The AirTAC GFR600C20LJC3WTK 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 GFR600C20LJC3WTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body, with no lubricator. This 600-size unit carries a 3/4 in NPT port, a 5 um filter element (code W), a differential-pressure drain and a metal bowl - at size 600 the bowl is aluminium alloy. It is the low-pressure type, and this configuration includes a round pressure gauge with bar scale and a reverse (check) valve; no mounting bracket is fitted. Maximum working (inlet) 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 ports from 1/8 to 1 inch, and catalogue options for drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um), gauge style and scale (MPa, psi or bar), thread (PT standard; G and NPT to order), bracket and check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures - including the regulation range of this low-pressure type - 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.

Feeding clean, moisture- and particle-filtered, regulated air to tool-clamp and workholding circuits on a machining centre, with the 5 um element protecting sensitive clamping valves and the check valve holding downstream pressure if supply dips.
Conditioning the air feeding sealing, folding and carton-eject cylinders on a packaging line, where the filter-regulator keeps water and debris out of the valves and holds a steady low-pressure setting for consistent cylinder action.
Supplying regulated air to diverter gates, stoppers and pusher cylinders along a sorting conveyor, with the 3/4 in port serving a main drop and the differential-pressure drain shedding collected condensate during operation.
Size and port set the air capacity: 600 is the largest G-series size, and here it carries a 3/4 in NPT port - step between 200, 300, 400 and 600 if your circuit needs a different port. Filter grade is 5 um on this unit (40 um is the standard alternative); choose 5 um where downstream valves, cylinders or instruments need finer particle removal. Drain is differential-pressure on this configuration; automatic and manual drains are the other catalogue choices. The gauge fitted here is round with a bar scale; an embedded square gauge and MPa or psi scales are the other options. Thread is NPT on this unit - PT is the standard and G (BSPP) is also available to order. No mounting bracket is fitted; a bracket is optional. Flow is published as curves, not a single rated figure, so 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.
Flow for the GFR600 is published in the AirTAC catalogue as curves, not as a single rated figure, so we do not quote a number on the page. Tell us your supply pressure, port size and downstream demand and we will confirm the datasheet flow figures - and the regulation range of this low-pressure type - for this model on request.
The W in the code is AirTAC's 5 um filter grade, suited to downstream valves, cylinders and instruments that need finer particle removal than the 40 um catalogue standard. If your application does not need fine filtration, ask us about the 40 um version of the same 600-size filter regulator.
