The AirTAC GFR600C20AF3WT AirTAC Filter Regulator NPT3/4, 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 GFR600C20AF3WT is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a 3/4 in NPT port, a 5 um filter element (the tighter of the two published grades), an automatic drain that expels collected condensate without manual attention, and an embedded square gauge reading in bar. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) with this automatic-drain version, maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). At size 600 the metal bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and is ordered with a choice of drain type, filter grade, gauge scale, thread form and bracket option. We do not quote a single rated flow figure because the catalogue publishes flow as curves; ask us and we will confirm the datasheet and sizing figures for your application on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.

Point-of-use conditioning for a CNC machining centre: the 5 um element strips water and swarf-carrying particulate before it reaches solenoid valves and spindle-clamp cylinders, while the regulator holds a steady setting for clamping repeatability.
Filtered, regulated air for the pneumatic actuators on a bottling and capping line. The automatic drain handles condensate through continuous shifts without an operator having to bleed the bowl, and the bar-scale gauge gives a local pressure reference at the machine.
A drop at an automotive assembly station feeding impact wrenches and air ratchets: the filter-regulator keeps supply pressure stable at the tool panel and the 3/4 in port suits a high-draw tool manifold on the main air ring.
Size and port set the capacity ceiling: GFR600 is the largest G-series size, here with a 3/4 in NPT port, so step up or down (200/300/400/600) against the flow your line actually needs. Choose the drain to match the installation: automatic (this unit) suits unattended duty, manual suits periodic checks, and the differential-pressure default drains only when the pressure differential demands it. Filter grade is 40 um standard or 5 um (code W, as fitted here) where finer particulate removal matters. The square gauge is embedded as standard with MPa, psi or bar scales, an external round gauge is optional, and thread is PT as the catalogue standard with G and NPT as order options. A mounting bracket is included on this configuration.
Because flow is published as curves rather than a single rating, 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 the GFR series as curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure, downstream pressure setting and expected air demand, and we will confirm the datasheet flow curve and check the sizing for your application on request.
In GFR600C20AF3WT, A is the drain code: this unit has an automatic drain that expels collected condensate on its own instead of the differential-pressure default or a manual drain. W is the filter grade code: a 5 um element is fitted instead of the 40 um standard. With the automatic drain, the regulator adjustment range is 0.15-0.9 MPa (20-130 psi).
