The AirTAC GFR600C20AJNWTK 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 GFR600C20AJNWTK is a size-600 filter regulator: water and particulate filtration plus downstream pressure regulation combined in one body. This configuration carries NPT3/4 ports (NPT thread), a 5 um filter element (code W, finer than the 40 um standard), an automatic drain that expels collected condensate without manual attention, and a reverse/check valve that holds downstream pressure if the supply is interrupted. No gauge is fitted and no mounting bracket is included. The aluminium alloy bowl is standard at size 600. Maximum inlet pressure is 1.0 MPa (145 psi) and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi). Operating temperature is -5 to 70 C (non-freezing), medium is compressed air only.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8" to 1", a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge options, PT/G/NPT threads and bracket choices. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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.

Feeding the main air drop of a CNC cell, the 5 um element keeps swarf-laden, wet compressed air out of solenoid valves and actuators while the regulator holds a steady set pressure for clamping and tool-change circuits. The check valve holds the circuit if the shop compressor unloads.
On a bottling hall conveyor, cylinder-driven stops, pushers and diverters need clean, dry air at a stable pressure. The 3/4 in NPT connection serves the high-flow header, and the automatic drain clears condensate from the bowl without a operator stopping at the unit each shift.
Installed at the take-off point of a factory assembly hall's air header, the GFR600 filters bulk water and pipe-scale from the distribution main and regulates the branch pressure feeding workstations, with the automatic drain handling the heavy condensate load of a long header run.
Size and port set the capacity: the 600 body with NPT3/4 ports is the largest step in the GFR range, suited to high-consumption mains and headers; step down to 200/300/400 if your line draws less. Drain choice matters: automatic (this unit) suits unattended or hard-to-reach installations, manual suits supervised points, and the differential-pressure default drains on a pressure drop. Filter grade: 5 um (this unit) protects precision components; 40 um suits general upstream duty. Gauge, scale (MPa/psi/bar), thread (PT standard, G or NPT to order) and bracket are all selectable; this code specifies no gauge and no bracket.
Because published flow data is in curve form rather than a single rating, send us your application details and we will confirm sizing 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, not as a single rated number, so there is no one figure we can honestly quote. Send us your application details and we will confirm the relevant flow figures from the datasheet so you can size the unit correctly before ordering.
The code decodes it that way: A is the automatic drain, which ejects collected condensate on its own instead of waiting for a manual drain or a pressure drop, and N means no gauge is fitted. If you want local pressure indication, gauge options with MPa, psi or bar scales are available in the GFR range - ask us and we will quote the right variant.
