The AirTAC GFR600C20LJNWTK 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 GFR600C20LJNWTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This size-600 unit is built around a 3/4 in NPT port and carries the fine 5 um filter element (code W) instead of the standard 40 um grade, so it suits lines where tighter particle control matters. It is the low-pressure regulator type, drains its bowl by differential pressure (no manual draining routine), and a reverse/check valve is fitted. No gauge is supplied with this code and no mounting bracket is included. The size-600 bowl is aluminium alloy. 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 a choice of ports, PT/G/NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge options and bracket options. Because AirTAC publishes flow only as curves rather than a single rated figure, we confirm the datasheet and flow figures for your application on request - just ask before ordering.

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.

Feeds filtered, regulated air to the tool-change and clamping circuits of a CNC cell, with the 5 um element helping protect tight-tolerance pneumatic components from fine particles.
Sits at the drop point feeding cylinders and diverters on a carton or case-packing conveyor, holding a steady low set pressure so pick-and-place motions stay repeatable.
Conditions the air at a bench or test rig where instruments and small actuators need clean air at a controlled low pressure, with the check valve helping hold the downstream circuit.
Start with the port step: size 600 with a 3/4 in port is the largest GFR frame, so match it to your line size and the flow your system needs - and since flow is published as curves rather than one rating, ask us to confirm sizing against the application before ordering. This code is already fixed as the low-pressure regulator type with a 5 um element, differential-pressure drain, no gauge, a fitted reverse/check valve and no bracket; the standard alternatives in the family are the 40 um grade, automatic or manual drains, embedded square or optional external round gauges (MPa, psi or bar scales), and an included bracket. Thread is NPT here; PT is the standard catalogue thread and G (BSPP) is also an order option. If you need a gauge or a bracket on this unit, tell us and we will identify the correct code.
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, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and the flow your application needs and we will confirm the sizing from the datasheet on request.
This code is the low-pressure regulator type (code L), intended for circuits regulated below the standard type's range; the exact adjustment range for this variant is not published, so we confirm it on request. The W code also fits the fine 5 um filter element instead of the standard 40 um grade. The unit drains by differential pressure, has no gauge fitted, includes a reverse/check valve, and ships without a mounting bracket.
