The AirTAC GFR600C20LC3WT 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 GFR600C20LC3WT is an AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation combined in a single size-600 body with 3/4 in NPT ports. This configuration carries the W element (5 um filtration instead of the standard 40 um), the low-pressure regulator type, a differential-pressure drain that bleeds the bowl automatically as the pressure drop across the element builds, and a round external gauge scaled in bar. The size-600 bowl is aluminium alloy, and the unit is supplied with a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, in PT (standard), G and NPT threads, with a choice of drain type, filter grade, gauge style and scale, and standard or low-pressure regulation. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeds filtered, regulated low-pressure air to clamping fixtures on a CNC machining cell, where the 5 um element protects the clamp cylinders and the bar-scaled gauge lets the setter read the clamping circuit directly.
Installed at the drop of a packaging conveyor's air main, it removes water and fine particles before air reaches the diverters and seal bars, and holds the supply steady for the low-pressure actuators that handle the product.
Supplies regulated air to low-pressure air bearings, tension rollers and cleaning jets on a textile or paper converting machine, with the differential-pressure drain keeping the aluminium bowl clear of accumulated condensate during long runs.
Size 600 with 3/4 in ports sits at the top of the GFR range, so step up or down (200/300/400/600) against the air demand of the line rather than the pipe size alone - and because flow is published as curves, not a single rating, ask us to confirm sizing against your application before ordering. This unit is the low-pressure regulator type and its exact adjustment range is not published in the catalogue sheet; confirm the set pressure with us. Filtration is 5 um (code W) - choose 5 um where downstream valves and cylinders need finer protection, or the standard 40 um where coarse water and particle removal is enough. The differential-pressure drain needs no daily attention but relies on a sufficient pressure differential; if your circuit runs at low or fluctuating pressure, ask about the automatic or manual drain variants. The gauge fitted here is the external round type scaled in bar; embedded square gauges and MPa or psi scales are the other catalogue options. NPT is the thread on this code; PT (standard) and G are the other order options. A mounting bracket is included.
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 flow as curves, not as a single rated figure, so we will not quote you a number that is not in the datasheet. Size 600 with 3/4 in ports is the largest step in the GFR range, and we will confirm the curve and check it against your actual air demand before you order - just send us your flow requirement and line pressure.
The L in the code selects the low-pressure regulator variant, intended for circuits that run below the standard regulator's range. The exact adjustment range for the low-pressure type is not published on our sheet, so confirm your set pressure with us and we will verify it from the datasheet. Maximum inlet pressure remains 1.0 MPa (145 psi), and the unit operates from -5 to 70 C (non-freezing).
