Downdraft Ventilation System

The downdraft ventilation system must include a
blower assembly. (I) models include a 500 CFM
internal blower and (R) models are shipped
without the blower assembly. An in-line or
remote blower assembly must be selected to
accommodate the cooking appliance, CFM
requirements and homeowner preferences. In-
line and remote blower assemblies are available
as sales accessories through your Wolf dealer.
IMPORTANT NOTE:
Use only a Wolf blower
with all Wolf ventilation products.
In-line blowers are mounted in between the
downdraft and the exterior of the home. Remote
blowers can be mounted on the roof or in some
cases, on an exterior wall. Refer to the illustra-
tions below for dimensions of Wolf in-line and
remote blowers.
Cooktop ventilation recommendation charts on
the following page provide minimum CFM
recommendations according to the cooking
appliance and downdraft system used and
blower options for each specific downdraft.
