The AirTAC GFR60020ALJC3T AirTAC Filter Regulator NPT3/4 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 GFR60020ALJC3T is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This size-600 unit is fitted with 3/4 in NPT ports, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, and a round pressure gauge reading in bar. It is the low-pressure regulator type, and the aluminium alloy bowl suits demanding size-600 installations. Maximum working pressure is 1.0 MPa (145 psi) and the operating 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 in to 1 in, standard or 5 um (W) filtration, differential-pressure, automatic or manual drains, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so ask us to confirm datasheet values 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.

On a beverage bottling line, the GFR60020ALJC3T filters carry-over water and particles from the plant air supply and holds a steady reduced pressure to the gripper and capper actuators, while the automatic drain keeps condensate out of the bowl without operator rounds.
In a warehouse conveyor system with 3/4 in air drops feeding diverters, pop-up transfers and stop gates, this filter regulator cleans the supply and stabilises cylinder pressure so divert timing stays repeatable, with the bar-scale round gauge giving operators a local pressure readout.
On a materials test rig or lab pilot line running at reduced supply pressure, the low-pressure type regulator in this unit sets the working pressure for instrument-grade air while the 40 um element and automatic drain protect downstream valves and sensors from water and debris.
Start with the port and size step: GFR units run from size 200 (1/8-1/4 in ports) through this size 600 (3/4 in), and the right step depends on the air demand of the circuit - we can check sizing against the published flow curves before you order. Drain choice matters: the automatic drain fitted here handles condensate removal on its own, while manual and differential-pressure drains are available on other codes. Filtration is the 40 um standard element here; specify the W code for 5 um where finer particulate capture is needed. This unit carries a round gauge on a bar scale; square embedded gauges and MPa or psi scales are alternatives. Thread is NPT here, with PT (standard) and G as order options, and this code is supplied without a mounting bracket. Because flow 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 GFR flow data as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your application details and we will confirm the relevant datasheet flow figures for this size-600, 3/4 in unit before you order.
The A in GFR60020ALJC3T means the bowl drain expels collected condensate automatically, so the unit does not rely on manual draining. Other GFR codes offer manual (M) or differential-pressure (blank) drains, and the bowl on this size-600 unit is aluminium alloy.
