The AirTAC GFR400C10MC2G AirTAC Filter Regulator G3/8 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 GFR400C10MC2G is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in one body. This configuration has a G3/8 (BSPP) port, a 40 um standard filter element, a manual drain on a polycarbonate bowl, a round pressure gauge reading in psi, an included mounting bracket, and no reverse-flow valve. With manual drainage, an operator opens the drain at the bottom of the bowl to expel collected moisture.
This is a genuine AirTAC part from the GFR400 series. The GFR line is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, drain choices (differential-pressure, automatic or manual), 40 um or 5 um (W) filtration, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating; we confirm datasheet figures 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.

| (blank) | Pressure gauge fitted (blank). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

Filtered, regulated air for pneumatic clamps and tool-change actuators on a machining center, with the psi gauge giving operators a visible setpoint at the machine.
Clean, steady air to carton sealers and case erectors, where the 40 um element keeps debris out of directional valves and cylinders.
Supply for spray guns and air-assisted applicators, where water and particle removal plus a stable setpoint protect finish quality.
Size and port set the capacity: this unit is size 400 with a G3/8 port, and the GFR range steps through sizes 200/300/400/600 and ports 1/8 to 1 inch. Drain options are differential-pressure (default), automatic (A) or manual (M - this unit); with manual drainage the regulation range is 0.05-0.9 MPa (7-130 psi). Filter grade is 40 um standard or 5 um with code W. An embedded square gauge is standard, with an optional external round gauge in MPa, psi or bar scales - this unit carries a round psi gauge. Thread here is G (BSPP); PT is the standard thread and G or NPT are order options. A mounting bracket is included. 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 G-series flow as curves rather than a single rated figure, so we do not quote one number here. Send us your line pressure and air demand and we will confirm the flow and datasheet figures for this exact model on request.
This unit carries code M - a manual drain that an operator opens to expel collected water from the polycarbonate bowl. The same size is available with automatic (A) or differential-pressure drainage; tell us which you prefer when ordering.
