The AirTAC GFR400C10JF1WTK AirTAC Filter Regulator NPT3/8 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 GFR400C10JF1WTK is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in one body. This configuration is built with a 3/8 in NPT port, the finer 5 um filter element (code W, against the 40 um standard), a differential-pressure drain, an embedded square gauge scaled in MPa, and a reverse/check valve fitted. No mounting bracket is included, so plan your fixing method accordingly.
It is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and choices of drain type, filter grade, gauge and scale, thread (PT standard, G and NPT orderable) and bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, 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.

Filtered, regulated air feeding the pneumatic clamps and tool-changer cylinder on a machining centre, with the reverse/check valve helping hold the circuit if upstream supply dips.
Conditioning air for carton-sealing and case-erector cylinders on a packaging conveyor, where the 5 um element protects the directional valves and the regulator sets a stable working pressure.
A filter regulator at each workstation drop on an assembly line, feeding air tools and small pneumatic cylinders with water and particulate stripped out before use.
Size and port are the first decision: GFR400 with a 3/8 in NPT port sits mid-range in the GFR line, which steps from 1/8 in to 1 in as size rises from 200 to 600 - match that step to the flow your circuit needs. This unit carries the 5 um W element instead of the 40 um standard, a differential-pressure drain, a square gauge scaled in MPa (psi and bar scales are orderable), and a reverse/check valve. With this drain type the regulation range is 0.15-0.9 MPa (20-130 psi); a manual-drain variant would open 0.05-0.9 MPa (7-130 psi). Thread here is NPT, with PT as the standard and G also orderable, and no bracket is fitted. Because flow is published as curves, not a single rating, send us your flow and pressure requirements and we will confirm sizing against the datasheet before you order.
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 there is no one l/min or SCFM number we can honestly quote. Tell us your working pressure and required flow and we will confirm the sizing from the datasheet on request.
The W in the code GFR400C10JF1WTK selects the 5 um element; the GFR400 standard grade is 40 um. Choose 5 um where downstream valves and cylinders are more sensitive to particulate, and 40 um for general duty - both are catalogue options in this size.
