The AirTAC GFR40010C3WT AirTAC Filter Regulator NPT3/8 5 um is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/8" 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 GFR40010C3WT is an AirTAC GFR400 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate down to 5 um and holds a regulated downstream pressure adjustable from 0.15 to 0.9 MPa (20-130 psi). This configuration has a 3/8 in NPT port, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, a polycarbonate bowl, and a round pressure gauge reading in bar. A mounting bracket is included and the unit is the standard (not low-pressure) type.
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of drain types, 40 um or 5 um filtration, gauge styles and scales, and PT, G or NPT threads. AirTAC publishes flow as curves rather than a single rated figure, so ask us to confirm flow and 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.

| C | Gauge shape: Round. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 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.

Filter and regulate the air feeding directional control valves on a carton-forming and sealing line, with 5 um filtration protecting spool clearances and the bar gauge giving operators a visible setpoint.
Supply pusher and gate cylinders on a bottling conveyor: the regulator holds consistent cylinder force for repeatable stroke timing, and the differential-pressure drain handles condensate during continuous running.
Feed a multi-station assembly cell's air manifold through this 3/8 in unit, so every actuator downstream sees the same filtered, regulated pressure, with the included bracket allowing panel-side mounting.
Size 400 with a 3/8 in port sits in the middle of the GFR range: step up or down (200/300/400/600) according to the flow your line needs, and match the port to your piping. Choose the 5 um element (this model, code W) where downstream valves and cylinders need finer protection than the 40 um standard; the differential-pressure drain suits continuous-flow duty, while automatic or manual drains are available for intermittent or attended installations. The round gauge here reads in bar; embedded square gauges and MPa or psi scales are the other options. NPT is the thread on this unit; PT and G (BSPP) are orderable alternatives, and a reverse/check valve can be specified if backflow protection is needed.
Because flow is published as curves rather than a single rating, we cannot quote one number here - 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 flow for the GFR400 as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and required flow, and we will confirm the figures from the datasheet on request before you order.
The W in the code GFR40010C3WT selects the 5 um element instead of the 40 um standard, giving finer protection for downstream valves and cylinders. The blank drain position selects the differential-pressure drain, which discharges collected condensate automatically as air flows through - no manual draining during production. If your duty is intermittent, automatic (A) or manual (M) drain versions are available in the same series.
