Vent-A-Hood® Magic Lung® Whisper Quiet Technology

The patented Magic Lung® blower system sets Vent-A-Hood’s kitchen ventilation systems apart from all other range hoods and range canopies. The Magic Lung has become an industry standard in range hood blower technology, and stands up against the rest.

Here are 5 top reasons to purchase a stove top vent with the Magic Lung over any other brand:

Quiet

Turn on a Vent-A-Hood® and you’ll hear only a whisper of air movement, because the Magic Lung® system provides the quietest kitchen ventilation available. Vent-A-Hood®s with the Magic Lung® range hood technology also feature SensaSource®. SensaSource® raises the blower speed from low to high based on temperature for optimal grease control, fire safety, and even quieter operation.

Efficient

The powerful Magic Lung® blower traps all cooking contaminants, liquefies grease vapor, and removes heat-polluted air. The Magic Lung® blower combines sufficient air pressure and constant speed with centrifugal filtration. Because it doesn’t pull air through a filter it is the most efficient kitchen ventilation available today.

Easy-Cleaning

The Magic Lung® housing snaps apart for easy cleaning in the dishwasher or with warm, soapy water. Moreover, the Magic Lung® is the only ventilation system that collects the grease in an easily cleaned housing rather than in hard-to-reach areas behind a mesh or baffle filter.

Fire-Safety

The Magic Lung® is the only residential kitchen ventilation system on the market today that prevents fire from spreading to the rest of the home. Constant speed creates centrifugal pressure that prevents fire from entering the ductwork. As needed, SensaSource® increases blower speed to its normal level to maintain this safety feature.

Powerful

Magic Lung® blowers can be configured to provide the power you need for even the most demanding residential cooking surfaces. Each highly efficient Magic Lung® blower supplies ample CFM of air movement. Multiple blowers can be combined in a single Vent-A-Hood® to create the perfect kitchen ventilation for your cooking surface.
