The AirTAC GFR600C20MC2WK 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 AirTAC GFR600C20MC2WK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built around a PT3/4 port with PT (JIS) thread as the standard connection, a 5 um filter element for finer filtration than the standard 40 um grade, and a manual drain bowl that you empty by hand on your own schedule. A reverse/check valve is fitted to hold downstream pressure, and an external round gauge with a psi scale is included so the set pressure can be read directly. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator covers 0.05-0.9 MPa (7-130 psi), and the operating 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 port options from 1/8 to 1 inch, a choice of manual, automatic or differential-pressure drains, 40 um or 5 um elements, gauge styles and scales, and G or NPT thread variants to order. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application before ordering.

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.

Drops the plant main into a clean, regulated 3/4 inch feed for a machining center's pneumatic tool changes and clamps, with the 5 um element guarding fine pilot valves and the round psi gauge letting setters verify set pressure at a glance.
Conditions the air branch feeding a paint line's spray equipment: water and particulate are stripped out ahead of the regulators that set atomizing pressure, and the manual drain is emptied during scheduled booth cleaning.
Sits at the take-off feeding conveyor stoppers and pusher cylinders on a bottling line, holding a steady regulated pressure so cylinder stroke timing stays repeatable through the shift while the check valve holds the circuit if supply dips.
Step up or down the size ladder (200, 300, 400, 600) against the flow your line needs - larger sizes carry larger ports and more flow, and this size 600 unit takes a 3/4 inch PT port. Choose the drain to match maintenance habits: manual (this unit) is emptied by hand, automatic drains continuously, and the differential-pressure default drains on a pressure-drop trigger. The 5 um element here suits air that feeds sensitive components; the 40 um standard grade is fine for general plant air. Gauge style (embedded square or external round) and scale (MPa, psi or bar - this unit is round, psi) are decodable choices, as is thread: PT is standard, with G (BSPP) and NPT available as order options. A bracket is included for mounting.
One honest note: flow is published as curves, not a single rating, so please 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 flow for the GFR series as curves, not as a single rated number, so we do not quote a figure here. Tell us your application and we will confirm the flow and sizing from the datasheet on request before you order.
The M in the code sets a manual drain: condensate collects in the bowl and is emptied by hand. It suits installations that are visited regularly as part of maintenance rounds. If you need unattended draining, the same family is available with an automatic drain (code A) or the differential-pressure default drain instead.
