The AirTAC GFR600C20AJF1WT 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 GFR600 combines water and particulate filtration with pressure regulation in a single body. This GFR600C20AJF1WT is built for 3/4 in NPT threads, filters to 5 um (the finer of the two published grades), drains condensate automatically, and carries an embedded square gauge scaled in MPa. Its regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and it operates from -5 to 70 C in non-freezing conditions. At size 600 the bowl is aluminium alloy, and this configuration is supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options including manual or differential-pressure drains, a 40 um standard element, alternate gauge scales (psi or bar), G (BSPP) or NPT threads, a reverse/check valve, and a mounting bracket. Published flow data for this series is given as curves rather than a single rating, so ask us to confirm the figures for your application and we will supply the datasheet 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 filtration and regulation for the 3/4 in air feed serving a CNC machining centre's clamps, tool-change cylinders and blow-off, with the 5 um element protecting downstream valves from fine particulate.
Conditioning the compressed air that drives conveyor stops, pushers and gating cylinders on a bottling line, holding a steady regulated pressure while the automatic drain clears condensate carried in from the ring main.
Filtered and regulated air for pneumatic torque tools and press fixtures at an automotive assembly station, with the MPa-scaled square gauge giving operators a local setpoint reference at the workstation.
Start with the port step: size 600 with 3/4 in NPT threads suits lines whose demand sits at the top of the GFR range, and stepping down to 400, 300 or 200 reduces both port and capacity - confirm the match against the published flow curves before ordering. This unit already carries the automatic drain, the 5 um element (the 40 um standard grade is the alternative), a square MPa gauge, and no bracket; if you would rather drain by hand or by differential pressure, read the gauge in psi or bar, thread in PT or G, or mount on a bracket, those are the codes to choose instead. Because AirTAC publishes flow 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 operating pressure and air demand and we will confirm the flow from the datasheet on request before you order.
The A in this code specifies the automatic drain, which expels collected condensate without operator attention - useful on lines that run unattended. The same GFR600 body is also catalogued with a manual drain or the differential-pressure (blank) drain, and the regulator adjustment range differs by drain type: 0.15-0.9 MPa (20-130 psi) applies to this automatic-drain version.
