The AirTAC GFR600C25LNWTK 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 GFR600C25LNWTK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation in a single body. This size 600 unit has a 1 in NPT port, a 5 um filter element (code W), a differential-pressure drain, and a low-pressure regulator, so it suits circuits that run at reduced setpoints rather than full line pressure. No gauge is fitted (code N), a reverse/check valve is built in, and the size 600 bowl is aluminium alloy. A mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um filtration, gauge options, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the figures for 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.

Point-of-use conditioning for clamps, tool-change actuators and purge air on a machining centre fed from a 1 in shop-air main, with the 5 um element protecting precision valves.
Conditioning a reduced-pressure circuit on a food or consumer-goods packaging line where gentle actuation runs well below standard regulator setpoints.
Filtered, regulated air for diverters, stop gates and pusher cylinders along a distribution-centre conveyor, with the check valve holding the set circuit against backflow.
Step up through sizes 200, 300, 400 and 600 as your port and air demand grow; this is the 600 frame with a 1 in NPT port, the largest in the range. Choose the drain to match maintenance: differential-pressure (as here) dumps condensate on a pressure drop, automatic drains unattended, and manual drains suit infrequently checked installations. Pick 40 um for general protection or 5 um (code W, as here) where downstream valves and cylinders need finer filtration. Gauges, thread style (PT standard, G and NPT to order) and the bracket are specified in the code. Because flow is published as curves and not 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 GFR600 as curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Send us your line pressure, set pressure and expected air demand, and we will confirm the sizing against the datasheet on request.
The N in the code means no gauge is fitted; gauge options can be specified on other GFR codes if you want a pressure readout. The L in the code marks the low-pressure regulator type, intended for circuits set below the standard range; its exact adjustment range is not published, so confirm it with us on request.
