The AirTAC GFR600C25LJC3WTK AirTAC Filter Regulator NPT1 5um 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 GFR600C25LJC3WTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit is built around a 1 in NPT port and carries the W-coded 5 um filter element, a differential-pressure drain, the low-pressure regulator type, a round pressure gauge reading in bar, and a reverse/check valve (code K). The bowl on size 600 units is aluminium alloy, and this configuration is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in up to 1 in, and options including manual or automatic drains, the 40 um standard element, square or round gauges with MPa, psi or bar scales, G or NPT threads in place of the PT standard, and an optional mounting bracket. Flow for the series is published as curves rather than a single rating, so ask us to confirm the figures against the datasheet 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.

Feeding filtered, pressure-controlled air to clamping fixtures and pneumatic vises on a CNC machining cell, where the 5 um element helps protect the clamping valves and the low-pressure type suits gentler workholding circuits.
Conditioning the air feeding cylinders, diverters and stop gates along a packaging conveyor line, with a 1 in take-off from the main and the fitted check valve helping prevent backflow into the supply leg.
Supplying clean, regulated air to spray guns in a finishing booth, where water and particulate removal ahead of the gun and a controlled low-pressure setting are part of the daily setup.
Size 600 is the largest step in the GFR range, and this unit takes a 1 in port - match the size and port to the flow your line needs, stepping up from 200/300/400 when demand outgrows the smaller bodies. Drain choice is real: this unit uses the differential-pressure drain (the default); automatic (A) and manual (M) drains are orderable on the family. Filter grade is a decodable choice: 40 um is standard, and the W in this code selects the finer 5 um element for protecting sensitive downstream equipment. Gauge scale is selectable (MPa, psi or bar) - this unit carries a round gauge reading in bar. Thread: PT is the standard for the series, with G and NPT as orderable options (this unit is NPT). Bracket is optional; this configuration ships without one. Note this is the low-pressure regulator type; its exact adjustment range is not published in the sheet we work from. Because flow is published as curves rather than a single rating, ask us to confirm sizing against the datasheet 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 this series as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure and downstream demand and we will confirm the sizing against the datasheet on request.
The W in the code selects the 5 um element instead of the series-standard 40 um, which suits circuits protecting sensitive valves and instruments. The L in the code also makes this the low-pressure regulator type; its exact adjustment range is not published in the sheet we work from, so confirm it with us before ordering if your set pressure is critical.
