The AirTAC GFR40010MC1WT 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR40010MC1WT is an AirTAC GFR400 filter regulator, a single-body unit that removes water and particulate from compressed air and reduces pressure in one pass. This configuration is the size 400 body with a 3/8 in NPT threaded port, a 5 um filter element (the finer W grade, versus the standard 40 um), a manual drain on the PC bowl, and a round pressure gauge with an MPa scale fitted. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and the unit carries a maximum inlet pressure of 1.0 MPa (145 psi) with a working temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of port sizes, PT (standard), G or NPT threads, manual, automatic or differential-pressure drains, 40 um or 5 um filtration, square or round gauges with MPa, psi or bar scales, and a low-pressure regulator option. Flow is published as curves rather than a single rating, so we confirm the datasheet figures for your application on request.

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 0.05 - 0.9 MPa (7 - 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. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |

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 pallet-clamp circuits of a CNC machining centre, where the 5 um element protects the clamping valves from water and fine particulate carried in shop air.
Conditioning the air feeding the pick-and-place and carton-sealing cylinders on a packaging conveyor, with the regulator set to the pressure the cylinder and valve stack were sized for.
Supplying clean, regulated air to lab analysers and pneumatic sample-handling fixtures, where the 5 um grade and a stable setpoint from the regulator protect sensitive pneumatic controls.
Choose the size 400 / 3/8 in port step against the flow your line actually needs, then step up or down a size if the demand sits near the edge of a body. The 5 um element in this model suits air that feeds sensitive components such as valves, cylinders with tight clearances or instruments; the standard 40 um grade is enough for general plant air. The manual drain means someone bleeds the bowl on a routine - pick the automatic drain if the unit sits in an unattended position, or the differential-pressure drain as the default for normally attended installations. The fitted round gauge reads in MPa; psi and bar scales are available, and an embedded square gauge is the standard alternative. PT is the standard thread; G (BSPP) and NPT (as on this model) are catalogue options to order. A mounting bracket is included. Because flow is published as curves and not a single rating, ask us to confirm sizing from the datasheet 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 GFR series as curves, not as a single rated number, so we do not quote a figure here. Tell us your inlet pressure, setpoint and expected air demand and we will confirm the sizing from the datasheet curves for this exact model before you order.
This model has a manual drain: the PC bowl is bled by hand on a routine, which suits attended installations. If the unit will sit where nobody passes regularly, order the automatic drain; the differential-pressure drain is the default choice for normally attended plant air. All three are catalogue options on the GFR400.
