The AirTAC GFR600C20C2WK AirTAC Filter Regulator PT3/4, 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 GFR600C20C2WK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This size-600 unit is fitted with a PT3/4 port, a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain that bleeds collected condensate automatically when the pressure differential rises, a round pressure gauge reading in psi, and a built-in reverse/check valve that holds downstream pressure if the supply drops. The maximum working pressure is 1.0 MPa (145 psi), the regulation range is 0.15-0.9 MPa (20-130 psi), and the operating temperature is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family is published in four sizes (200, 300, 400 and 600) covering ports from 1/8 to 1 inch, with a choice of 40 um standard or 5 um (W) filtration, differential-pressure, automatic or manual drains, square or round gauges in MPa, psi or bar scales, a low-pressure regulator option, an optional reverse/check valve, and PT, G or NPT threads. Flow for this model is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing figures on request.

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 clamping cylinders and pneumatic presses on a fabrication line, where the 5 um element protects directional valves from particulate and the regulator holds a consistent clamping pressure shift after shift.
Supplying the air cylinders that erect, fill and seal cartons on a packaging conveyor, with the check valve holding cylinder position during brief supply dips and the differential-pressure drain keeping condensate out of the line.
Actuating pneumatic process and divert valves on a bottling or filling line, where regulated pressure gives repeatable valve stroke timing and the 5 um grade suits sensitive pilot-operated valve internals.
Start with the port and size: GFR600 carries a 3/4 inch PT port, the largest step in the range, so size up from 300/400 if your line's air demand sits near what a smaller body can pass - and ask us to check the published flow curve against your consumption before ordering, since AirTAC gives flow as curves rather than one rated number. Choose the filter grade: 40 um is the standard element for general protection, while this unit's 5 um (W) element suits finer downstream equipment. Choose the drain: differential-pressure (fitted here) needs no operator, automatic drains continuously, and manual suits periodically attended installations. Pick the gauge scale (MPa, psi or bar) and square or round style; this configuration carries a round psi gauge. Specify PT as standard or order G (BSPP) or NPT when your pipework demands it, and add or omit the mounting bracket as the installation requires. The reverse/check valve (K) is worth specifying where downstream pressure must be held through a supply dip.
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 performance curves rather than a single rated figure, so no one rated number exists to quote. Send us your line's air demand and working pressure and we will confirm the sizing against the datasheet curves on request before you order.
The W in the code specifies the 5 um filter element instead of the 40 um standard grade, giving finer protection for sensitive downstream equipment, and the K specifies a built-in reverse/check valve that holds downstream pressure if the upstream supply drops. Both are catalogue options you can include or omit when ordering any GFR unit.
