AirTAC GFR400-10 Filter Regulator (GFR40010MJF1W)
The AirTAC AirTAC GFR400-10 Filter Regulator (GFR40010MJF1W) 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 (GFR40010MJF1W)
The AirTAC GFR400-10MJF1W is a G-series filter regulator: filtration and pressure regulation combined in one body. The W suffix selects the finer 5 um filter element instead of the 40 um standard. This configuration is the 400 size with a 3/8 inch PT port, a manual drain bowl in polycarbonate, and a square embedded pressure gauge reading in MPa. The J position means no mounting bracket is included.
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with drain type, element grade (40 um standard, 5 um W), gauge style and MPa/psi/bar scale, and PT, G or NPT thread options. Flow figures are 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.
Model Code: AirTAC GFR400-10 Filter Regulator (GFR40010MJF1W)
| 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. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. 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. |
| (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 (GFR40010MJF1W) Is Used
Analytical instrument air panels
Feeds pneumatic valves and sample-handling actuators on analytical and laboratory equipment, where the 5 um element gives finer particulate protection ahead of sensitive pneumatic components.
Powder coating and finishing gun supply
Conditions supply to air-driven finishing equipment on a coating line, where the finer 5 um element helps protect spray and metering components from finer particles, with the drain bled between batches.
Pneumatic control panel conditioning
A single-body conditioning point in a control panel supplying positioners and pilot valves, where the gauge gives a visible set pressure and the 5 um element suits pilot-grade air.
Is the AirTAC GFR400-10 Filter Regulator (GFR40010MJF1W) the Right Unit?
Choose the W grade when downstream valves, cylinders or instruments need finer protection than the standard 40 um element provides; note that a 5 um element loads up faster and suits clean, dry-ish lines. The manual drain allows the wide 0.05-0.9 MPa (7-130 psi) regulation range, while automatic or differential-pressure drain versions are limited to 0.15-0.9 MPa (20-130 psi). Match the 400 size and 3/8 inch PT port to your circuit's air demand and confirm the step against required flow. The square gauge reads MPa; psi or bar scales are catalogue options. PT is the standard thread, with G (BSPP) and NPT orderable, and no bracket is included with this J-suffix code.
Flow is published as curves, not a single rated number, 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 (GFR40010MJF1W) FAQ
AirTAC publishes GFR400 flow data as performance curves, not as a single rated figure, so no rated flow number is stated here. A finer 5 um element also behaves differently in service, so send us your application details and we will confirm the flow and datasheet figures for this model on request.
The W suffix changes only the filter grade: 5 um instead of the 40 um standard. Choose it where downstream valves, instruments or finishing equipment need finer particulate protection, and expect the element to load sooner. The rest of this code - 400 size, 3/8 inch PT port, manual drain, square MPa gauge, no bracket - is unchanged from the non-W version.
