The AirTAC GFR600C25LC1TK AirTAC Filter Regulator NPT 1 in 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 GFR600 series combines water and particulate filtration with pressure regulation in a single body. This GFR600C25LC1TK is the size 600 unit with a 1 in NPT port, a 40 um filter element and a differential-pressure drain, the default drain type for the series. Size 600 units use an aluminium alloy bowl. It is the low-pressure type, fitted with an external round gauge reading in MPa and a built-in reverse-flow check valve, and a mounting bracket is included. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, PT as the standard thread and G or NPT as order options, 40 um standard or 5 um (code W) filtration, differential-pressure, automatic or manual drains, and square or round gauges with MPa, psi or bar scales. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures 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.

On a main 1 in header feeding large air cylinders and clamps in a plant such as a corrugated-box folder-gluer line, this unit filters condensed water and particulate out of the supply and holds the regulated pressure the actuators were set up for, with the check valve holding the downstream setting if upstream supply dips.
Diaphragm-actuated valves on water-treatment or chemical skids need a clean, steady, modest supply pressure to their positioners and pilot circuits. This low-pressure type filter regulator on the actuation branch filters the plant air and sets that supply pressure, with the MPa gauge giving a local reading at the valve.
A bottling or cartoning line's 1 in air header runs labelers, case packers and sealers that are sensitive to dirty or wandering air pressure. This unit mounted at the header take-off removes water and debris and regulates the branch, while the differential-pressure drain clears accumulated condensate in service.
The real choices in this series are the size and port step (200/300/400/600, ports 1/8 to 1 in) matched to your line's flow demand, the drain type (differential-pressure as here, automatic, or manual), the filter grade (40 um standard, 5 um with code W), the gauge (embedded square as standard, external round as here, with MPa, psi or bar scales), the thread (PT standard; G and NPT to order) and whether a bracket is included. This unit is the low-pressure type; its adjustment range is not published in the catalogue, so confirm your set pressure with us before ordering. Because flow is published as curves rather than a single rated figure, send us your application details and we will confirm sizing against 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, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, set pressure and the flow your application needs, and we will confirm from the datasheet whether this size 600, 1 in port unit is correctly sized before you order.
L is the low-pressure type of regulator, intended where the set pressure sits below the standard type's range; the exact adjustment range for the low-pressure type is not published in the catalogue, so confirm your set pressure with us and we will verify it from the datasheet. The rest of the code decodes as: size 600 with a 1 in NPT port (PT is the series standard; G and NPT are order options), 40 um filter element, differential-pressure drain, round gauge with MPa scale, reverse-flow check valve fitted, and mounting bracket included.
