The AirTAC GFR600C20ALNTK 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 GFR600C20ALNTK is a size 600 filter regulator: water and particulate filtration plus pressure regulation combined in one body. This configuration is built with a 3/4 in NPT port, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, and a low-pressure regulator type. No gauge is fitted on this variant, and a reverse/check valve is included. At size 600 the bowl is aluminium alloy, and a mounting bracket is supplied.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, drain choices (differential-pressure, automatic or manual), a 40 um standard or 5 um (W) element, gauge and thread options. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

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 filtered, low-pressure regulated air to clamping and hold-down cylinders on a factory press line, with the automatic drain keeping condensate out of the valves between shifts.
Supplying diverters, stoppers and pusher cylinders on a packaging conveyor, where the 3/4 in port serves a main branch line and the 40 um element protects downstream actuators.
Conditioning supply air on a paint spray or coating line, using the low-pressure regulator to hold a gentle, stable setpoint while the automatic drain handles moisture carryover.
Size and port are the first choice: step up through 200/300/400/600 as your required flow and pipe size grow - this unit is already the size 600, 3/4 in step. Drain type is a real decision: automatic drain (fitted here) suits unattended duty, while manual and differential-pressure drains are available in the family. Filter grade is 40 um standard, with 5 um (code W) where finer filtration is needed. Gauge and scale (round or square, MPa/psi/bar) can be ordered if you want a visual setpoint reference - this variant ships without one. Thread is NPT here; PT is the standard thread and G (BSPP) is also a catalogue option. Bracket is included.
Because flow is published as curves and not as a single rating, 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 GFR series as curves rather than a single rated figure, so we do not quote one number. Tell us your application and we will confirm the flow and datasheet figures for this exact model on request before you order.
The N in the code means no gauge is fitted on this unit, so you set and verify the regulator with your own instrument at the port. If you prefer a built-in reference, the GFR family can be ordered with an embedded square gauge or an external round gauge in MPa, psi or bar scale.
