The AirTAC GFR600C25LC2WTK AirTAC Filter Regulator NPT1 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 GFR600C25LC2WTK is a 600-size filter regulator: it removes water and particulate from compressed air and holds downstream pressure at a set point in one body. This configuration is built for a 1 in NPT port, carries the fine 5 um filter element (code W), drains condensate by differential pressure, and is the low-pressure type (code L) for circuits that run at reduced supply pressure. It is fitted with an external round gauge scaled in psi (code C2) and a reverse/check valve (code K), and the mounting bracket is included. At size 600 the bowl is aluminium alloy, and the maximum inlet pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the G-series filter regulator line, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and PT, G or NPT threads. Drain types, filter grades, gauge styles and scales, low-pressure variants and check valves are all orderable options. Flow is published as curves rather than a single rated figure, so we confirm flow and other datasheet values for your application on request.

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 stamping or assembly press fed from a plant ring main, this unit filters the incoming air to 5 um and holds a reduced, stable pressure to the press cylinders, with the check valve protecting the set point if supply dips.
At the drop of a cartoning or wrapping line, the 1 in NPT port serves the high-demand main, the fine element protects directional valves and actuators, and the psi gauge lets maintenance verify settings at a glance.
On a process line running actuators or clamps at reduced supply pressure, the low-pressure type regulator sets the working pressure, the aluminium bowl with differential-pressure drain handles condensate automatically, and the bracket secures the unit to the frame.
Size 600 with a 1 in NPT port is the correct step when the air demand at the machine is at the top of the G-series port range; smaller sizes (200/300/400) step down through 1/8 in to 3/4 in. Choose the 5 um element (W) where downstream valves, cylinders or instruments need finer filtration than the 40 um standard, and keep the differential-pressure drain (the default here) where supply pressure fluctuates enough to purge the bowl automatically. The low-pressure type (L) suits circuits that operate well below standard supply pressure; its exact adjustment range is not published in the catalogue, so ask us to confirm it. The round psi gauge (C2) gives a familiar US readout, and the check valve (K) holds downstream settings if upstream pressure is lost. PT is the standard thread; G (BSPP) and NPT are orderable options, and a bracket is included. Because flow is published as curves rather than 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 GFR600 as curves, not as a single rated figure, so there is no one number we can honestly quote. Send us your application details and we will confirm the flow from the datasheet curves for your inlet pressure and set point before you order.
The W in the code selects the 5 um filter element instead of the 40 um standard, giving finer protection for downstream valves and instruments. The K selects a reverse/check valve, which holds the downstream pressure setting if upstream supply is lost. Both are orderable options on the GFR range, as are drain type, gauge style and scale, and the low-pressure regulator variant fitted here.
