The AirTAC GFR600C20LJF3WTK AirTAC Filter Regulator NPT3/4 5um 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 GFR600C20LJF3WTK is an AirTAC GFR600 filter regulator: a water-and-particulate filter and a pressure regulator built into one body, so a single component both cleans the compressed air and holds downstream pressure where you set it. This size 600 unit is built around a 3/4 in NPT port and carries the W-coded 5 um filter element, a differential-pressure drain (the default drain option) and the low-pressure regulator type for circuits that work below mainstream line pressures. It comes with the embedded square gauge scaled in bar, a built-in check (reverse-flow) valve from the K code, the size 600 metal bowl (aluminium alloy at this size) and no mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working 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 in, PT (standard), G and NPT threads, 40 um standard or 5 um (W) filtration, differential-pressure, automatic or manual drains, standard or low-pressure regulation, gauge and scale choices, and an optional check valve. Rated flow for this series is published as curves rather than a single figure, so ask us and we will confirm the datasheet numbers 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.

At each tool drop feeding impact wrenches and nutrunners, this unit removes water and particles from the plant supply and holds a steady regulated pressure, so torque-controlled tools see consistent air on every cycle.
Pneumatic clamps on a machining centre need clean air and a pressure that stays put from first clamp to last. This filter regulator conditions the clamp circuit supply and keeps the set pressure stable while the fixtures cycle.
Carton-sealer and case-erector cylinders on a packaging line run all shift on shop air. This unit strips condensate and fine particles before they reach the valves and holds the cylinder pressure at the set point the line was tuned to.
Choose the size by port and flow: sizes 200 through 600 step up from 1/8 to 1 in ports and in the flow they carry; this unit is already the size 600 step with a 3/4 in NPT port. The W code fixes the 5 um element here - the blank code would give the 40 um standard element if general plant-air filtration suits the duty. The drain is the differential-pressure type; automatic (A) and manual (M) versions exist if you would rather have a positive auto drain or a hand-operated one. The gauge is the embedded square type scaled in bar (order scales are 1 = MPa, 2 = psi, 3 = bar), and the K code adds a check valve. Thread is NPT on this unit; PT is the standard catalogue thread and G is the other order option. Brackets are optional on this family and this configuration is ordered without one. Because flow is published as curves rather than a single rating, send us your pressure and flow conditions and we will confirm the right size from 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 GFR-series flow as curves rather than a single rated figure, so we do not quote one number. Tell us your working pressure and the flow your circuit needs, and we will confirm from the datasheet whether the GFR600 at 3/4 in NPT covers it before you order.
W is the 5 um filter element code. The standard GFR element is 40 um, which suits general plant air; this unit carries the finer 5 um element for circuits where downstream valves, cylinders or instruments need finer particle removal. If 40 um standard filtration is enough for your duty, the version without the W code is the matching choice.
