The AirTAC GFR600C20LJF2WTK AirTAC Filter Regulator NPT3/4, 5 um 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 GFR600C20LJF2WTK 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 fine 5 um filter element (the standard element is 40 um; W selects 5 um), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the bowl is high enough, and the low-pressure regulator type for circuits that run below standard working pressures. The embedded square gauge reads in psi, a reverse/check valve is fitted to hold downstream pressure when the supply is removed, and the size-600 bowl is aluminium alloy. No mounting bracket is included with the J code.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and options for drain type, filter grade, gauge style and scale, thread (PT standard, G and NPT to order), bracket and reverse valve. Flow is published in the catalogue as curves rather than a single rated figure, so ask us and we will confirm the 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.

Point-of-use conditioning for a packaging machine section that runs on deliberately reduced air pressure: the 5 um element protects sealing and guiding components from water and fine debris while the low-pressure regulator holds the reduced setting the machine was set up for.
Installed at the 3/4 in drop feeding a machine cell or multi-circuit manifold, where one filter regulator conditions and sets pressure for the whole cell and the fitted check valve keeps the cell's circuits from dumping back toward the supply when the main valve closes.
Air conditioning for a test rig or laboratory pneumatic bench where instruments and actuators need clean, finely filtered air at a controlled reduced pressure, with the psi gauge giving the operator a direct local pressure readout at the bench.
Size 600 with a 3/4 in NPT port is the largest step in the GFR range, so the first selection decision is whether your line's air demand sits in the size-600 band or whether a smaller 200/300/400 unit at a smaller port would do; we can check that against the flow curves before you order. The 5 um element (W code) suits downstream equipment that needs finer filtration than the 40 um standard element provides. The differential-pressure drain needs no operator attention and no external signal, but if your compressors cycle lightly you may prefer an automatic-drain variant. The low-pressure regulator type (L) is chosen for circuits that run below standard working pressures; its exact adjustment range is not published in the sheet we work from, so confirm it with us. Gauge scale here is psi; MPa and bar scales exist as order options. Thread is NPT in this code, with PT standard and G available to order, and the J code means no mounting bracket is supplied. Flow is published as curves, not a single rating, so please 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 flow for the GFR600 series as curves, not as a single rated number, so we do not quote a figure that could mislead your sizing. Tell us your application and we will confirm the relevant datasheet flow figures on request before you order.
The W code selects the 5 um filter element instead of the 40 um standard element, for downstream equipment that needs finer filtration. The drain code is blank, which means the differential-pressure drain: condensate collected in the aluminium bowl is discharged automatically when the pressure differential across the bowl is sufficient, with no manual draining required.
