Powered Temp-Vent
Series 6 (One Piece Construction)
Powered Temp-Vent
systems are designed for foundations that
require a higher rate of airflow and for areas
that are difficult to vent. Depending on the
model they can move large amounts of air per
hour. Designed to run continuously on a low
speed, they draw minimal electricity. However,
Temp-Vent recommends power vents be fitted with
a thermostat and a humidistat to control the
operation of the vent.

To determine the correct
number of Power Temp-Vents, use the following
formula:
-
Multiply
the square feet of the crawl space by the
height in feet. This gives the number of cubic
feet in the crawl space.
-
Multiply
the cubic feet in the crawl space by the
number of air changes per hour desired (4-6
is the recommendation). This gives the total
number of cubic feet of air that has to be
moved per hour to produce the desired number
of air changes.
-
Divide
this number by either 7,200 or 11,160 —
depending on which model is being used —
to obtain the number of power vents needed.
-
Install
Automatic vents to provide air intake on one
side of the foundation with the power vents
on the other side to create a system of
intake and exhaust.
Calculating how many foundation vents are
needed.
Example: 1500 square foot crawl space
x 3 feet high = 4500
4500 cubic feet x 6 = 27,000 / 7,200 = 3.74
Install 4 power vents with intake vents on the
opposite side
Power vents should be placed on one side of
the house with non-powered vents that act as
intake vents, on the side.
A Thermostat should be used to turn
the fan off in freezing weather to protect pipes
under the home and save energy. A Humidistat
should also be connected to the fan to control
the operation of the vent. A damp weather
shut-off humidistat will turn the unit off when
it's raining outside.
A Duct System is available that attaches to a
powered foundation vent to provide targeted
ventilation in hard to reach areas.
