AirTAC GFR400-10 Filter Regulator (GFR40010MC2W)
The AirTAC AirTAC GFR400-10 Filter Regulator (GFR40010MC2W) 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.

About the AirTAC GFR400-10 Filter Regulator (GFR40010MC2W)
The AirTAC GFR40010MC2W is a filter regulator: filtration and pressure regulation combined in one body, with a drain bowl and no lubricator. This 400-size unit has a 3/8 in PT port, the fine 5 um filter element (the W option), a manual drain and a round pressure gauge scaled in psi. Maximum inlet pressure is 1.0 MPa (145 psi) and the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), the wider range that applies to manual-drain units. The bowl on 400 size is polycarbonate (PC) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GFR400 series. Across the G series you can choose 200, 300, 400 or 600 sizes, PT, G (BSPP) or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um elements, embedded square or external round gauges in MPa, psi or bar scales, and a bracket (included unless the J no-bracket option is ordered). AirTAC publishes flow as curves rather than a single rated figure, so ask us and we will confirm the datasheet and sizing 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.
Model Code: AirTAC GFR400-10 Filter Regulator (GFR40010MC2W)
| GFR400 | G-series filter regulator, 400 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". This body offers 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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.

Where the AirTAC GFR400-10 Filter Regulator (GFR40010MC2W) Is Used
Process valve actuator feed
Supplies filtered, regulated air to pneumatic actuated valves on a process skid, where the 5 um element keeps fine debris out of positioner and solenoid pilot air.
Lab automation air supply
Conditions the air feeding pipettes, grippers and small actuators on a laboratory automation line, holding the set pressure read on the round psi gauge.
Fixture clamping on assembly line
Feeds the clamping cylinders of modular fixtures on an assembly line, delivering clean air and a regulator setting the cell can rely on shift after shift.
Is the AirTAC GFR400-10 Filter Regulator (GFR40010MC2W) the Right Unit?
Step the size and port against the air your line actually uses: 200, 300, 400 and 600 step up in both port size and flow capacity, with this 400 size at 3/8 in PT. Drain choices are differential-pressure (default), automatic or manual - the manual drain on this unit also widens the regulating range down to 0.05 MPa (7 psi). The W in this code selects the 5 um element over the 40 um standard, the right choice when downstream valves or instruments need finer prefiltration. This code carries the external round gauge scaled in psi. PT is the standard thread, with G and NPT as catalogue options to order, and a bracket is included. Flow is published as curves, not a single rating, so ask us to confirm sizing against the datasheet before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" here)
- ✓ Element 40 µm or 5 µm
- ✓ Drain sets the regulating band
- ✓ Gauge fitted, shape and scale
- ✓ Thread PT, G (BSPP) or NPT
- ✓ Oil needed downstream? Use GFC instead
Installation & Maintenance Notes
- check Mount vertically, bowl down, following the airflow arrow.
- check One body does the filtering and the regulating — no separate regulator needed.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Adjust only within 0.05 - 0.9 MPa (7 - 130 psi).
- check Drain condensate before the bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
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 GFR400-10 Filter Regulator (GFR40010MC2W) FAQ
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we do not state one number here. Share your line pressure and required air consumption and we will confirm the flow curve and sizing against the datasheet on request.
The W in this code selects the finer 5 um element instead of the 40 um standard, which suits circuits with sensitive pilot valves, positioners or instruments downstream. If your application only needs general water and particulate protection, the 40 um version of the same unit is the more common choice; we can confirm the right grade against your datasheet on request.
