The AirTAC GFR400C10MLC1WT AirTAC Filter Regulator NPT3/8 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 GFR400C10MLC1WT is an AirTAC GFR400 filter regulator: water and particulate filtration plus pressure regulation in a single body. This configuration is built around a 3/8 in NPT port and a 5 um filter element (the fine W grade, against the 40 um standard), with a manual drain you open by hand to release collected condensate. The regulator is the low-pressure type, a round pressure gauge scaled in MPa is fitted, no reverse/check valve is included, a mounting bracket is supplied, and the bowl is metal. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GFR filter-regulator line, which spans sizes 200, 300, 400 and 600 with a range of port sizes, drain choices (differential-pressure, automatic or manual), 40 um or 5 um filtration, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow for the series is published as curves rather than a single rated figure, so ask us to confirm sizing and any datasheet figure for this model on request.

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.

Regulated air to the clamp cylinders on an assembly fixture that runs below standard regulator settings; the low-pressure type and the 5 um element keep the clamp valves fed with clean, steady air.
Point-of-use supply for paint spray guns on a finishing line: the 5 um element strips water and fine particles before the gun while the regulator holds the atomising pressure the booth recipe calls for.
A filter-regulator at the air drop to a CNC machining cell, conditioning the shop air that actuates tool-change cylinders and air chucks, with the manual drain emptied during scheduled maintenance.
Within GFR400 the real choices are the port size against the flow your line needs; the drain type (this unit is manual, so plan a routine drain check, or step to an automatic or differential-pressure variant); the filter grade (40 um standard versus the 5 um W element fitted here for finer protection); gauge style and scale (this one carries a round MPa gauge); and the thread family (NPT here, with PT and G available to order). A mounting bracket is included. Because AirTAC publishes flow as curves rather than one rated number, send us your application conditions 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 G-series flow as curves, not as a single rated figure, so there is no one number we can quote. Send us your line pressure and expected air demand and we will confirm sizing from the datasheet on request.
The M in the code sets a manual drain: condensate collects in the metal bowl and is released by opening the drain by hand, which suits installations checked on a routine. Automatic and differential-pressure drain variants exist in the same family if you would rather not rely on a manual check.
