The AirTAC GFR600C20LF3TK AirTAC Filter Regulator NPT3/4 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 GFR600C20LF3TK 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 built with a 3/4 in NPT port, the standard 40 um filter element, a differential-pressure drain on the bowl, a low-pressure regulator type, an embedded square gauge scaled in bar, and a reverse (check) valve fitted. The size-600 bowl is aluminium alloy, and a mounting bracket is included.
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, drain choices (differential-pressure, automatic or manual), an optional 5 um element, gauge and thread options, and a low-pressure regulator variant. Flow is published as curves rather than a single rating, so ask us to confirm sizing and any datasheet figure against 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.

Feed a workshop pneumatic press from a 3/4 in main: the element strips water and swarf from the supply while the regulator holds a steady reduced pressure to the press cylinder and its valve stack.
Serve the air cylinders and grippers on a packaging conveyor line, where the check valve keeps the circuit pressurised during brief supply dips and the drain carries condensed water out of the bowl.
Install at the take-off point of a factory air header to condition and regulate the branch feeding multiple downstream tools, with the bar-scaled square gauge giving operators a local setpoint reference.
Start with the port step: this unit is 3/4 in NPT, so match it to the line size your air consumption requires and step up or down a size if your flow demand changes. The drain here is differential-pressure, which bleeds the bowl automatically as the pressure differential builds - choose automatic or manual only if your duty cycle or maintenance routine calls for it. Filtration is the standard 40 um grade; specify the 5 um (W) element if downstream equipment needs finer air. The gauge is the embedded square type scaled in bar, with an external round gauge and MPa/psi scales available as options; the check valve (K) holds downstream pressure if the supply drops.
Flow for this family is published as curves, not a single rated figure, so send us your application details and we will confirm sizing from the datasheet before you order. Thread is NPT here; PT is the standard and G (BSPP) is also a catalogue option.
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 rather than a single rated figure, so there is no one number we can honestly quote. Tell us your line pressure and air demand and we will confirm the sizing from the datasheet on request before you order.
K means a reverse (check) valve is fitted, so downstream pressure is held if the upstream supply falls. The L in this code marks the low-pressure regulator type; its exact adjustment range is not published in the material we hold, so ask us to confirm it from the datasheet for your setpoint.
