The mixing chamber SKS consists of two parallel dampers operating in antiphase, and one cross (recirculation) damper which allows to carry out air mixing.
The case of the SKS mixing chamber is made of galvanized steel sheet. Rotary plates are made of aluminium profile. The tightness of the damper is achieved due to the rubber seal, which is installed on each rotary plate.
The plates are rotated by a gear drive. The set of the mixing chamber includes three shafts for actuators.
