Zehnder supports tradesmen in the planning of ventilation systems through its expert sales team. The air volumes required for the building are determined on the basis of the latest energy-saving regulations and DIN regulations, allowing the right units to be recommended. Sub-soil heat exchangers, pre-heaters, humidity recovery and source or mixed ventilation are also taken into consideration, depending on requirements. This provides the property developer with a tailor-made offer for a complete ventilation system.

The ventilation tubes can be cleaned as required, although dirt does not normally settle on the smooth inner skin. The unit filters and dust filters in the extract air vents protect against soiling. Pollen filters can be optionally installed in the unit. However, these are only effective in the long term if they are regularly replaced. The heat exchanger should also be regularly cleaned to comply with all hygienic requirements.

  • Smooth inner skin prevents dirt from settling
  • Simple replacement of filters in the unit and the air vents
  • Simple heat exchanger cleaning

Zehnder ventilation units are exceptionally user-friendly and require very little maintenance. They should nevertheless be regularly checked by a specialist, as is the case with all electronic and mechanical products. The unit should be examined for dirt and the heat exchanger must be cleaned. The heat exchanger can be removed from the unit by a specialist and washed out under running water in just a few easy steps. For a Zehnder ventilation unit, this is only necessary approximately every two years and can be arranged affordably – for example, as part of heating maintenance work. A “Major Service” of this kind is mainly intended to keep the units operating and to ensure the long-term effectiveness and efficiency of the system.

Tp ensure perfect operation, the user only has to follow a few simple care points and perform the “Minor Service”. This means that the operator must check the unit filters and the extract air valves in the relevant rooms every 3 months, and replace them if necessary. The filters are easily accessible and users can replace them quickly and easily themselves. We recommend a full filter replacement every six months. Original spare filters can usually be purchased from the installer or ordered easily from our online shop.
