The AirTAC GFR600C20C3T 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 GFR600C20C3T is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 600-size unit is fitted with a 3/4 in NPT port, a 40 um filter element, a differential-pressure drain and a round pressure gauge reading in bar. Maximum inlet pressure is 1.0 MPa (145 psi), the regulating range is 0.15-0.9 MPa (20-130 psi), and the operating temperature is -5 to 70 C (non-freezing). The bowl on this size is aluminium alloy.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and with manual, automatic or differential-pressure drains, 40 um standard or 5 um (W) 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 rating, so ask us to 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.

Point-of-use conditioning on the air drop feeding a CNC machining centre: water and swarf-laden particulate are stripped out before the machine's valves, and the regulator holds a steady setting for clamps and tool changers.
Conditioning the supply to cylinders and air-driven grippers on a cartoning or bottling conveyor line, where clean, dry air and a stable pressure setting keep pick-and-place motion repeatable through the shift.
A 3/4 in take-off from the main plant air header feeding a production bay: the filter stage protects downstream equipment from condensate and pipe scale while the regulator sets the bay's working pressure.
Choose the size and port step (200 through 600, 1/8 to 1 in) against the flow your line needs - the larger the size, the larger the port and the flow capacity. Drain choice matters: differential-pressure (this unit) discharges condensate as the pressure drop across the element rises, automatic drains continuously, and manual drains only when operated. Filter grade is 40 um standard or 5 um with code W for finer protection. The gauge can be the embedded square type or an external round gauge, scaled in MPa, psi or bar - this unit carries a round gauge reading in bar. Thread is PT as standard, with G (BSPP) and NPT as order options; this unit is NPT. Flow is published as curves, not a single rated figure, so 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 figure, so we do not quote one number. Tell us your application and we will confirm the datasheet flow curve and correct sizing for you before you order.
The differential-pressure drain (the default on this unit) discharges collected condensate when the pressure drop across the filter element rises. Automatic (code A) and manual (code M) drains are available as order options across the GFR family.
