Product Description

MINI is a single room heat recovery ventilator which performs three functions. First, it supplies fresh air to a space ( ventilation ). Secondly, the fresh air is purified with filters while pollutants are expelled from the space ( purification ). Thirdly, the supplied fresh air is passively heated or cooled depending on the outdoor conditions ( comfort ).
CLIMATE is primarily an exhaust fan that is equipped with a supplementary supply fan for heat recovery and can continuously ventilate single rooms, apartments, tiny houses, and small houses. The portable heat recovery products are visually depicted in Figure 1.

NOTE
The direction of the supply and exhaust air streams are reversed for CLIMATE as compared to MINI.

NOTE
The product shall be used in only indoor spaces.
