The Balanced Aspiration system (B.A.) is a breakthrough in domestic rangehood appliance technology and features exclusively on Schweigen IN. rangehood models. It is particularly effective with the high-extraction power of the Isodrive® motors.
The system consists of an inner plate with perforated and strategically spaced holes to spread air intake evenly across the filtration zone before it is extracted through the filter.
