Applications
The mixing chambers is designed for mixing (recirculation) of extract and intake air in a required ratio.
Design
The housing made of galvanized steel. The dampers with aluminium blades driven by plastic gearwheels.
Extract and supply air dampers are interconnected with one shaft and are opened synchronously with a single actuator. The recirculation damper is opened by a separate actuator.
SKRA is equipped with two 24 V actuators for air flow control. Both actuators are driven by 0-10 V input voltage from 100% recirculation to 100% fresh air.
Mounting
Standard connection flange for rectangular air ducts or other ventilation system components.
Fixation with galvanized bolts and clamps. The mixing units are suitable both for indoor and outdoor installation in any operating position. Service access to the actuators must be provided.
