Bidirectional ventilation unit with heat recovery “PRANA” is a monoblock ready for use in
accordance with design and assembly tasks and conditions.
The system is mounted in a hole of the appriate diameter in the upper part of the wall
adjoining the outside, at a distance of no less than 100-150 mm from the ceiling or walls. The
through hole should be a slope of 3-5 degrees towards the outside. The operating module of
the ventilation unit is mounted in the hole using a seal (Fig. 4).
The length of the working module should correspond to the thickness of the wall in which
the installation will be carried out. In order to ensure the normal operation of the system, it
is necessary that its body facing the the outside extends beyond the wall by 1-2 cm to the
beginning of the air intake (Fig. 4).
