| 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.

Temp Vent foundation vent systems help protect this critical area of the home. Ventilation can help control conditions that lead to mold, mildew, fungi, damp rot and unhealthy air.
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
