AirTAC GFR400-10 Filter Regulator (GFR40010MF1)
The AirTAC AirTAC GFR400-10 Filter Regulator (GFR40010MF1) 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 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 (GFR40010MF1)
The GFR40010MF1 is a genuine AirTAC GFR400-series filter regulator that removes water and particulate from compressed air and regulates downstream pressure in one body. This 400-size unit has a 3/8 in PT port, a manual drain bowl, the standard 40 um filter element, and the square embedded pressure gauge with an MPa scale, so one connection gives you clean air at a set pressure.
It is a genuine AirTAC part from the G-series range, which spans 200, 300, 400 and 600 sizes with automatic, manual or differential-pressure drains, a 5 um element option and G or NPT thread variants. Rated flow is published as curves rather than a single figure, so we confirm the datasheet and flow numbers 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 (GFR40010MF1)
| 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. |

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 (GFR40010MF1) Is Used
Automated assembly station supply
Point-of-use conditioning for a robotic assembly cell: the GFR40010MF1 filters water and chips from the plant air header and holds a steady regulated pressure to the cell's valve manifold, with the MPa gauge giving the maintenance team a clear setpoint reading at the station.
Packaging line air actuation
On a cartoning or case-sealing conveyor line, this filter regulator conditions the 3/8 in branch feeding pneumatic pushers and clamps. The manual drain is opened at shift start and end, and the regulator keeps actuator speed consistent as the header pressure wanders.
Textile machinery air preparation
Installed ahead of loom or knitting-machine air jets and cylinders, the unit strips condensate and 40 um particulate from a humid mill air supply and regulates it to the machine's specified working pressure, with the manual drain serviced during scheduled stops.
Is the AirTAC GFR400-10 Filter Regulator (GFR40010MF1) the Right Unit?
At 400 size with a 3/8 in PT port, this model sits in the upper mid-range of the G-series; step up to 600 or down to 300 depending on the flow your line needs. The manual drain means an operator opens the bowl drain during checks - choose automatic if nobody is regularly at the machine. The 40 um element handles general plant air; pick the W variant for 5 um protection. Gauge scale is MPa here, with psi and bar alternatives available, and the trailing thread code can be G (BSPP) or T (NPT) instead of the PT standard. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application 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 (GFR40010MF1) FAQ
AirTAC publishes flow for the GFR400 series as characteristic curves, not as a single rated number, so we do not quote one figure here. Tell us your line pressure and downstream demand and we will confirm the datasheet and flow curve for this 3/8 in model on request.
The M in the code means the bowl drain is opened by hand - ideal where an operator already visits the machine daily. The same 400-size GFR is also available with an automatic or differential-pressure drain, and note that the manual-drain version carries a wider regulator adjustment range starting lower: 0.05-0.9 MPa (7-130 psi) versus 0.15-0.9 MPa (20-130 psi) for the auto and differential versions.
