Backward curved centrifugal impellers
To prevent accumulation of dirtiness.
Dynamically balanced. -
Low noise level
Internally lined with 25mm thickness of fireproof acoustic fiberglass insulation (M0) reducing the noise level significantly. -
Robustness
Quality finished aluminium profiles and plastic corners providing a great robustness. -
IP55 external terminal box
To facilitate electric.
