Low noise fan boxes
from 200 to 7.000 m³/h

The SIL series fan unit, fitted with a relevant thickness of noise attenuation material, allows an extremely silent operation.
This series is composed of five direct driven fan models.
With its different combination of fan size, fan speed and power supply, these units cover up to 7.000 m³/h airflow rate range and up to 500 Pa static pressure range.
The high external static pressure lets SIL units operate in very long air ducts.
