Filterupgrade for MVHR Systems, private home filtration
HS-HomeAir is a standardized, easy-to-install upgrade solution for residential ventilation that provides maximum air quality at cleanroom level through a multi-stage filter system.
HS-HomeAir has an intelligent pressure control system that supports existing systems in overcoming the additional filter resistances. In contrast to existing systems, filters with the highest separation performance can thus also be operated without any problems. HS-HomeAir delivers only as much air as the existing MVHR unit requires. This means that usually no changes need to be made to the settings of the existing system during installation and energy consumption remains as low as possible.
HS-HomeAir can be equipped with different filter types in order to offer perfect protection against pollen, odours, smokes, pesticides or even chemical or even radiological air pollution. The filter mount and sealing of the filters comply with the standards appropriate for the protection of hazardous substances. Due to the larger filter surfaces, the design of the filters allows a much longer service life than with the usually filters of the existing MVHR units.
HS-HomeAir offers the following advantages:
- significantly higher filter efficiency against fine dust and particles (up to EN1822 class H14)
- filter whose specification also corresponds to the actual performance,
- Secure sealing of the filter holder by 4-point contact clamping (no cheap slide-in rails which favour leakage flows).
- generously dimensioned filters for longer service life and greater efficiency
- avoidance of overflow effects, as the filters do not filter supply and exhaust air at the same time as often seen with MVHR systems,
- powerful activated carbon filters can be used whose adsobtion goes far beyond the discrimination of odours.
The following filter stages are provided in the standard oder package:
- Prefilter HS-Z-Panel ISO Coarse 80%
- Fine dust filter HS-Beta Pak 85 ISO ePM1 70%
- Particle filter HS-Mikro SF EN 1822 H13
- Activated carbon filter HS-Carbo Panel (against unpleasant odours in the outside air)
