The AirTAC GFR400C10MF1WT AirTAC Filter Regulator NPT3/8 5um 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 GFR400C10MF1WT is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This 400-size unit is fitted with a 3/8 in NPT port, a 5 um filter element (the W grade, finer than the standard 40 um), a manual drain on the polycarbonate bowl, and an embedded square pressure gauge scaled in MPa. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). A mounting bracket is included; no reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and is available with manual, automatic or differential-pressure drains, 40 um or 5 um elements, square or round gauges (MPa, psi or bar scales), G, NPT or PT threads, and with or without a bracket. 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.

Feeding clean, regulated air to carton sealers, case packers and labelers on a packaging line, where the 5 um element protects directional valves and cylinders from water and debris.
Supplying regulated air to a CNC machining center for the tool changer, clamping fixtures and air-assist circuits, with the square MPa gauge giving a local set-point readout at the machine.
Regulating atomizing air at an automotive paint booth, where stable downstream pressure and 5 um filtration help keep spray finish quality consistent through a shift.
Choose the size by the port and flow step: sizes 200, 300, 400 and 600 map to progressively larger ports (here 3/8 in NPT) and higher flow capacity, so step up a size if your air demand may grow. Drain choice matters: this unit has a manual drain, which is emptied by hand as part of routine checks - choose automatic or differential-pressure drain if the unit will sit where it cannot easily be reached. The standard element is 40 um; this unit carries the finer 5 um W grade. Gauges can be square (embedded, as fitted here, MPa scale) or round (external), with MPa, psi or bar scales; threads come as PT (the standard), G (BSPP) or NPT; and a mounting bracket is included on this configuration.
Because AirTAC publishes flow only as curves and not as a single rated figure, we do not quote a flow number here - send us your application details 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 GFR series as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and the full datasheet figures on request before you order.
This unit is supplied with a manual drain: the bowl is drained by hand as part of routine maintenance. If the unit will be mounted where it cannot easily be reached, the same GFR family can be ordered with an automatic or differential-pressure drain instead.
