The AirTAC GFR400C10MLC2G 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 GFR400C10MLC2G is a GFR400-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is size 400 with a G3/8 (BSPP) port, a manual-drain polycarbonate bowl, a 40 um standard filter element, and the low-pressure regulator type for circuits whose set pressure sits below the standard regulator range (exact range on request). A round external gauge scaled in psi is fitted, and the mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um (code W) filtration, and gauge and thread options. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing and the datasheet for your application.

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.

Filtered, regulated air to gripper and actuator circuits on an assembly robot, with the round psi gauge giving operators a local set-point readout at the cell.
Holding a reduced clamping pressure on a machining fixture where the standard regulator range is more than the process requires and the low-pressure type fits.
Point-of-use conditioning ahead of cylinders on a packaging line, with the manual drain emptied as part of the scheduled stoppage routine.
Step between sizes 200, 300, 400 and 600 as the port and flow demand of the circuit changes; this unit is size 400 with a 3/8 port. Drain type is a real choice: this model is manual (periodic draining), while automatic and differential-pressure versions suit unattended installations. Filtration is 40 um standard; specify 5 um (code W) where downstream equipment needs finer air. The round external gauge fitted here is scaled in psi; the embedded square gauge and MPa or bar scales are alternatives. PT is the standard thread and G or NPT are catalogue options to order; the bracket is included. Flow for the GFR400 series is published as curves, not a single rating, so 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 the GFR400 series as curves, not as a single rated figure, so we do not quote a number here. Send us your flow and pressure requirements and we will confirm sizing against the datasheet on request.
The M in the code sets a manual drain, so the bowl is emptied periodically rather than automatically. The trailing G sets a G (BSPP) 3/8 port; PT is the standard thread and G or NPT are catalogue options you can order. The round external gauge fitted is scaled in psi, with square-gauge and other scale options available.
