The AirTAC GFR600C20ANWTK 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 GFR600C20ANWTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size-600 unit is specified with a 3/4 in NPT port, 5 um filtration (the W grade, finer than the 40 um standard element), an automatic drain that expels collected condensate without manual attention, and a reverse/check valve fitted. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi) and a maximum inlet pressure of 1.0 MPa (145 psi). At size 600 the bowl is aluminium alloy, and the unit is supplied without a gauge.
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of drain types, 40 um or 5 um filtration, gauge options and PT, G or NPT threads. Flow for this series is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

Conditioning and regulating the shop-air feed that runs tool changers, clamps and chip-clearing jets on a machining centre, with 5 um filtration protecting the finer valve internals.
Filtering and setting a stable supply pressure for the cylinders and grippers on a carton-forming and sealing conveyor, with the automatic drain handling condensate on an unattended line.
Cleaning and regulating air at the drop to spray stations and air motors in a paint shop, where the 5 um element and automatic drain help keep water and debris out of the finishing equipment.
Choose the size by the port and flow step your line needs: 200 through 600 cover 1/8 in to 1 in, and this 600 unit sits at the top of the range with a 3/4 in NPT port. Pick the drain to suit access: automatic (as here) where the unit is hard to reach, manual where you want controlled blow-down, or the differential-pressure default. Select 5 um filtration where downstream equipment needs finer air than the 40 um standard element, and decide whether you want a gauge fitted and on which scale. PT is the standard thread; G and NPT are order options, as is the bracket. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application 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 application and we will confirm the flow and datasheet figures for this 3/4 in NPT, 5 um, automatic-drain unit on request before you order.
The A in the code specifies an automatic drain, which expels collected condensate on its own - useful where the bowl is mounted out of easy reach. The N specifies that no gauge is fitted; gauge options with different scales are available in the GFR family if you want a pressure indication at the regulator.
