How the LG-Z-M-LB works.

Decentralised ventilation units in the floor for buildings glazed from floor to ceiling. They supply the minimum outdoor air and remove internal cooling and heating loads; the LG-ZUM-M-LB adds recirculation. The air principle is mixing ventilation: a fan of its own, no induction. In the collection they are listed under Façade and floor systems.

Applications: office and administration buildings (krantz.de).
