KAMAKURA SEISAKUSHO Co.,Ltd. rooftop ventilation fan Roof fan 770Φ Low noise type Three-phase 200V

[Features]
Low noise has been achieved with a wide-wing fan that prevents air flow from dropping.
A roof fan exhausts the hot air that accumulates near the ceiling to improve the work environment.
The average noise is reduced by 4 to 6 dB compared to the standard type.
By adopting a wide blade fan, we have overcome the drawback of the conventional low-noise type, "noise reduction = reduction in airflow", and designed to suppress the reduction in airflow.

[Use]
For ventilation in factories and warehouses.
For ventilation of large-scale stores and large-scale spaces.
