The AirTAC GFR600C20AJC2 AirTAC Filter Regulator PT3/4 Auto Drain 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 GFR600C20AJC2 is a size 600 filter regulator: a single body that removes water and particulate from compressed air and holds the downstream pressure at your set point. This configuration has a PT3/4 (3/4 in) port with PT thread, an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, and a round pressure gauge with a psi scale. The bowl at size 600 is aluminium alloy, and the standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi). No mounting bracket is fitted and no reverse/check valve is included.
This is a genuine AirTAC part. The GFR series is offered in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of PT, G (BSPP) or NPT thread, manual, automatic or differential-pressure drain, 40 um or 5 um (W) filtration, embedded square or external round gauges in MPa, psi or bar scales, and standard or low-pressure regulator types. Operating temperature 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.

On a bottling line, this 3/4 in filter regulator conditions the compressed air feeding gripper and pusher cylinders, removing water carried over from the compressor while holding a steady working pressure so bottle handling stays repeatable through the shift.
Installed at the main air drop serving a CNC machining cell, the unit knocks out condensate and pipe-scale particulate before air reaches tool-change and clamping circuits, with the psi gauge giving the operator a visible set point at the machine.
Mounted ahead of the valve manifold on a packaging conveyor, the filter regulator supplies clean, regulated air to the diverters and stopper actuators, while the automatic drain keeps the aluminium bowl clear of condensate on lines that run unattended.
Work size and port against the air demand of the circuit: the 600 size carries a PT3/4 (3/4 in) port, and moving up or down a size (200/300/400/600) changes both the port and the flow capacity shown in the catalogue curves. Choose the drain to suit access: automatic (this unit) suits installations that are not checked daily, manual suits attended points, and differential-pressure drain (the default) vents the bowl when the pressure drop across the element rises. The 40 um element is the standard grade; specify 5 um (code W) where finer particulate removal is needed. The round psi gauge fitted here is one option - an embedded square gauge is standard, and MPa, psi or bar scales can be ordered. PT is the standard thread; G (BSPP) and NPT are order options, and a bracket (code J omits it) can be added for panel or wall fixing.
Because flow is published as curves and not as a single rated number, 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 there is no one l/min or SCFM number we can honestly quote. Tell us your application and required flow, and we will confirm the sizing from the datasheet curves on request before you order.
The A in the code means the bowl drains itself: collected condensate is ejected automatically, which suits installations that are not inspected every day. The alternatives are manual drain (you open it yourself during checks) and the differential-pressure default (it vents when the element loads up). Note that with automatic or differential-pressure drain the regulation range is 0.15-0.9 MPa (20-130 psi); with manual drain it widens to 0.05-0.9 MPa (7-130 psi).
