The AirTAC GFR400C10AJC1WT AirTAC Filter Regulator NPT 3/8 in 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 GFR400C10AJC1WT is an AirTAC GFR400 filter regulator: a 5 um filter element and a pressure regulator combined in one body, sized for a 3/8 in NPT port. It strips water and particulate from compressed air, then holds downstream pressure steady across the standard adjustment range of 0.15-0.9 MPa (20-130 psi). This configuration has an automatic drain that expels collected condensate from the polycarbonate bowl without manual attention, a round gauge on an MPa scale for setting pressure, and is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and can be ordered with manual, automatic or differential-pressure drains, a 40 um standard or 5 um (W) element, embedded square or external round gauges in MPa, psi or bar scales, PT, G or NPT threads, and with or without a bracket. Flow for this unit is published as a curve rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeding clean, pressure-stabilized air to solenoid valves, grippers and tool-clamp cylinders on a CNC machining center, with the 5 um element guarding fine pilot valves and the automatic drain keeping the bowl clear through unattended shifts.
Regulating air to pick-and-place cylinders and stopper gates along a bottling conveyor, where steady downstream pressure keeps cycle timing repeatable and the round MPa gauge gives operators a visible setpoint.
Supplying regulated air to pneumatic nutrunners and clamping fixtures at an automotive assembly cell; the filter stage removes water and scale before it reaches the tools, and the automatic drain suits a cell that runs without an attendant.
Size and port set the air capacity: this is the 400 frame with a 3/8 in NPT thread, and you can step up or down through the 200-600 range as your demand changes. Choose the drain to suit the installation - automatic (this unit) for unattended duty, manual where the bowl is checked routinely, or the differential-pressure default. Pick the element grade: 40 um standard or 5 um (W, as here) for finer protection of valves and cylinders. Gauges come embedded square or external round, in MPa, psi or bar scales; threads are PT (standard), G (BSPP) or NPT; and a mounting bracket is optional - this code (J) omits it. Because flow is published as curves rather than a single rating, send us your application details 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 G-series flow as performance curves, not a single rated figure, so we do not quote a number here. Tell us your application and operating pressure and we will confirm the flow curve and correct sizing from the datasheet on request.
The W in the code selects the finer 5 um element instead of the 40 um standard, and the A selects an automatic drain that expels condensate on its own. If you would rather empty the bowl manually or use the differential-pressure default, the same GFR400 frame can be ordered that way.
