Ceramic Energy Regenerator
The high-tech ceramic energy accumulator with a regeneration efficiency of up to 97% ensures heat recovery from the exhaust air to heat or cool the supply air flow. Due to its cellular structure, the unique regenerator has a large air contact surface and high heat conducting and accumulating properties.
The ceramic regenerator is treated with an antibacterial composition to prevent bacterial growth inside.
Air Filters
Two integrated air pre-filters and a F7 air filter are fitted as standard to provide supply and extract air filtration.
The filters are also antibacterially treated.
The filters are cleaned with a vacuum cleaner or by flushing with water.
The antibacterial solution will not be removed.


The ventilator operates in the heat recovery mode with two cycles can save energy by over 30% compared with the normal exhaust fan. The heat recovery efficiency is up to 97% when the air first entering the heat regenerator. It can recover the energy in the room and reduce the load on the heating system in winter.
