Very high efficiency

Thanks to:

1. the new steel impeller with 11 backward curved blades;
2. the precision-engineered inlet cones fitted with the innovative ForeFinger ®;
3. the integrated design of the trapezoidal cut-off was developed to work with ForeFinger ®.

You get:

1. increase airflow and pressure. For the required volume and pressure, the fan can now run at a lower speed or you can select a smaller fan.
2. more uniform flow at the fan outlet. This can result in better filter and coil efficiency in the air handling unit.
3. wider working field with high efficiency. This means more flexibility.
4. significant reduction of noise generated by the blades, especially in the low-frequency range.

The performance data are under DIN 24166 CLASS 1.
