes 200/300/400/600 to match the port and flow your line needs - this unit sits at the top of the range on a 3/4 in NPT port. Choose the drain to suit your maintenance routine: differential-pressure (default), automatic, or manual as fitted here. Filter grade is 40 um standard or 5 um with code W, as on this model. Gauges are embedded square as standard with optional external round gauges scaled MPa, psi or bar; this one is square, bar. Thread is PT as the standard, with G and NPT as catalogue options - this unit is NPT. Brackets are optional on the family and included here. Because flow is published only as curves, not a single rating, send us your demand 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
Flow for the GFR600 is published as curves, not as a single rated figure, so we do not quote a number here. Tell us your downstream demand and working pressure and we will confirm the sizing from the AirTAC datasheet on request.
Code M fits the manual drain: collected water is expelled by opening the drain at the aluminium bowl, so someone needs to do this as part of routine checks. If that does not suit your maintenance schedule, the same GFR600 body is available with an automatic drain (code A) or the differential-pressure drain that is the family default.
