The AirTAC GFR600C20LC2WTK 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 AirTAC GFR600C20LC2WTK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built for a 3/4 in NPT port, carries the W fine-filtration element (5 um instead of the standard 40 um), and is the low-pressure regulator type for circuits that run at reduced set pressures. The differential-pressure drain bleeds accumulated condensate automatically whenever the pressure differential across the bowl is sufficient, and a reverse/check valve is fitted to hold downstream pressure if the supply is interrupted. The 600-size bowl is aluminium alloy, and this unit comes with an external round gauge on a psi scale plus the mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, standard or low-pressure regulation, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing figures from the datasheet for your application 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 clean, finely filtered and regulated air to the seal and clamp cylinders on a packaging line, with the low-pressure type regulator holding a reduced set point and the check valve holding position if plant air drops.
Supplies regulated air to diverters, stoppers and lift gates along a conveyor system, where the 5 um element protects the directional valves from particulate and the differential-pressure drain keeps condensate out of the circuit.
Prepares air for clamping fixtures and light pneumatic presses on a machining cell, delivering fine-filtered air at a stable low set pressure with a psi gauge the operators can read directly.
Step up or down through the GFR sizes (200/300/400/600) against the flow your line needs - the 600 size is the largest, with a 3/4 in port here in NPT (PT is the standard thread; G and NPT are order options). Choose the 5 um W element when downstream equipment - precision valves, cylinders with tight clearances, instrumentation - needs finer filtration than the 40 um standard element provides. This unit is the low-pressure regulator type, intended for circuits set well below full line pressure; the exact adjustment range for the low-pressure type is not published, so confirm it with us against your set point. Drain is differential-pressure (automatic bleed on pressure differential); automatic (A) and manual (M) drains are alternatives in the family. Gauge here is the external round type on a psi scale; embedded square gauges and MPa/bar scales are the other options. A mounting bracket is included, and the K code means a reverse/check valve is fitted. Because flow is published as curves, not a single rating, 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 GFR series as curves rather than a single rated figure, so we do not quote a rated flow number. Tell us your operating pressure and the flow your application needs, and we will confirm the sizing from the datasheet curves on request before you order.
The W code selects the 5 um filtration element instead of the 40 um standard element, for finer removal of particulate ahead of sensitive downstream equipment. The L code makes this the low-pressure regulator type, intended for circuits set below full line pressure; its exact adjustment range is not published, so confirm it with us against your set point.
