The Importance of Cooking Ventilation
The main purpose of cooking ventilation is to capture the
by-products of cooking. These by-products are heat, steam,
smoke, odor, hazardous gases, and grease. Without proper
cooking ventilation, these by-products can cause a great deal
of harm to the home. Vent-A-Hood® range hoods exhaust
all cooking by-products to the outside with the exception of
GREASE, which is collected by the patented Magic Lung®
blower system.
The Magic Lung Blower® - How It Works
The Magic Lung® internal blower system was originally patented
in 1937. The Magic Lung® pressurizes grease-laden air as it
passes through the blower wheel and cools the grease from a
vapor into a liquid. The centrifugal action of the Magic Lung®
traps 99% of cooking grease without the use of messy and
inecient wire mesh or bae lters. The constant speed
centrifugal blower is also designed to create a pressure barrier,
lowering the risk of an attic or wall re.
