The AirTAC GFR600C20AJF2WK AirTAC Filter Regulator PT3/4 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 AirTAC GFR600C20AJF2WK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, both jobs done in one body. This size 600 unit is ported PT3/4 (3/4 inch, PT thread as standard; G and NPT are order options), carries the 5 um filter element (code W) instead of the 40 um standard, drains collected condensate automatically, and includes the embedded square gauge reading in psi. A reverse/check valve is fitted and no mounting bracket is supplied with this configuration.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with drain, filter-grade, gauge, thread and bracket options. Maximum inlet 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. The size 600 bowl is aluminium alloy. Flow is published as curves rather than a single rating, so ask us to confirm figures against 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 filtered, pressure-stabilised air to the machine's directional valves and pneumatic clamps, with the 5 um element protecting fine pilot components on a 3/4 inch main.
Sits at the head of a packaging or conveyor line's air drop, conditioning supply for cylinders and stopper gates while the automatic drain handles condensate through continuous shifts.
Serves a washdown-adjacent station where moisture carry-over is a risk: the filter stage strips water, the regulator holds a set pressure for air ejectors and grip cylinders.
Work size and port from the air demand of the circuit: this is the 600 size with a 3/4 inch PT port, the largest step in the GFR range, so step down to 200/300/400 if your flow sits lower. Drain choice matters: automatic drain (this unit) suits unattended duty; manual drain suits supervised points; the differential-pressure default needs a pressure drop to trigger. Filter grade is 5 um here (code W) versus the 40 um standard - choose 5 um where valves and instruments need finer air. The gauge is the embedded square type reading psi; MPa and bar scales and an external round gauge are alternatives. Thread is PT standard with G and NPT orderable, and a bracket is optional (not fitted here).
Sizing honestly: flow for this series is published as curves, not a single rated figure, so send us your application details and we will confirm the right size 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 this series as curves rather than a single rated figure, so we do not quote one number. Tell us your application and required flow, and we will confirm the sizing from the datasheet on request before you order.
W is the 5 um filter element, finer than the 40 um standard element. Choose 5 um where downstream valves, cylinders or instruments need cleaner air; the standard 40 um grade suits general water and particulate removal. This unit also has an automatic drain, so condensate is expelled without manual attention.
