The AirTAC GFR600-20LC2T 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 PT3/4" 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 GFR600-20LC2T 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 the low-pressure type, fitted with an external round gauge scaled in psi, a 40 um standard filter element, and a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the bowl is sufficient. The 3/4 in NPT port suits a main air line feeding a work cell or machine header. The size-600 bowl is aluminium alloy, and the unit is rated to 1.0 MPa (145 psi) maximum inlet pressure with an operating temperature 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 to 1 inch, a choice of drain type, 40 um or 5 um filtration, gauge style and scale, PT, G or NPT thread, and bracket options. Because flow is published as curves rather than a single rated figure, we confirm the datasheet and flow 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

Installed at the drop from a 3/4 in plant air main to a machine's header, it strips water and scale from the incoming air and holds the machine's working pressure steady through shift-long cycling.
Feeding a fixture-clamping circuit on a machining cell, the low-pressure regulator holds the clamping pressure the fixture was designed for while the 40 um element keeps debris out of the clamping valves.
On a packaging or conveyor line using air jets and small actuators, it cleans the supply and keeps the blow-off and actuation pressure consistent so product handling stays repeatable.
Start with the port and size step: this unit is size 600 with a 3/4 in NPT port, the largest step in the range, chosen when the line's required flow demands the bigger passage. Choose the drain to match the installation: differential-pressure (as here) needs no operator attention, automatic drains continuously, and manual drain suits supervised points. Filter grade is 40 um standard; specify the W option for 5 um where finer protection is needed. This unit is the low-pressure type, so if your circuit runs at reduced working pressures, confirm suitability with us before ordering. Gauge options are the embedded square gauge or an external round gauge, scaled in MPa, psi or bar (this unit: round, psi). Thread is NPT here; PT is the standard and G (BSPP) is also an order option. A mounting bracket is included.
Flow for this family is published as curves, not a single rated number, so ask us to confirm sizing against your application and the datasheet 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 family as curves, not as a single rated figure, so we do not quote a rated flow number. Tell us your line pressure and the flow your application needs and we will confirm the sizing from the datasheet on request before you order.
The L in the code marks the low-pressure regulator type, intended for circuits working at reduced pressures rather than full line pressure; its exact adjustment range is not published, so we confirm it on request. C2 marks an external round gauge scaled in psi. The unit also carries the standard 40 um element and a differential-pressure drain.
