The AirTAC AirTAC GFR600C20LF2WGK Filter Regulator G3/4, 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 GFR600C20LF2WGK is a filter regulator: water and particulate removal plus pressure regulation combined in a single 600-size body with a G3/4 (BSPP) port. This configuration carries the 5 um filter element (code W) for finer air cleaning than the standard 40 um grade, a differential-pressure drain that bleeds accumulated condensate automatically when the pressure differential across the element rises, and a low-pressure regulator type for circuits that run below standard working pressures. An embedded square gauge scaled in psi is fitted, a reverse/check valve is included, and the 600-size bowl is aluminium alloy. A mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of PT (standard), G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge or no gauge, and standard or low-pressure regulation. Flow is published as curves rather than a single rating, so ask us to confirm sizing and any datasheet figure against 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.

Feeds filtered, regulated air to pneumatic clamps and fixtures that hold workpieces during milling or turning, where the low-pressure regulator type matches a circuit that runs below standard line pressure and the 5 um element protects sensitive valve spools.
Mounted at the air inlet of a cartoning or wrapping machine, it removes water and fine particulate before the actuator manifold and holds a stable supply pressure to the sealing and pusher cylinders, with the psi gauge giving operators a local reading.
Installed where a 3/4-inch branch line serves a production department, it conditions air for that section independently of the main header, with the reverse/check valve holding downstream pressure if the upstream supply is interrupted.
Start with the size and port: 600 is the largest G-series size, with a G3/4 port suited to the higher end of the range's flow capacity - match it to your line's demand and let us confirm the flow curve for your conditions. Choose the drain type where it applies: differential-pressure (as fitted here) drains on element loading, automatic drains on a timer-free basis, and manual requires operator action. Filter grade is a real choice: 40 um standard or 5 um (the W code on this unit) when downstream equipment needs finer air. Gauge scale is selectable (MPa, psi or bar), and thread is PT as standard with G and NPT as order options - this unit is the G-thread version. A bracket is included on this configuration.
One honest note on sizing: flow is published as curves, not a single rated figure, so we cannot quote a rated flow number. Send us your application details 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.
AirTAC publishes flow for this series as curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your application details - line pressure, downstream demand and acceptable pressure drop - and we will confirm sizing against the datasheet on request before you order.
The W code in the model sets the 5 um filter grade instead of the 40 um standard, for finer removal of water and particulate ahead of sensitive equipment. The F2 code sets the embedded square gauge scaled in psi; an external round gauge is available as an option, and gauge scales of MPa, psi or bar can be selected when ordering.
