DESIGN AND OPERATING LOGIC
The ventilator consists of decorative protecting internal grille, a cartridge, an air duct with a sound absorbing material and a protecting
external ventilation grille.
Cartridge is the basic functioning part of the ventilator.
The cartridge consists of a fan, a regenerator and two filters that ensure rough air filtration and prevent ingress of dust and foreign
objects into the regenerator and the fan.
The internal grille is equipped with manually actuated shutters to close the air duct during the ventilator standstill.
The ventilation hood on the outer wall prevents ingress of water and foreign objects into the ventilator.
Cartridge is a block consisting of removable
filters and a solid fan-regenerator unit.
The filters are easy removable for technical
maintenance.
