The AirTAC GFR60020ALC2 AirTAC Filter Regulator PT3/4 Low-Pressure 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 GFR60020ALC2 is an AirTAC GFR600 filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is the size 600 unit with 3/4 in PT ports, the low-pressure regulator type, a 40 um standard filter element, and an automatic drain that expels collected condensate without manual attention. The aluminium alloy bowl suits this large frame, and the fitted external round gauge reads in psi so operators can check and set line pressure at a glance. A mounting bracket is included for secure installation.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of port sizes, PT, G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um (W) filtration, standard or low-pressure regulation, gauge style and scale, and a reverse/check valve option. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

Feeding carton-sealing and case-erector cylinders on a packaging line, where filtered, moisture-reduced air at a stable low regulated pressure keeps actuator motion consistent through the shift.
Supplying workholding clamps on a CNC machining fixture, where the 40 um element protects the clamp valves from particulate and the low-pressure regulation holds the clamping force setting.
Driving diverter gates and stopper cylinders on a conveyor system, with the automatic drain clearing condensate in an area staff rarely visit and the round psi gauge letting maintenance verify set pressure.
Start with the size and port: the 600 frame with 3/4 in PT ports is the largest step in the GFR range, chosen when the line and the connected equipment demand the bigger bore. Choose the drain to match site practice - automatic drain (as here) suits unmanned or hard-to-reach installations, manual drain suits attended plants, and the differential-pressure default drains on a pressure drop. Pick 40 um for general air preparation or the 5 um W element where finer particulate removal matters. This unit carries the low-pressure regulator type; its exact adjustment range is not published, so confirm it with us against your set pressure. Gauge style and scale (round or square, MPa, psi or bar), thread (PT standard, G or NPT to order) and the included bracket complete the choices.
Because flow is published as curves rather than a single rated figure, we cannot quote one number here - send us your application details and we will confirm sizing against the datasheet before you order.
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 we do not quote one number. Tell us your line pressure, set pressure and the equipment you are feeding, and we will confirm the flow and full datasheet figures for this unit on request before you order.
The A in the code specifies the automatic drain, which expels collected condensate without anyone opening the bowl - useful on unmanned or hard-to-access installations. The GFR family is also available with a manual drain or the differential-pressure default drain, and this size 600 unit uses an aluminium alloy bowl.
