B/D units with capacitor motor, air flow direction switchable. Reversing mode with approx. 35 % lower volumetric flow. B unit capacitor ready for connection. D unit capacitor in separate terminal box, pre-wired.
E-units with shaded-pole motor, one air flow direction, no reversing mode.

DZQ ... / DZS …: Three-phase AC versions of
B/D units with three-phase AC motor, air flow direction switchable. Reversing mode with approx. 35 % lower volumetric flow.
