The AirTAC GFR600C20ALJC1WT AirTAC 3/4 in NPT Filter Regulator 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 AirTAC GFR600C20ALJC1WT 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 3/4 in NPT port, a 5 um filter element (the finer of the two published grades), an automatic drain that ejects collected condensate without manual attention, and a round pressure gauge reading in MPa. It is the low-pressure regulator type, is supplied without a mounting bracket, and has no reverse/check valve fitted. At size 600 the bowl is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part, sold by an authorised distributor. The GFR family spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT (standard), G or NPT threads, manual, automatic or differential-pressure drains, 40 um or 5 um elements, and square or round gauges in MPa, psi or bar scales. Because AirTAC publishes flow only as curves rather than a single rated figure, we confirm flow and datasheet 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. 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.

Feeding filtered, regulated air to spray guns and atomising stations on a finishing line, where the 5 um element helps keep water and particulate out of the finish and the automatic drain clears condensate between shifts.
Conditioning the air feeding cylinders and actuators on a cartoning or case-packing conveyor, giving the machine one point of filtration and pressure control at the 3/4 in drop.
Supplying regulated air to bench-top automation, sample handling and test-rig panels, where the low-pressure regulator type and round MPa gauge suit lower set pressures and local monitoring.
Size and port set the capacity of the unit: the 600 size with its 3/4 in port is the largest step in the GFR range, so move up or down (200/300/400/600) to match the line size. Drain type is a real choice here: automatic (as fitted) drains itself, manual needs operator attention, and differential-pressure drain is the default on other variants. Filter grade is 40 um standard or 5 um (this unit, code W) where finer particulate removal is wanted. Gauge choices are the embedded square gauge or the external round gauge fitted here, in MPa, psi or bar scales. Thread is PT as standard, with G (BSPP) and NPT (this unit) as catalogue options to order; a mounting bracket can be added if the J (no bracket) option does not suit. Note this is the low-pressure regulator type, so confirm the adjustment range suits your set pressure before ordering. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application 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 this family 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 flow and datasheet figures for this exact model on request.
The code decodes as follows: A is the automatic drain, which ejects collected condensate without manual attention (manual and differential-pressure drains are the other catalogue choices), and W is the 5 um filter element, the finer alternative to the 40 um standard grade. The C1 gauge is the external round gauge reading in MPa, and the trailing T is the NPT thread option.
