The AirTAC GFR600C20LC3T 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 AirTAC GFR600C20LC3T is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has 3/4 in NPT ports, the low-pressure regulator type, standard 40 um filtration, a differential-pressure drain on the bowl, a round pressure gauge with bar scale fitted, and a mounting bracket included. The aluminium alloy bowl at this size is rated with the unit for a maximum inlet pressure of 1.0 MPa (145 psi) and a working temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and options include automatic or manual drains, a 5 um filter element (code W), square or round gauges with MPa, psi or bar scales, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet 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.

Feeding powder-coating guns and booth actuators from a plant air main, where the low-pressure regulator type holds a gentle working pressure and the 40 um element keeps powder equipment free of water and pipe scale.
Conditioning and regulating the air branch that serves loom jet controls and doffing cylinders, with the round bar gauge giving operators a local pressure readout at the machine.
Supplying the pusher and diverter cylinders on a bottling conveyor, where the 3/4 in NPT connection matches the main drop leg and the differential-pressure drain keeps condensate out of the valve bank.
Start with the size and port: size 600 with 3/4 in ports suits lines with higher air demand, while smaller sizes 200-400 cover lighter duties - match the port step to your supply piping and required flow. Choose the drain: differential-pressure (this unit) bleeds the bowl as pressure differential builds, automatic (code A) suits unattended installations, and manual (code M) needs periodic draining. Filtration is 40 um standard; specify 5 um (code W) if downstream valves or instruments need finer protection. This unit is the low-pressure regulator type and carries a round gauge with bar scale; square embedded gauges and MPa or psi scales are alternatives. Thread here is NPT; PT is the standard and G (BSPP) is an order option. Flow is published as curves, not a single rating, so 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 GFR600 as curves rather than a single rated figure, so no one flow number is quoted here. Tell us your line pressure and air demand and we will confirm the sizing from the datasheet before you order.
The L in the code marks the low-pressure regulator type, intended for circuits held at lower working pressures than the standard version; the exact adjustment range for this type is not published, so ask us to confirm it. Draining is differential-pressure: the bowl bleeds automatically as the pressure differential builds, with no manual draining routine required.
