The Magic Lung® blower system is designed so that if the motor is running properly, the system will liquefy grease in the sealed blower housing and create a pressure barrier, lowering the risk of an attic or wall fire. In 70+ years of manufacturing this system, Vent-A-Hood® has never received a report of an attic or wall fire when the Magic Lung® blower has been in use.

How To Choose the Right Ventilation System.

 

To help you chose the right ventilation system for your kitchen, we suggest you determine the appropriate answer to the following questions (listed below each question) to help focus your search. That is, finding the Vent-A-Hood® that is appropriate for your needs—and identifying the size and blower specifications you’ll need when ordering. At the conclusion of this process, you will have matched your cooking equipment with the appropriate range hood. Note: Additional specification considerations may be required for outdoor cooking equipment.


What type of cooking equipment do you have?
o Standard electric
o Standard gas
o Professional style

What type of hood do you need?
o Wall-mount
o Under-cabinet
o Island
o Liner insert (wall-mount or island)

What size of Magic Lung® blower do you require?

There's no exact science for determining your blower requirements-if you never have all your burners on at once, you don't need to buy excessive capacity. To locate on the following chart the Magic Lung® blower that's appropriate for you, consider the type of hood you want, the type of equipment you use, and your cooking habits-whether you use all or only part of the BTU/WATT value of the cooking equipment. Note: Multi-burner cooktops are not generally operated at full capacity, whereas BBQs, woks, and griddles are often operated at full capacity.

 

Because the Magic Lung® uses centrifugal filtration units rather than conventional baffle or mesh filters, the Magic Lung® blower can handle cooking equipment with higher cubic feet per minute (CFM) requirements—and can deliver equivalent CFM much more efficiently than other filtration systems. When comparing the Magic Lung® with blower units made by other manufacturers, use the “Equivalent CFM.”

What height hood do you need?

Whatever your kitchen’s ceiling height, Vent-A-Hood® can meet your needs. The bottom of a wall-mount or island hood should generally be mounted 30" above the cooking surface, but an under-cabinet hood requires less space (24"–27" for a 9" hood, 21"–24" for a 6" hood). Be sure to account for the height of anything that will be above your Vent-A-Hood, such as a soffit, a cabinet or a duct cover.
• 6" (under-cabinet)
• 9" (under-cabinet)
• 18" (wall-mount or island)
• 30" (wall-mount or island)
• Other.

What width hood do you need?

Wherever possible, the width of under-cabinet and wall-mount hoods should overlap the burners 3"– 6" on each side. Island hoods must overlap by 3"– 6" for proper performance.
• 30"
• 36"
• 42"
• 48"
• 54"
• 60"
• 66"
• Other.

What depth hood do you need?

The hood should be deep enough to fully cover all burners.
• Under-cabinet:
• 19-1/2" or 21" (standard)
• Other.
• Wall-mount: 24" (for standard and most professional cooking equipment),
• 27" (for some professional cooking equipment) or other
• Island hood: 27" (for standard cooking equipment), 30" (for professional cooking equipment) or other.

How do you need to duct your hood?
• Top vent—the standard ducting location for all Vent-A-Hoods®.
• Back vent—under-cabinet SLH6-K model and 30" tall wall-mount hoods may be top or back vented. Selected 18" tall wall-mount hoods may be equipped for back venting; this must be specified at the time of the order and additional charges will apply.
