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. 
(Vented vs. Sealed Crawlspaces)

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 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.

CUSTOMER FEEDBACK
Glad to take the time to recognize a level of service that stands out. Have been half-heartedly looked for foundation vent wells for years. The locals that woulda' and shoulda' had them didn't so I knew this task would be governed by one or several of "Murphy's Laws"!

I found them by chance at your site...ordered on-line and rec'd exactly what I expected within a couple of days. I was so impressed I installed both within two days!

Whatever system you have in place is working...more important, the employee(s) who monitor e-orders and start the ball rolling are earning their paycheck(s)...not to mention the rest of those involved in locating, packing and shipping! Again, thank you!

There is also a 1" lip on the outside perimeter of the vent. These sizes apply to both the Series 5 & 6 Make sure you measure first, there is a 30% restocking fee to return these vents. Frequently Asked Questions	Totally enclosed motors feature a 3-prong plug and are 0.01 HP rated (quiet model) or 0.017 HP rated (high output model) for continuous operation. UL recognized and CSA certified. Series 6 is a one-piece vent and Series 5 vents have a removable front grill that can be snapped on after installation. A high output model with a larger motor and a quiet model with a smaller motor are both available. (See specifications.) Power vents should be placed on one side of the house with non-powered vents that act as intake vents, on the other 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.

Thermostats Set at approximately 50° F, the thermostat turns the unit off when the crawl space temperature drops below the setting. Normally, when the temperature outside is at 40 degrees the temperature in the crawl space is approximately 50 degrees. The thermostat helps protect pipes and save energy by turning the vent off when the temperature is close to freezing.
