The AirTAC GFR400C10MF2WT 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 GFR400C10MF2WT is an AirTAC GFR400 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This configuration is built for 3/8 in NPT ports, carries the 5 um filter element (the finer of the two published grades), a manual-drain polycarbonate bowl, an embedded square gauge reading in psi, and a mounting bracket. The regulator adjusts between 0.05 and 0.9 MPa (7-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C, non-freezing.
It is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet numbers 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.

Filter and regulate the air feeding spray guns and air-assisted applicators, so the 5 um element catches water and fine particulate before it reaches the finish while the regulator holds a steady gun pressure.
Supply clean, regulated air to the cylinders and ejectors that pick, place and seal cartons, with the fine element protecting close-tolerance valve spools along the line.
Feed bench-top pneumatic test rigs and fixture clamps from a shop-air drop, using the psi gauge for direct setpoint reading and the manual drain for a controlled daily bowl purge.
Every choice in this unit is decodable from the code. Step size first: 200, 300, 400 and 600 map to increasing port sizes and flow capacity, so match the size to the air demand of the circuit. Drain type matters: differential-pressure (the default) drains only while air is flowing, automatic drains continuously, and manual - as on this unit - drains when you open it, which suits installations checked on a routine. Filter grade is 40 um standard or 5 um (code W) for finer protection downstream; this unit carries the 5 um element. Gauges are embedded square as standard with MPa, psi or bar scales, threads come as PT (the standard), G or NPT, and a bracket is included unless coded J. Because flow is published as curves rather than a single rating, 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 this series as curves rather than a single rated figure, so we do not quote one number. Send us your line pressure and air consumption and we will confirm the datasheet flow curve and sizing for your application on request.
Manual drain means the bowl is emptied by opening the drain when you choose, which suits installations checked as part of a routine. If you cannot rely on regular checks, the automatic or differential-pressure drain options in the same series drain the bowl without operator action. This unit also carries the 5 um (code W) element instead of the 40 um standard.
