The AirTAC GFR400C10MLJC1WT AirTAC Filter Regulator 3/8 in NPT 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 GFR400C10MLJC1WT is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is built with a 3/8 in NPT port, a fine 5 um filter element, a manual drain on the bowl, and the low-pressure regulator type, so it suits circuits that must be set well below standard regulator ranges. The fitted round gauge reads in MPa, the bowl on this size is polycarbonate (PC), no mounting bracket is included, and 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 in to 1 in, and is offered with manual, automatic or differential-pressure drains, 40 um standard or 5 um fine filtration, square or round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application 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.

Filters the shop air feeding hot-glue applicator cylinders and holds the reduced pressure the glue heads were set up for, with the 5 um element protecting the small metering valves from particulate.
Conditions and regulates the air supplied to test fixtures that must run at low set pressures, with the MPa gauge giving the operator a direct reading at the bench.
Feeds filtered, regulated air to the stopper and pusher cylinders along a packaging conveyor, with the manual drain emptied during scheduled line cleaning.
Start with the port step: this unit is the size 400 body with a 3/8 in NPT port, one step up from 1/4 in, so size up if your circuit sits near the top of a smaller unit's flow curve. This code carries the 5 um element (the 40 um standard element is the blank option) and a manual drain, which means someone drains the bowl on a routine; choose the automatic or differential-pressure drain code if no one will be at the machine. The low-pressure type regulator is the right pick when setpoints sit below a standard regulator's comfortable range; the exact adjustment range for this low-pressure variant is not published, so confirm it with us. The round MPa gauge is fitted; square gauges and psi or bar scales are order options. PT is the standard thread and G or NPT are order options, and a bracket can be added where this no-bracket code omits it.
Because AirTAC publishes flow as curves and not a single rated figure, 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 this family as curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Send us your required flow and working pressure and we will confirm the sizing against the datasheet on request before you order.
The M in the code specifies a manual drain: the bowl is emptied by hand as part of routine maintenance. The GFR family is also available with an automatic drain (code A) or the differential-pressure drain (blank), which suit installations where nobody is regularly at the machine. This unit also carries the 5 um element (code W) instead of the 40 um standard element, and the low-pressure regulator type.
