The AirTAC GFR600C20LC2TK AirTAC Filter Regulator NPT3/4 Low-Pressure 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 GFR600C20LC2TK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size-600 unit carries a 3/4 in NPT port, a 40 um standard filter element, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure drop across the element rises. It is the low-pressure (L) regulator type, fitted with an external round gauge scaled in psi, a reverse/check valve that holds downstream pressure when the supply is lost, and a mounting bracket. The size-600 bowl is aluminium alloy, and the maximum inlet pressure is 1.0 MPa (145 psi) with an operating temperature range of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of PT, G or NPT thread, automatic, manual or differential-pressure drains, a 5 um (W) element option, gauge scale options, and a reverse-valve option. Flow for this series is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application on request.

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 clamp cylinders on a machining-cell pneumatic press, with the check valve holding the clamp circuit's pressure if the plant supply drops.
Installed at the drop of a carton-sealing and wrapping line, removing water and pipe scale from the shop air and holding a steady low-pressure setting for the actuator circuits.
Conditions the air supply to the pop-up gates and diverters on a distribution conveyor, with the differential-pressure drain clearing condensate through the shift without operator attention.
Start with the port step: size 600 in 3/4 in NPT is the largest GFR frame, so size up to it when your line's flow demand sits above what a 1/2 in unit can pass - and ask us to check the flow curve against your consumption before ordering. Choose the drain to match the site: differential-pressure (this unit) drains itself with flow, automatic (A) drains on a cycle, and manual (M) needs an operator. The 40 um element is the standard grade; specify the W code if you need 5 um. This unit is the low-pressure (L) regulator type - its exact adjustment range is not published, so confirm it with us. The round psi gauge is fitted here; the embedded square gauge is standard and MPa/psi/bar scales are available. PT is the standard thread and G or NPT are order options; the bracket is included on this 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 GFR-series flow as curves, not as a single rated number, so we do not quote a figure here. Send us your line pressure and air consumption and we will confirm the datasheet curve and sizing for this exact model on request.
The L in the code marks the low-pressure regulator variant, selected when the downstream circuit needs a lower setting than a standard GFR regulator delivers. Its exact adjustment range is not published in the material we hold, so please confirm the range with us before ordering. The rest of the decode is standard: 40 um filtration, differential-pressure drain, round psi gauge, check valve, and a 3/4 in NPT port.
