The AirTAC GFR600C20AF2G AirTAC Filter Regulator G3/4 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 GFR600C20AF2G is a filter regulator in the GFR600 series: it removes water and particulate from compressed air and holds downstream pressure steady, in a single body. This unit is built around a G3/4 (3/4 in) port with G (BSPP) thread, carries the standard 40 um filter element, and drains condensate automatically, so it suits lines that run unattended. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), an embedded square gauge with a psi scale shows the setpoint, and the 600 size takes an aluminium alloy bowl. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
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 a 5 um filter element (code W), manual or differential-pressure drains, MPa or bar gauge scales, an external round gauge, and PT or NPT threads in place of G. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application before ordering.

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.

Filtered, regulated air for gripper and cylinder actuators on a beverage bottling line, with the automatic drain clearing condensate through continuous shifts.
Stable downstream pressure for pneumatic tape heads and box pushers on a packaging conveyor, with the 40 um element holding back pipe scale and rust.
Point-of-use regulation for pneumatic valves on laboratory automation skids, with the local psi gauge giving operators a direct setpoint readout.
The first choice is size and port: 200, 300, 400 and 600 step up in port diameter and flow capacity, and this model sits at the top with G3/4. Match the size to your air demand, then confirm it - flow is published as curves, not a single rating, so send us your flow and pressure requirements and we will check the datasheet with you before you order. Drain type is a real decision: automatic (this model, code A) ejects condensate without attention, manual needs an operator, and differential-pressure (the default) discharges as the element loads up. Filter grade is 40 um standard or 5 um with code W where downstream equipment needs finer protection. The gauge can be ordered with MPa, psi or bar scales, and threads come as PT (the standard), G or NPT. A mounting bracket is included with this unit.
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 G-series flow as curves rather than a single rated figure, so we do not quote one number. Tell us your required flow and working pressure and we will confirm the figures from the GFR600 datasheet on request before you order.
It specifies the automatic drain: the bowl ejects collected condensate on its own, which suits unattended or continuously running lines. The alternatives are a manual drain you operate yourself and a differential-pressure drain (the default) that discharges as the element loads. The regulator adjustment range also depends on drain type: 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drains, and 0.05-0.9 MPa (7-130 psi) with a manual drain.
