The diameter of the housing of the working module: 340 mm
Diameter of the mounting hole: 350 mm 
The volume of air exchange during recuperation:
Inflow: 1100 m3 / h 
Exhaustion: 1020 m3 / h 
Performance coefficient: 78-48% 
Electricity consumption: from 80 W / h to 310 W / h 
(depending upon the mode of operation). 
It is possible to connect the recuperator to the system of ramified 
inflow and exhaust channels (ΣΔР ≤ 350Pa).

Also, the system can be made both for installation in the wall, 
and for placement inside the room. The ventilation system is controlled using 1-2 dimmers (standard equipment), or profes-sional control units (is completed to order).
