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.

If installing vent in a below grade
foundation, a vent well is needed.

The foundation is critical to the integrity
of the home. That’s why foundation ventilation is
critical. Unventilated foundations are subject to built-up moisture
that can eventually lead to costly damage.
Temp Vent foundation vent systems help protect this critical area
of the home. What’s more, ventilation can help control conditions
that lead to mold, mildew, fungi, damp rot and unhealthy air.
But there’s more. If
there’s one thing termites are attracted to, it’s warm, moist,
dead air environments such as those found under houses in crawl
spaces or unfinished basements. Temp-Vent products have been
especially designed for the pest control industry.
Temp-Vent foundation vents help to provide ventilation that can
reduce moisture in these areas, which helps control termites.

Specifying a
Temp-Vent System
When you recommend Temp-Vent foundation ventilation
products, you can install an automatic, non-powered
foundation vent system or electrical powered
ventilators.
Specifying a Temp-Vent foundation vent system is
simple. All vents are sized to fit 8" x
16" openings with 1” outside frame on each of
4 sides. However, the design of the system and the
number of vents required are different for powered
and non-powered vents.

Power Foundation Vents
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 Specify:
To determine the correct number of Power Temp-Vents, use
the following formula:
1) Multiply the square feet of the crawl space by the height
in feet. This gives the number of cubic feet in the
crawl space.
2) 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.
3) 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.
4) Install 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

Note: The operation of this temp-vent may be loud when
installed in a wood stud wall. To reduce noise, install in a
concrete or cinder block foundation wall, or add insulation and anti
vibration padding.
