The AirTAC GFR600C20F3WTK 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 AirTAC GFR600C20F3WTK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a 3/4 in NPT port, a fine 5 um filter element (code W), a differential-pressure drain, an embedded square gauge with a bar scale, a fitted reverse (check) valve, and an included mounting bracket. The large 600-size bowl is aluminium alloy, and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in. Across the family you can order manual or automatic drains, a 40 um standard or 5 um fine element, square or round gauges with MPa, psi or bar scales, G (BSPP) or NPT threads in place of the PT standard, and a no-bracket option. Flow is published as curves rather than a single rating, so ask us and we will confirm the figures from the datasheet 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.

Installed at the take-off point of a factory compressed-air ring main, it dries and filters the supply and holds a set working pressure for the whole cell, with the bar-scale gauge giving operators a local reading.
Feeding cylinders and vacuum generators on a carton packing line, the 5 um element protects valves from particulate while the regulator keeps actuator speed consistent as demand fluctuates along the conveyor.
Mounted on the supply to a pneumatic clamping or light press fixture, it sets and holds the clamping pressure, with the reverse (check) valve fitted downstream of the adjustment and the bracket securing the unit to the machine frame.
Start with the port step: this unit is size 600 with a 3/4 in NPT port, the largest in the GFR range, so step down to GFR200/300/400 with smaller ports if your line is fed at 1/4 to 1/2 in and your flow demand is modest. Choose the drain to match access: differential-pressure (as here) drains automatically as it works, automatic (A) drains continuously, and manual (M) needs someone to open it. Pick the element grade: 40 um is standard for general plant air, while the 5 um W grade (this unit) suits finer downstream equipment. Set the gauge scale - MPa, psi or bar - and choose the embedded square gauge or an optional external round gauge. Thread is PT as standard with G (BSPP) and NPT as order options; brackets can be omitted with code J on the smaller bodies.
One honest note before you order: AirTAC publishes filter-regulator flow as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm sizing against the datasheet curves before you commit.
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 GFR series as curves rather than a single rated figure, so we do not state a number here. Tell us your line pressure, downstream demand and allowable pressure drop, and we will confirm the sizing from the datasheet curves on request before you order.
The W code in the model sets the fine 5 um element instead of the 40 um standard, which suits equipment that tolerates less particulate. The drain code is blank, meaning the differential-pressure type: condensate is expelled automatically as the pressure differential builds, so no manual draining routine is needed. Manual (M) and automatic (A) drains are available as alternative configurations.
