The AirTAC GFR60020ALF2G AirTAC Filter Regulator G3/4 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 AirTAC GFR60020ALF2G is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a G3/4 (BSPP) port, an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, and a low-pressure regulator type for circuits that run at reduced setpoints. The embedded square gauge is fitted with a psi scale, and the size-600 bowl is aluminium alloy. A mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with a choice of ports, threads (PT standard; G and NPT as order options), drain types, 40 um or 5 um elements, gauge scales and low-pressure or standard regulator types. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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. 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.

Feeds filtered, regulated air at a reduced setpoint to carton-sealing and wrapping heads on a packaging line, with the automatic drain keeping condensate off the valves between shifts.
Serves as the point-of-entry prep unit for a low-pressure clamping or forming station, protecting downstream cylinders while holding the working pressure the tooling was set up for.
Mounted at the machine's 3/4 in air inlet, it strips water and 40 um particulate from the shop supply and regulates it before the machine's manifold of directional valves.
Start with the port step: size 600 with a 3/4 in port suits lines whose air demand sits at the top of the G-series range, and stepping up a size reduces restriction at a given demand. Choose the drain to match access: automatic (as here) for unattended duty, manual where you prefer a controlled blowdown, or the differential-pressure default. Pick the element grade - 40 um standard for general air prep, 5 um (code W) where finer protection matters. Select the gauge scale (MPa, psi or bar) and thread (PT standard, G or NPT to order); a bracket is included on this unit. Because flow for the GFR series is published as curves rather than a single rated figure, 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, not as a single rated figure, so we do not quote a number here. Tell us your inlet pressure, setpoint and air demand and we will confirm the sizing from the datasheet on request.
The A in the code specifies an automatic drain, which ejects collected condensate on its own - useful where the unit is mounted in a hard-to-reach spot. The GFR family is also available with a manual drain or with the differential-pressure default drain; the filter grade (40 um standard, 5 um with code W) can be chosen the same way.
