The AirTAC GFR600C20AC3TK AirTAC Filter Regulator NPT3/4 with Gauge 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 GFR600C20AC3TK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body, so you clean and control the air with a single component and one bowl to service. This configuration is fitted with an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, a round pressure gauge reading in bar, and a reverse/check valve that holds downstream pressure if the upstream supply is lost. The 3/4 in NPT thread suits larger distribution lines feeding multiple actuators or valves.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with a choice of ports, drain types, 40 um or 5 um filtration, gauge styles and scales, and G/NPT thread options. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range with automatic drain is 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rated figure, 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.

Installed at the 3/4 in drop feeding a packaging machine's valve manifold, it cleans the plant air and sets a stable working pressure for the carton-forming and sealing cylinders, while the automatic drain keeps condensate off the valves on a line that runs unattended shifts.
Mounted where the 3/4 in branch supplies conveyor gate and stopper cylinders, it filters scale and pipe debris out of the air and holds the pressure the gate actuators were sized for, with the check valve holding the setting through brief upstream pressure dips.
Used at a distribution tee that feeds several downstream FRL panels or machine stations, it provides one filtered, regulated 3/4 in supply point, with the bar-reading gauge giving operators a local reference for the header pressure they have set.
Start with the port step: this unit is size 600 with a 3/4 in NPT thread, the largest port in the GFR range, so choose it when your line is 3/4 in and your flow demand is at the top of what the series serves - match the published flow curve to your consumption rather than assuming. Drain type is a real choice: automatic (this unit) suits points you cannot visit often; manual suits attended stations; differential-pressure drain is the default. Filtration is 40 um standard here; specify the W variant if you need 5 um. The round gauge reads in bar; embedded square gauges and MPa/psi scales are alternatives. PT is the standard thread and G/NPT are order options - state your thread when ordering. A bracket is included; J variants omit it. Because flow is published as curves and not a single rating, 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, not as a single rated figure, so we do not quote a l/min, m3/h or SCFM number. Tell us your operating pressure and air consumption and we will confirm the flow figures from the datasheet for this exact model before you order.
In the code GFR600C20AC3TK, A is the automatic drain, which ejects collected condensate by itself instead of waiting for a manual bowl drain, and K is the fitted reverse/check valve, which helps hold downstream pressure if the upstream supply drops. Both are decodable options on GFR units; manual drain and no check valve are the alternatives.
