Backward curved hollow profile blades


Unparalleled system efficiency for plug fans:
The Evo series sets a new standard in efficiency. No other plug fan reaches higher system efficiency.

Innovative blade and impeller shaped for highest efficiencies
The entire shape of the impeller was optimised using a real turbulence profile for the blades. This ensures that the impeller reaches as yet unparalleled high efficiency and takes the top position in aerodynamics.
