The AirTAC GFR400C10JC2W AirTAC Filter Regulator PT3/8, 5 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 GFR400C10JC2W is an AirTAC GFR400 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This configuration is sized for 3/8 in PT ports, carries a 5 um filter element (code W), drains condensate by differential pressure, and is fitted with an external round gauge reading in psi. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) under a maximum inlet pressure of 1.0 MPa (145 psi), with a working temperature of -5 to 70 C (non-freezing). The bowl on the 400 size is polycarbonate, and this unit has no mounting bracket included and no reverse/check valve fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and catalogue options for manual or automatic drains, a 40 um standard element, embedded square or external round gauges in MPa, psi or bar scales, G (BSPP) or NPT threads, and mounting brackets. Flow for this series is published as curves 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 filtered, regulated air to the tool-clamp and tool-changer cylinders of a CNC machining centre, where the 5 um element protects directional valves from particulate and the regulator holds a steady setting shift after shift.
Supplying the stopper and diverter cylinders along a packaging conveyor, where one filter regulator per zone keeps water and debris out of the valves and lets each zone hold its own pressure setting.
Conditioning the air feeding valve islands that drive clamps and ejectors on an assembly line, with the differential-pressure drain clearing collected condensate automatically during production.
Pick the size step (200/300/400/600) and port (here 3/8 in, PT) against the flow your circuit needs - we confirm exact figures from the datasheet on request, because flow is published as curves, not a single rating. Within the GFR family you choose the drain: differential-pressure (this unit, and the default), automatic (A) or manual (M); the manual-drain version widens the regulation range down to 0.05 MPa (7 psi). Filter grade is 40 um standard or 5 um with code W, as fitted here. An embedded square gauge is standard and an external round gauge is optional, in MPa, psi or bar scales - this unit carries a round psi gauge. Thread is PT as the standard, with G (BSPP) and NPT as order options, and brackets are optional (this unit is code J, no bracket).
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 number, so we do not quote a figure here. Tell us your operating pressure and the flow your application needs, and we will confirm the sizing from the datasheet before you order.
The GFR400 standard element is 40 um; code W fits a 5 um element. The finer grade suits circuits with sensitive directional valves, instrumentation or air bearings downstream. Both grades are catalogue options on the same body, and this unit is specified with the 5 um element fitted.
