The AirTAC GFR600C20AC1T 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 GFR600C20AC1T is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 3/4 in NPT port, a 40 um standard filter element, an automatic drain that discharges collected condensate without manual attention, and a round pressure gauge with an MPa scale. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), the maximum working (inlet) pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). At size 600 the drain bowl 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 in to 1 in, a choice of differential-pressure, automatic or manual drain, a 5 um (code W) filter element option, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet 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.

Where a 3/4 in main drops air to a machining cell, this unit filters water and swarf-carrying particulate from the supply and holds a steady regulated pressure to the cell's air tools and clamps, with the automatic drain clearing condensate on its own.
Pneumatic cylinders and air-operated gates along a packaging or palletising conveyor behave consistently when supplied at a fixed pressure; this filter regulator conditions the 3/4 in branch line feeding those actuators and keeps moisture out of the valve stack.
Before air reaches solenoid valves, air cylinders and pneumatic logic on an automated machine, this unit cleans the supply and sets the working pressure shown on its round MPa gauge, protecting downstream components from water and overpressure.
Size and port are the first choice: the 600 frame with its 3/4 in NPT port suits lines that move more air than the 200/300/400 frames, but the right step depends on the flow your application needs. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. Other decodable choices: drain type (this unit is automatic; manual and differential-pressure drains are available), filter grade (40 um standard, 5 um with code W), gauge type and scale (this unit has an external round gauge on MPa; square embedded gauges and psi or bar scales are options), and thread (PT is the standard; G and NPT are catalogue options to order - this unit is ordered with NPT). A mounting bracket is included with GFR units.
Regulation range for this standard-type unit is 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drain. If your setpoint or inlet conditions sit near the limits, confirm the details with us 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 this family as performance curves, not as a single rated figure, so we do not quote a flow number. Tell us your application and we will confirm the relevant datasheet curve figures on request before you order.
The A in the code specifies an automatic drain, which discharges collected condensate from the bowl without anyone opening it - useful on lines that run unattended. The GFR family is also available with a manual drain or the differential-pressure drain (the catalogue default), and the drain choice also affects the regulator adjustment range: automatic and differential-pressure drains give 0.15-0.9 MPa (20-130 psi), while manual drain gives 0.05-0.9 MPa (7-130 psi).
