The AirTAC GFR600C20ALJNT 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 GFR600C20ALJNT is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a 3/4 in NPT port, a 40 um standard filter element, an automatic drain that expels collected condensate without manual attention, and the low-pressure regulator type. It is supplied without a pressure gauge, without a mounting bracket, and without a reverse/check valve. As a size-600 unit, its drain bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, a choice of 40 um or 5 um (W) filtration, and differential-pressure, automatic or manual drains. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Filtered, low-pressure regulated air feeding the flap-fold and taping cylinders on a carton sealer, with the automatic drain clearing condensate between shifts.
Conditioning shop air for spray guns in a finishing booth, where the 40 um element protects the finish from water and particulate and the low-pressure regulator type suits low-pressure gun setups.
Supplying filtered, regulated air to clamp and purge circuits on robotic weld fixtures, with the 3/4 in port serving the cell's main drop.
Step up through the GFR sizes (200, 300, 400, 600) as your port and air demand grow; this unit sits at the top of the range with a 3/4 in NPT port. Choose the drain to match the installation: automatic (as fitted here) suits unattended duty, manual suits periodic service, and differential-pressure is the catalogue default. Filter grade is 40 um standard, with 5 um (code W) available where finer filtration is needed. Gauge, scale, thread (PT standard, G or NPT to order) and bracket are all decodable choices - this unit has no gauge and no bracket. Because flow is published as curves and not as a single rating, ask us to confirm sizing against your application before ordering; the exact regulation range of the low-pressure type is likewise confirmed on request.
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. Tell us your application and we will confirm the flow curves and datasheet figures on request before you order.
No. The N in the code means no gauge is fitted. Gauges are an order option on GFR units, in embedded square or external round form with MPa, psi or bar scales - ask us to quote a gauge-equipped variant if you need one.
