The AirTAC GFR60020AC2GK 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 PT3/4" ports, a automatic 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 GFR60020AC2GK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 600-size unit is fitted with G3/4 ports, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, a round pressure gauge reading in psi, and a reverse/check valve that holds downstream pressure if the supply is interrupted. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options include manual or differential-pressure drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, G or NPT threads, and bracket choices. Flow is published as curves rather than a single rated figure, 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.

Filtering and regulating the plant air feeding a pneumatic press or forming machine at a 3/4-inch take-off, with the automatic drain handling condensate on a line that runs unattended through shifts.
Conditioning the air supply to packaging machinery cylinders and actuators, where the 40 um element protects valves from water and debris and the psi gauge lets operators set and verify working pressure.
Providing filtered, regulated air to a robotic or automated assembly cell, with the check valve holding downstream pressure during supply dips so fixtures and clamps do not release mid-cycle.
Size and port are the first decision: the 600 size with G3/4 ports suits lines with higher air demand, while smaller GFR sizes cover lighter circuits - match the port step to your piping and required flow. This unit carries the automatic drain, which suits unattended or hard-to-reach installations; manual and differential-pressure drains are available on other variants if you prefer operator control or supply-linked drainage. The 40 um element is the standard grade for general air preparation; specify the 5 um (W) option where finer protection is needed. The round gauge here reads in psi, and MPa or bar scales are alternatives. Threads come as PT (standard), G or NPT to order, and bracket options vary by variant.
Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering - we will supply the datasheet figures on request.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as curves rather than a single rated figure, so we do not quote one number. Ask us for the datasheet and we will confirm the flow figures for the GFR600 at your operating conditions before you order.
The A in the code GFR60020AC2GK means the bowl drains itself automatically, which suits installations that are not checked daily. GFR units are also available with manual drains or differential-pressure drains as the default, so you can select the drain style that matches your maintenance routine.
