The AirTAC GFR600C20ALF3WT AirTAC Filter Regulator NPT3/4 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 GFR600C20ALF3WT is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 3/4 in NPT port, an automatic drain that expels collected condensate without daily manual attention, and the fine 5 um filter element (code W) instead of the 40 um standard element. It is a low-pressure type regulator, fitted with an embedded square gauge reading in bar, and the size 600 bowl is aluminium alloy. A mounting bracket is included. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600, with port options, drain choices (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Because flow is published as curves rather than a single rating, we confirm the datasheet and flow figures for your application 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.

Conditioned air for the low-pressure pneumatic actuators on a bottling line's capper and diverter valves. The 5 um element keeps water and particulate away from valve seals, and the automatic drain clears condensate without a daily walk-round.
Air preparation ahead of a machining centre's low-pressure clamping and gate circuit. The embedded square bar gauge lets the setter verify the setpoint at the unit, and the aluminium alloy bowl stands up to shop-floor duty on the 600 size.
Filtered, regulated air for the stop and divert cylinders on a packaging conveyor. The automatic drain handles condensate in a damp compressor room, and the included bracket mounts the unit directly to the conveyor frame.
Step through the real choices before ordering. Size 600 with a 3/4 in port is the largest step in the GFR range - match it to your line size and required flow, and move down to 300 or 400 if your circuit is smaller. Drain: this unit is automatic (code A), which suits duty where nobody visits the unit daily; manual and differential-pressure drains are the other catalogue options. Filtration: the 5 um element (code W) is the finer choice; 40 um is the standard grade if your downstream components tolerate coarser air. Gauge: the embedded square gauge here reads in bar; MPa and psi scales and an external round gauge are available. Thread: PT is the standard; G and NPT are order options, and this unit is specified NPT. A bracket is included.
One honest note on sizing: AirTAC publishes flow as curves, not as a single rated figure, so we do not quote a number here. Ask us to confirm sizing against your application and we will read it from 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 the GFR series as curves rather than a single rated figure, so we do not quote a number on the page. Tell us your application and we will confirm the flow figures from the datasheet on request before you order.
In this code, A is the automatic drain - the bowl ejects collected condensate on its own, so no manual draining routine is needed - and W is the 5 um filter element, one grade finer than the 40 um standard. If your downstream components tolerate coarser air, the 40 um version is the alternative catalogue choice; ask us and we will decode the equivalent model.
