This unit requires 3 x G4 panel filters for the supply and extract air filtration. An optional F7 filter can be used on the air supply.
The Komfort EC SB 350 features a polystyrene counter-flow heat exchanger, it has a large surface area allowing for high heat recovery efficiency ranging from 85% to 98%.
A drain pan is situated under the heat exchanger to collect any condensation, it is fitted with a drain pipe for condensate removal.
The unit has an electronic freeze protection system that prevents the heat exchanger from freezing in cold seasons. If the temperature senses temperatures that are very cold, the supply fan turns off allowing the heat exchanger to be warmed by the extracted air. After the freezing danger is over, the supply fan is activated, and the unit runs in standard operation mode.
The Komfort EC SB comes with an integrated control system with a S14 wall mounted control panel. A 10m cable is supplied with the unit to connect the control panel.
