Ventilation system MBESx

The ENERVEX Modulating Building Exhaust System™ (MBESx) is a demand-controlled ventilation system designed for multi-story buildings with multiple kitchen hoods, bathrooms or clothes dryers on multiple floors. Rather than having a large numbder of individual exhaust ducts for each appliance, or a fan that operates at full speed 24/7, the MBESx senses when appliances are running and modulates with the load. It assures proper exhaust rates at any time no matter the demand. Can reduce the exhaust rate of conditioned air by up to 60-70%. In addition the BEFx fan is ultra-efficient with high-efficiency housing design and a IE5 highly-efficient EC-motor.
