The AirTAC GFR600C20LC3WTK 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 GFR600C20LC3WTK is a size-600 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built for 3/4 inch NPT ports, carries a 5 um filter element for finer filtration than the 40 um standard, and uses a differential-pressure drain that bleeds condensate automatically whenever the pressure differential across the element is high enough - no daily manual draining. It is a low-pressure regulator type fitted with a round bar-scale gauge and a reverse/check valve, and the size-600 bowl is aluminium alloy.
This is a genuine AirTAC part from the GFR filter-regulator line, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 inch up to 1 inch, a choice of drain types, 40 um or 5 um filtration, gauge styles and scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

Feeding a workshop air ring main that supplies pneumatic presses: the 5 um element and regulation protect valve stacks and cylinders on the press line, while the differential-pressure drain keeps condensate off the tools.
Conditioning air for grippers and diverters on a carton packaging conveyor, where the low-pressure regulator type holds a gentle working pressure for delicate clamp actuation and the check valve holds the circuit if supply dips.
Supplying bench-scale lab automation and test-rig actuators from a house air drop, where the 5 um grade, bar-scale gauge and included bracket give a tidy, readable wall-mounted conditioning point.
Size 600 with a 3/4 inch NPT port is the right step when your line flow sits above what the 400 frame serves; match the frame to the flow curve rather than to pipe size alone. The 5 um element (code W) suits downstream equipment that tolerates less particulate than the 40 um standard protects. The differential-pressure drain needs no operator attention, but if your duty cycle is light, ask whether a manual or automatic drain suits better. The round gauge here reads in bar; square embedded gauges and MPa or psi scales are also available. A reverse/check valve is fitted, and the mounting bracket is included.
Because flow is published as curves and not a single rated figure, send us your application details and we will confirm sizing and 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 flow for the GFR series as curves, not as a single rated number, so we do not quote a figure here. Send us your line pressure, downstream pressure target and expected air demand, and we will confirm the sizing and datasheet figures for this exact model on request.
A differential-pressure drain opens to eject collected condensate when the pressure drop across the 5 um element rises as it loads up, so the bowl empties itself during normal operation without an operator or a timer. If your application runs lightly loaded for long periods, ask us about the manual-drain and automatic-drain variants of the same filter regulator.
