The AirTAC GFR600C20AJC1WT 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 GFR600 combines water-and-particulate filtration with pressure regulation in a single body, so one 3/4 in (NPT) connection does both jobs. This configuration carries a 5 um filter element (the finer of the two published grades), an automatic drain that ejects collected condensate without operator attention, an aluminium alloy bowl, a round pressure gauge reading in MPa, and the standard regulator type with no reverse/check valve. It ships without a mounting bracket.
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um elements, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application.

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.

Filter and regulate the shop-air drop feeding a CNC machining centre's pneumatic tool-changer and clamps, with the 5 um element guarding spool valves and the automatic drain handling condensate on a line that runs unattended across shifts.
Condition the air feeding conveyor-mounted packaging cylinders and grippers at a single 3/4 in take-off, holding a steady regulated pressure so carton-sealing and case-packing strokes stay consistent while the automatic drain keeps the bowl clear.
Supply filtered, regulated air to spray-booth drops in a paint shop, where the 5 um element helps keep moisture and particulate out of the finishing air and the absence of a lubricator keeps oil mist away from the painted surface.
Start with port size: the 600 size steps up to 3/4 in ports for lines that feed larger actuators or multiple take-offs, while 200/300/400 sizes cover smaller drops; match the size to the flow your circuit needs. Then pick the drain: automatic (this unit) suits unattended or hard-to-reach installations, manual suits supervised points, and the differential-pressure default drains only when the pressure drop warrants it. Choose the 5 um element where downstream equipment tolerates less particulate, or the standard 40 um where coarser filtration is acceptable. Gauge choice is an embedded square gauge or an external round gauge, each available in MPa, psi or bar scales; this unit carries a round MPa gauge. Thread is PT as standard with G and NPT as order options - this unit is NPT. A bracket (omitted here, code J) is optional on GFR. Because flow is published as curves and not a single rated figure, 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 l/min, m3/h or SCFM number for this unit. Send us your application details and we will confirm the flow and datasheet figures for the GFR600 at 3/4 in on request.
This unit carries code A, the automatic drain, which discharges collected condensate by itself. It suits installations that run unattended or sit in awkward positions where a manual drain would be skipped. Manual and differential-pressure drain versions of the GFR600 are available if you prefer a different arrangement.
