The AirTAC GFR600C20ALJF3T 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 GFR600C20ALJF3T is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size-600 unit is built for a 3/4 in NPT port, with an automatic drain that discharges collected condensate without manual attention, a 40 um standard filter element, and the low-pressure regulator type. The embedded square gauge reads in bar, the bowl is aluminium alloy at this size, and no mounting bracket is fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), an optional 5 um element, gauge scale options, and G(BSPP) or NPT thread variants to order. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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. 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.

Paint-line drops need clean, pressure-controlled air at the gun. This unit filters water and particulate and regulates in one body, and the low-pressure regulator type suits finishing work where a steady, moderate set pressure matters.
Carton taping and sealing heads run on small pneumatic cylinders that need clean air and a stable, lower set pressure. This unit filters and regulates at the line drop, and the automatic drain keeps condensate out of the machine.
Bench rigs that exercise actuators and valves benefit from one body doing both jobs: particulate and water removal ahead of a low-pressure regulation stage, with a bar-scale square gauge for direct readout at the bench.
The real choices on this family are decodable from the code: size 200/300/400/600 sets the port and flow capacity, so step up a size when your line needs more air; drain type is differential-pressure by default, with automatic (as here) or manual to order; the element is 40 um standard or 5 um with code W for finer protection; the gauge can be the embedded square type or an external round gauge, scaled in MPa, psi or bar; thread is PT as standard with G and NPT as order options; and a bracket is optional. Flow is published as curves, not a single rating, so 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, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and datasheet figures for this exact configuration on request.
The automatic drain (code A) discharges collected condensate by itself, which suits unattended or hard-to-reach installations. The GFR family is also available with the default differential-pressure drain or a manual drain - just ask for the equivalent code when ordering.
