Environmental Interference with Downdraft Ventilation

Are there Drafts, Air Movement, or Restrictions in the Room?

Other air movement devices, such as ceiling fans, air conditioner registers, etc., can create air currents that interfere with downdraft ventilation.

Make-up Air

The air that is exhausted by the unit must be replaced. If a room or house is too "tight," the unit may not vent properly. If a house or room is too "tight," it will be necessary to introduce more air into the environment. Some air conditioning and heating units allow for make-up air.

Adjacent Cabinets

Cabinets closer than the minimum distance allowed can create dead air pockets that impair performance. The recommended distance to adjacent cabinets or walls is 6" for maximum performance.
