OverviewThe Vitoair FS is a compact central mechanical ventilation unit with enthalpy heat recovery and humidity control designed for detached houses and residential buildings. It delivers up to 300 m³/h, ensuring balanced indoor climate, reduced energy demand and intuitive operation via the ViCare app.
Main features- Air flow rate: 300 m³/h
- Heat recovery up to 80 % via enthalpy (recuperative) heat exchanger with polymer membranes
- Balanced humidity management (heat and moisture recovery)
- Compact design with 245 mm installed height for ceiling, wall or horizontal installation
- Connector arrangement: right‑hand or left‑hand version
Benefits- Lower heating costs due to high heat recovery
- Low electrical consumption with EC constant volume fan
- Improved indoor air quality and filtration — suitable for allergy-sensitive occupants
- Reduced noise and enhanced security by allowing windows to remain closed
- Balanced humidity helps prevent mould and building damage
- No condensate drain required, simplifying installation
- Remote monitoring and straightforward commissioning by trade partners
System integrationCompatible with Viessmann One Base and can be combined with Vitodens gas combi boilers or Vitocal heat pumps. Optional integration with Vitovolt photovoltaic systems and Vitocharge VX3 storage enables extended self-consumption and energy management.
Special features- Very compact and quiet: installed height 245 mm with max. air flow 300 m³/h
- Enthalpy heat exchanger with polymer membranes recovers both heat and moisture while providing a microbial barrier
- Flexible installation: under-ceiling, on-wall or horizontal in attic; connector layout adaptable to site conditions
- No condensate drain required; connector arrangement available for right‑hand or left‑hand installations
Control options- ViCare app — full system control (no additional accessories required)
- Four-stage pushbutton with filter change indicator
- Wireless remote control: Vitotrol 300-E (plain text display)
