The AirTAC GFR400C10JF2WTK 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 AirTAC GFR400C10JF2WTK is a GFR400 filter regulator: it removes water and particulate from compressed air and holds downstream pressure in one body. This configuration has a 3/8 in NPT port, a differential-pressure drain, a 5 um filter element (the finer of the two catalogue grades), an embedded square gauge reading in psi, and a reverse/check valve fitted. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing. The 400 size uses a polycarbonate bowl, and no mounting bracket is included (code J).
This is a genuine AirTAC part. The GFR family is made in 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in, and options for drain type, 40 um or 5 um filtration, gauge style and scale, G or NPT threads, brackets and a reverse valve. Flow for the series is published as curves rather than a single rating, so ask us to confirm sizing and datasheet 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.

Feeding the pneumatic valves and clamps on a CNC machining centre: the 5 um element protects directional valves from particles and water while the regulator holds a steady set pressure for consistent clamping.
Supplying cylinders and grippers on a packaging or bottling line, where the fitted check valve holds the downstream circuit against momentary supply dips and the psi gauge lets operators verify set pressure at a glance.
Point-of-use preparation at an assembly or robotics cell: filtered, regulated air for air tools and pick-and-place actuators, with the differential-pressure drain carrying collected condensate away during operation.
Size and port set the air capacity: the GFR400 steps up from the 200 and 300 bodies and takes a 3/8 in port here, so match the size to the flow your line needs rather than to the pipe alone. The remaining choices are all decodable: differential-pressure drain (fitted here) versus automatic or manual; 5 um filtration (code W) versus the 40 um standard; the embedded square gauge in psi, with MPa and bar scales also available; PT as the standard thread with G and NPT as order options; and bracket or no bracket. Because flow is published as curves rather than a single rated figure, 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 rather than a single rated figure, so there is no one number we can quote. Tell us your working pressure and air consumption and we will confirm the flow from the datasheet on request before you order.
The W code fits the finer 5 um element, the right choice upstream of precision valves, probes and instruments; the 40 um standard grade suits general cylinders and tools. This unit also carries a reverse/check valve (code K), a square psi gauge, a differential-pressure drain, and no mounting bracket (code J).
