The AirTAC GFR600C25LJC3WT AirTAC Filter Regulator 1 in NPT 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 GFR600C25LJC3WT is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in one body. This size 600 unit has a 1 in NPT port, a 5 um filter element (code W), a differential-pressure drain and the low-pressure regulator type. A round gauge with a bar scale is fitted, the 600-size bowl is aluminium alloy, no mounting bracket is included, and maximum inlet pressure is 1.0 MPa (145 psi) with a working temperature of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, drain choices of differential-pressure, automatic or manual, and 40 um standard or 5 um optional filtration. Flow is published only as curves, so ask us to confirm the 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.

Feeds clean, regulated low-pressure air to clamping fixtures on a CNC machining cell, with the 5 um element helping protect the fixture cylinders and control valves from water and fine particulate carryover.
Sits at the drop of a cartoning or case-packing line to condition and regulate the air feeding bag-openers, pushers and hold-down cylinders, with the 1 in port matching a high-consumption main header.
Prepares and regulates supply air for large diaphragm or quarter-turn valve actuators on a water treatment or process skid, where the differential-pressure drain removes condensate without a manual drain routine.
Size and port set the flow path: this is the largest GFR size, 600, with a 1 in NPT port, so step down to 200, 300 or 400 if your circuit uses smaller ports. Drain is differential-pressure on this code; automatic (A) and manual (M) are the other decodable choices. Filtration is 5 um (code W); 40 um is the standard grade where finer filtration is not required. The regulator is the low-pressure type; its adjustment range is not published, so confirm it with us before ordering. The gauge scale here is bar, with MPa and psi scales available, and the embedded square gauge is the standard fitting. Thread is NPT on this code; PT is the standard and G is also an option, and J means no mounting bracket. Flow is published as curves rather than a single rating, so ask us to confirm sizing against your application.
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 G-series flow only as curves, not as a single rated figure, so we do not quote a number. Tell us your line pressure, downstream demand and acceptable pressure drop, and we will confirm the flow figures from the datasheet for this exact model before you order.
The W in the code selects the 5 um element; 40 um is the standard grade. Choose 5 um where downstream valves, cylinders or instruments need finer air, and 40 um for general plant air. Both grades are decodable options across the GFR family, so you can order the grade that matches your circuit.
