The AirTAC GFR600C20LNT 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 GFR600C20LNT is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This size 600 unit carries a 3/4 in NPT thread, the standard 40 um filter element and a differential-pressure drain that discharges collected condensate as the pressure drop across the element calls for it. It is the low-pressure (L) regulator type, fitted with a mounting bracket and supplied without a gauge; the metal bowl at size 600 is aluminium alloy. Rated inlet pressure is 1.0 MPa (145 psi) and working temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, PT as the standard thread and G (BSPP) or NPT as catalogue options, plus choices of drain type, 40 um or 5 um filtration, gauge style and scale, and low-pressure regulation. Flow for the series is published as curves rather than a single rating, so ask us to confirm sizing 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.

Filtered, low-pressure regulated air to spray guns on a finishing line, where the 40 um element keeps moisture and particles out of the finish and the low-pressure regulator suits gun and atomising set pressures.
Air supply to the sealing jaws and sorting cylinders on a packaging conveyor, with the differential-pressure drain clearing condensate through long shifts and the 3/4 in port feeding a high-consumption zone.
Low-pressure regulated air to actuators and fixtures on a workshop test rig, where the low-pressure (L) regulator type matches reduced set pressures and the mounting bracket secures the unit to the bench frame.
Size GFR by the port and flow your line needs: this unit is size 600 with a 3/4 in NPT thread, the largest step in the family, so step down to 200, 300 or 400 if your port and flow are smaller. This configuration uses the standard 40 um element (code W gives 5 um where downstream equipment needs finer filtration) and a differential-pressure drain; automatic (A) and manual (M) drains are the alternatives. It is the low-pressure (L) regulator type, and the exact regulation band for that type is not published in the material we hold, so confirm it against your set pressure with us before ordering.
No gauge is fitted here (code N); gauges with MPa, psi or bar scales are catalogue options. The thread on this unit is NPT; PT is the AirTAC standard and G (BSPP) is also available. Flow is published as curves, not a single rated figure, so send us your flow and pressure requirements and we will confirm sizing from 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 rather than a single rated figure, so we do not quote a number here. Tell us your required flow and working pressure and we will confirm sizing from the datasheet on request.
The model code specifies the unit without a gauge. Gauges with MPa, psi or bar scales are catalogue options you can order with the unit. The other key choices in this configuration are the low-pressure (L) regulator type, the 40 um standard filter element, the differential-pressure drain and the 3/4 in NPT thread.
