The AirTAC GFR600C20AJC3TK 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 GFR600C20AJC3TK is an AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation in a single body. This configuration is built around a 3/4 in NPT port, with a 40 um standard filter element and an automatic drain that bleeds condensate from the bowl without manual attention. The 600-size bowl is aluminium alloy, an external round gauge scaled in bar is fitted, and a reverse/check valve is included. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). No mounting bracket is supplied with this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options include manual or differential-pressure drains, a 5 um element (code W), square or round gauges scaled in MPa, psi or bar, G or NPT threads, brackets and a reverse/check valve. 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.

Point-of-use conditioning on the 3/4 in header feeding a CNC machining cell: the 40 um element strips water and swarf-carrying particulate before the regulator sets a steady supply pressure to fixtures, clamps and tool-change actuators, while the automatic drain keeps condensate off the bowl floor without operator rounds.
A main air drop on a bottling or cartoning line where case packers, diverters and conveyor stop gates run continuously. The filter regulator gives the line a single set-and-lock pressure, the check valve holds the circuit against backflow, and the automatic drain suits a drop that nobody opens during a shift.
Conditioning at the take-off of a factory ring main serving multiple workstations. The 600-size body and 3/4 in port handle a branch feeding several downstream points, the bar-scaled round gauge gives maintenance staff a readable setpoint, and the aluminium 600 bowl stands up to a shared plant environment.
Start with the port step: this unit is size 600 with a 3/4 in NPT port, the largest in the GFR range, so match it to the pipe size and air demand of the line it feeds. Choose the drain to suit access: automatic (this code) suits unmanned or hard-to-reach installations, manual suits attended stations, and the default differential-pressure drain tracks flow. Filter grade is 40 um as standard here; specify 5 um (code W) only where downstream equipment needs finer filtration. The fitted round gauge reads in bar; embedded square gauges and MPa or psi scales are alternatives. PT is the standard thread, with G (BSPP) and NPT as order options, and brackets are optional (this code omits the bracket).
One honest note before you order: AirTAC publishes flow for this family as curves, not as a single rated number, so send us your flow and pressure requirements and we will confirm sizing against the datasheet before you commit.
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 family as performance curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Send us your required flow and working pressure and we will confirm the sizing against the datasheet on request before you order.
The A in the code GFR600C20AJC3TK selects the automatic drain, which expels collected condensate from the bowl without manual attention - the right choice for unattended or hard-to-reach installations. The GFR family also offers a manual drain (code M) and the differential-pressure drain as the default, so specify the code that matches how often the bowl can be serviced.
