An axial fan for wall mounting with a brushless motor and protective grilles on both sides of the blade assembly. The FPT400A is a variant of the series' 400mm model with an additional reinforced flange edge, built for installations where the mounting is subject to greater mechanical stress.

The brushless motor is prepared for voltage regulation and is protected against overheating via a built-in temperature sensor in the windings. The fan is rated to protection class IP44 and withstands demanding operating temperatures and humidity.

What does the reinforced flange edge add on the FPT400A?

Unlike the standard FPT400 model, the FPT400A has an additional reinforced edge around the mounting flange, giving better resistance to deformation when installed in wall openings that are not perfectly even or where the fan is subject to repeated mechanical stress. The motor and blades are made of pressed sheet metal, the same robust material choice as the rest of the series.

Does the FPT400A retain the same performance as the standard model?

Yes, airflow, power, noise level and electrical specifications are identical to the FPT400: 4500 m³/h at 170 W and 65 dB. The reinforcement only affects the mechanical strength of the flange, not the fan's air performance or energy consumption.

When should you choose the FPT400A over the standard FPT400?

The FPT400A is the right choice for installations where the mounting flange risks mechanical stress, for example uneven wall openings, temporary fixings or locations with vibration in the structure. In other cases, where the standard flange is sufficient, the FPT400 performs equally well at a lower cost.

Frequently asked questions (FAQ)

Is the airflow of the FPT400A lower than the standard FPT400 due to the reinforced flange?

No, the FPT400A delivers exactly the same airflow as the FPT400, 4500 m³/h at 170 W. The flange reinforcement is a mechanical detail that does not affect the fan's aerodynamic performance.

Can the FPT400A be installed using the same fixings as the standard model?

Yes, the mounting dimensions of the FPT400A are essentially the same as the FPT400 (400 mm diameter, same depth and fixing spacing), meaning it can replace the standard model on installation without needing to alter the duct opening.

What sets the FPT400A apart from the standard FPT400 in practice?

The only difference is the additional reinforced flange edge on the FPT400A, which gives better mechanical resistance when installed in demanding or uneven wall openings. Airflow, power, noise level, protection class and the remaining electrical specifications are identical between the two models.
