The AirTAC GFR60020ALJC2 AirTAC Low-Pressure Filter Regulator PT3/4 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 GFR60020ALJC2 is a GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at a set point. This size-600 unit is built for 3/4 in PT ports, and this configuration carries an automatic drain that expels collected condensate without operator attention, 40 um standard filtration, the low-pressure regulator type, an external round gauge on a psi scale, and an aluminium alloy bowl. No mounting bracket is included and no reverse/check valve is fitted. 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 port sizes from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), a 5 um filter option (code W), gauge and thread options (PT standard; G and NPT to order), and standard or low-pressure regulator types. Because flow is published as curves rather than a single rating, we confirm datasheet and sizing 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. 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 wrapper and cartoner cylinders on a food-plant packaging line: the 40 um element strips water and pipe scale before they reach the valve bank, while the low-pressure regulator holds the reduced pressure the actuators were set up for.
Conditioning the pilot-air circuit of a workshop pneumatic press: the automatic drain clears condensate from the aluminium bowl without an operator, and the regulator keeps control-valve supply steady as the plant compressor cycles.
Supplying divert and stopper cylinders on a distribution-centre conveyor sorter: the 3/4 in PT connection suits a main branch line, and the round psi gauge lets maintenance verify set pressure at a glance during shift checks.
Choices that matter on this series: step up or down in size (200/300/400/600) to match the port and the flow your line needs - the 600 size here is the largest, with a 3/4 in PT connection. Drain type is a real decision: automatic (as fitted here) empties the bowl without operator input, manual needs a push, and the differential-pressure default drains only when the pressure drop warrants it. Filtration is 40 um standard; specify code W for 5 um where downstream equipment needs finer air. On gauges, this unit carries an external round gauge on a psi scale; an embedded square gauge with MPa/psi/bar scales is the catalogue alternative. Thread: PT is the standard; G (BSPP) and NPT are order options. The low-pressure regulator type in this code has an adjustment range that is not published, so ask us to confirm it against your set point before ordering. Flow is published as curves, not a single rating, so send us your flow requirement and we will confirm sizing from the datasheet.
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 a number. Send us your required flow and line conditions and we will confirm sizing from the datasheet on request.
The A in the code specifies an automatic drain, which expels collected condensate from the aluminium alloy bowl without operator input. The same size is also available with a manual drain or the differential-pressure default - tell us your preference when ordering. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
