The Jet Fan
can also help when there is an unexplained humidity problem in
the attic. Humidity can cause frost and ice to accumulate on the
roof-framing members and eventually cause mold, mildew and rot
to damage your home's framing. An optional humidistat turns the
fan on and off regardless of temperature whenever the relative
humidity is too high in the attic.
Jet Fans
come in two different sizes. The model 727 Fan covers up to 2300
square feet of attic floor, and the model 747 up to 3200 square
feet. For efficiency, bigger is not necessarily better. Jet Fan
Installations will check your intake ventilation so your attic
ventilation system is balanced with maximum cross-flow through
the attic.

Standard
installation includes up to four (4) additional roof intake vents
and a shut-off switch located inside the attic access (optional
wall switch available). For attics with unexplained signs of excess
humidity, an optional humidistat is available.
