11.Quiet operation of less than 32.7dB(A).
12.Easy control. Unit can be controlled via button, remote controller and WIFI (Smart APP). With APP, user also can create scene control and group control.
13.Controlled by Android or iOS smartphone via the cloud server from anywhere in the world.
14.Smarter IAQ control. Standard CO2 sensor to display real-time concentration and controls the unit to supply more fresh air to dilute the CO2 concentration, and optional humidity sensor and IAQ detector.
Product Structure
Reversible DC Motor
The reversible axial fan is with EC technology. The fan is characterised by low power consumption and silent operation. The fan motor has built-in thermal protection and ball bearings for long life.

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 prevent the ingress of dust and insects into the supply air and contamination of the fan parts.
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.
ENERGY SAVING
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.
The ventilator operates in the heat recovery mode with two cycles. Two units intake/exhaust air alternately at the same time to achieve balance ventilation. It will increase the indoor comfort and make ventilation more effective. The heat and humidity in the room can be recovered during ventilating and the load on cooling system can be reduced in summer.
