Domovent Solo RA1-35-L07-9 R

Design
Fan
Air is supplied or extracted by a reversible axial fan with an EC motor. Due to EC technology the fan is distinguished with low energy demand. The motor has overheating protection and ball bearings for longer service life.
Air filters
Two built-in filters with total filter class G3 are used to clean supply and extract air flows. The filters ensure fresh air cleaning of dust and insects and prevent the ventilator parts from soiling. The filters are cleaned either with a vacuum cleaner or flushed with water.
Energy heat exchanger
The high-technology energy heat exchanger is used for extract air heat energy recovery and supply air heating.
The Solo RA1-35-9 R is equipped with a ceramic energy heat exchanger with recovery efficiency up to 85 %.

Operation logic
Energy is recovered due to reversing operation of the ventilator, which consists of two cycles:
CYCLE I. As warm stale extract air flows through the ceramic heat exchanger, it heats up and moisturizes the heat exchanger. In 70 seconds as the ceramic heat exchanger gets warmed the ventilator automatically switches to Air Supply mode.
CYCLE II. Fresh, cold intake air from outside flows through the ceramic heat exchanger, absorbs accumulated moisture and is heated to the room temperature. In 70 seconds as the heat exchanger gets cooled down, the ventilator switches to Air Extract mode and the cycle is renewed.
The Air Supply and the Air Extract modes are switched every 70 seconds.
