Product description
The Zehnder EVO 4 is an ultra-flat constant-flow ventilation unit designed for installation in false ceilings or walls in new-build and renovation projects. It provides balanced ventilation using centrifugal fans with forward-inclined blades to ensure low noise and high efficiency. Available with a heat recovery (HRV) or enthalpy energy recovery (ERV) exchanger for partial humidity recovery, and an optional built-in 1 kW electric preheater.
