Every time an exhaust fan removes air from your
home an equal volume of air must enter, this is
called makeup air. Homes today are built to tighter
standards resisting infiltration from outside air.
With little to no leakage in the building envelope,
where does a powerful range hood get its makeup
air? If the home does not have enough random air
leaks around the windows and doors, the makeup
air is often pulled backwards from the chimney or
water heater flue, this is called backdrafting. Since
flue gasses from some combustion appliance can
include carbon monoxide, backdrafting is dangerous
and in some cases can be life threatening.
The Fantech Makeup Air System relieves this
problem by introducing positive pressure, balanced
makeup air direct from the outside. The system can
be tailored to your requirements and interlocked
with your range hood to supply the same volume
of air as that exhausted from the range hood, to
achieve "balanced ventilation". Your range hood
fan efficiency and the capture and containment of
cooking odors is dependent on the makeup air!
Most building codes now require makeup air for
kitchen range hood fans that exhaust over 400 cfm.
However, it’s not only large range hood fans that
depressurize the home, large open fireplaces, large
bathroom fans, clothes dryers and power vented
appliances all contribute to the depressurization
of the home, the Fantech Makeup Air System can
be used to balance the exhaust air from these
appliances.
The Fantech system can be tailored to meet your
requirements, based on ventilation demand and
geographical area.
Makeup Air Fans
Components
Supply fans provide nesessary filtered and conditioned makeup air
to the home equal to the amount of air being exhausted.
Components of the makeup air system handle the
outside air when required and don't allow any air to
leak when not in use.
