The AirTAC AirTAC GFR600C20AC3WT 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 GFR600C20AC3WT is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built around a 3/4 in NPT port, a 5 um filtration element (the finer of the two catalogue grades), an automatic drain that expels collected condensate without manual attention, and a round pressure gauge reading in bar. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the maximum working (inlet) pressure is 1.0 MPa (145 psi). At size 600 the bowl is aluminium alloy, and the unit operates in temperatures from -5 to 70 C (non-freezing). A mounting bracket is included.
This is a genuine AirTAC part. The GFR filter-regulator line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and is available with differential-pressure, automatic or manual drains, 40 um or 5 um filtration, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing figures for your application 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.

Installed at the 3/4 in air drop feeding a CNC machining cell, the unit filters water and swarf-laden particulate down to 5 um and holds a steady regulated supply pressure to the cell's valves and actuators, with the automatic drain handling condensate without daily attention.
Mounted on the supply line serving pneumatic conveyor diverters and stop-gate cylinders in a packaging hall, the regulator keeps actuator pressure consistent across shift changes while the automatic drain clears moisture in a wet compressor room.
Fitted ahead of laboratory automation and test-rig manifolds that are sensitive to both particles and pressure drift, the 5 um element and bar-reading gauge give technicians clean air and a visible, repeatable set pressure.
Size and port are the first choice: the 600 frame with its 3/4 in NPT port suits lines with substantial air demand, while smaller 200/300/400 frames cover lighter circuits - step up a size when in doubt, since flow is published as curves rather than a single rating. Drain type is a real decision here: this unit carries the automatic drain, which suits unattended or hard-to-reach installations; differential-pressure (default) and manual drains are the alternatives. Filtration grade is 5 um on this model (code W) against the 40 um standard - choose 5 um where downstream valves, cylinders or instruments need finer protection. The gauge on this configuration is the external round type reading in bar; embedded square gauges and MPa or psi scales are the other catalogue options. Thread is NPT here, with PT as the standard and G (BSPP) also orderable, and a mounting bracket is included.
Because AirTAC publishes flow only as curves and not as a single rated number, we do not quote a flow figure here. Send us your application details and we will confirm the 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 flow number here. Tell us your inlet pressure, set pressure and expected air demand, and we will confirm the sizing from the datasheet on request before you order.
The drain is the part that removes condensate collected in the bowl. This configuration carries the automatic drain (code A), which ejects condensate by itself and suits unattended or hard-to-reach installations. The catalogue alternatives are the differential-pressure drain (the default) and the manual drain, and the drain type also affects the regulator's adjustment range: with an automatic drain the range is 0.15-0.9 MPa (20-130 psi).
