The AirTAC GFR600C20AC1WT AirTAC Filter Regulator 3/4 in NPT 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 GFR600C20AC1WT is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in one body. This configuration is sized with a 3/4 in NPT port, carries the 5 um filter element (code W) in place of the 40 um standard, drains condensate automatically, and is fitted with the external round gauge on the MPa scale. The bowl on this 600 size is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 in, and options including manual or differential-pressure drains, the 40 um standard element, embedded square or optional external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. We confirm flow and datasheet figures on request - flow is published as curves rather than a single rating.

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 the air feeding a paint line's spray-booth drops: the 5 um element catches fine particulate before it reaches the finishing work, while the regulator holds a steady set pressure to the spray guns.
Supplying filtered, regulated air to the cylinders and grippers on a carton-sealing conveyor, with the automatic drain clearing collected condensate so the line runs unattended through a shift.
Feeding filtered, regulated air to pneumatically actuated valves on a treatment-plant skid, with the round MPa gauge giving operators a clear local reading of the set pressure.
Step up through sizes 200, 300, 400 and 600 to match port and flow demand; this unit sits at the 600 size with a 3/4 in NPT port. Choose the drain to suit the installation: automatic (as here) for unattended duty, manual where an operator drains on schedule, or the differential-pressure default. Pick 40 um for general protection or 5 um (this unit, code W) where finer filtration matters. An embedded square gauge is standard with an optional external round gauge in MPa, psi or bar scales; this unit carries the round gauge on the MPa scale. Thread is PT as standard with G and NPT as orderable options - this unit is NPT. A mounting bracket is included. Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering.
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 number, so we do not quote a rated flow figure. Tell us your application and we will confirm the flow and datasheet figures for this 3/4 in unit on request.
This unit is code A: an automatic drain expels collected condensate without operator attention. The GFR series is also available with a manual drain or the differential-pressure default, and with the 40 um standard element instead of the 5 um element fitted here.
