The AirTAC GFR600C20ALJC3T AirTAC Filter Regulator NPT3/4 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 See datasheet ports, a differential-pressure 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 GFR600C20ALJC3T is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This 600-size unit has a 3/4 in NPT port, an automatic drain that ejects collected condensate without manual attention, and the standard 40 um filter element. It is the low-pressure regulator type, fitted with a round pressure gauge reading in bar, and supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The 600-size bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. The regulated output range for this low-pressure type is not published as a single figure; we confirm the range and the full datasheet 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.

On a woodworking or light-metal fixture line, the low-pressure regulator holds gentle clamp force on air cylinders while the 40 um element and automatic drain keep water out of the control valves.
Feeding a 3/4 in main air supply to a bottling or cartoning line, the unit filters and regulates air to actuated gates and grippers, with the automatic drain clearing condensate between shifts.
In a paint or coating booth, the low-pressure setting suits atomizing air delivered at reduced pressure, while the filter stage removes water and pipe scale before the air reaches the gun.
Size and port set the air capacity: the 600 size with its 3/4 in NPT port serves higher-flow lines than the 200/300/400 units, but flow is published as curves rather than a single rating, so ask us to confirm sizing against your application before ordering. Choose the drain to match your maintenance routine: automatic (this unit) clears condensate unattended, manual relies on operator action, and differential-pressure drains on a pressure drop. Filtration is 40 um standard; specify the W option for 5 um where finer protection is needed. The round gauge on this unit reads in bar; the embedded square gauge is the standard fitting, with MPa and psi scales also available. PT is the standard thread, with G and NPT as order options, and a mounting bracket can be specified if this no-bracket version does not suit your installation.
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 as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, downstream demand and acceptable pressure drop, and we will confirm the flow from the datasheet for this exact model.
The L in GFR600C20ALJC3T selects the low-pressure regulator variant rather than the standard type. Its exact regulated output range is not published in the material we hold, so we confirm the range from the AirTAC datasheet on request before you order.
