The AirTAC GFR400C10C2WGK AirTAC Filter Regulator G3/8, 5 um 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 GFR400C10C2WGK is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built around a G3/8 (BSPP) port, the finer 5 um filter element, a differential-pressure drain, and a standard regulator with an adjustment range of 0.15-0.9 MPa (20-130 psi). It is fitted with an external round gauge scaled in psi, a reverse/check valve, and a mounting bracket; the bowl for the 400 size is polycarbonate.
This is a genuine AirTAC part. The GFR family covers sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, plus options for drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um), gauge style and scale (MPa, psi or bar), reverse/check valve, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Filtered, regulated air to pneumatic clamps and tool-change cylinders on a CNC machining centre, with the 5 um element protecting fine-tolerance directional valves and the check valve holding downstream pressure through upstream dips.
A stable regulated supply to diverter gates and stoppers on a parcel-sorting conveyor line, where the 3/8 port matches the drop-leg piping and the psi-scaled round gauge lets maintenance staff set line pressure at a glance.
Clean, regulated air to actuated valves and small cylinders on a laboratory test rig, where the 5 um filtration keeps contaminants out of precision instruments and the regulator holds a repeatable setpoint between runs.
Size and port are the first choices: GFR200, 300, 400 and 600 step up in port and flow capacity, so match the G3/8 port here to your line size and air demand. Drain type matters: this unit uses the differential-pressure default, with automatic and manual drains as the alternatives. Filter grade: 40 um is the standard element, while the 5 um element fitted here (code W) suits finer-particle protection. Gauge: the embedded square gauge is standard, and this unit adds an external round gauge scaled in psi (MPa and bar scales are the other options). Thread: PT is the standard, with G and NPT as order options; the mounting 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 PC bowl must not be cleaned with solvents — wipe it with a dry cloth. 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 GFR400 as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow curve and the datasheet figures on request.
C indicates the external round gauge option and 2 sets its scale to psi; W is the 5 um filter element instead of the 40 um standard. The code also carries G for the G (BSPP) thread and K for the fitted reverse/check valve, while the drain is the differential-pressure default.
