Helios Fans ZEB EC

The Helios Fans ZEB EC is a compact central ventilation unit featuring four intake spigots and one discharge spigot for efficient air distribution. Constructed from impact-resistant light grey plastic, the housing is both durable and lightweight. Three inlets and the outlet are compatible with duct sizes NW 100 and 125, with four reducers included. An additional inlet supports NW 100, 125, and 160, with an asymmetric reducer from NW 160 to 125 provided.

The unit operates quietly thanks to a steel centrifugal impeller housed in an aerodynamically optimised scroll. Air is drawn in via a smooth bell mouth inlet. The electronically commutated (EC) DC motor provides high energy efficiency, even under speed-controlled conditions. It features a ball bearing-mounted external rotor design for maintenance-free, interference-free continuous operation.

Fan speed can be adjusted via potentiometer or universal control systems (available as accessories), and three-step speed control is possible using the optional DSZ switch. DIP switches on the integrated drive electronics allow for customisable performance settings.
