The AirTAC GFR400C10F2GK AirTAC Filter Regulator G3/8, 40 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 GFR400C10F2GK is an AirTAC GFR400 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air at the 40 um standard grade, then regulates downstream pressure with the standard-type regulator over 0.15-0.9 MPa (20-130 psi). This configuration has G3/8 ports, a differential-pressure drain that bleeds condensate automatically as flow passes through, an embedded square gauge reading in psi, a reverse/check valve fitted, and a mounting bracket included. Maximum inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C, non-freezing. The bowl on this size 400 unit is polycarbonate (PC).
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, optional 5 um filtration (code W), manual or automatic drain variants, gauge scale choices, and G or NPT thread options alongside the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application before ordering.

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.

Feeding clean, regulated air to carton-forming and sealing heads on a packaging line, where the differential-pressure drain keeps condensate off the valves during continuous running.
Supplying regulated air to conveyor stop-gate and diverter cylinders, with the psi square gauge letting line staff verify set pressure at a glance.
Mounted on a machine tool's pneumatic panel with the included bracket, filtering shop air to 40 um and holding a stable setting for clamping and tool-change circuits.
Size 400 with 3/8 in ports suits lines where the required flow sits above the 300 frame; step up to 600 or down to 300 depending on the flow curve for your consumption. The differential-pressure drain on this unit handles condensate automatically during flow; choose manual drain (M) for low-flow or intermittently used lines, or automatic drain (A) where the line stops often. The 40 um grade is the standard element; specify W for 5 um where finer particulate protection is needed. The fitted square gauge reads psi; MPa and bar scales and an external round gauge are alternatives. Thread here is G (BSPP); PT is the catalogue standard and NPT is orderable. A bracket is included. Flow 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 as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and air consumption and we will confirm the flow from the datasheet for your application on request.
The differential-pressure drain on this configuration bleeds condensate automatically while air is flowing, with no operator action. If your line runs intermittently or at very low flow, a manual-drain (M) or automatic-drain (A) variant of the same GFR400 size may suit better - ask us for those codes.
