Help protect your foundation with Crawl Space Temp-Vent. 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.
Crawl Space Vent 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.
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.
A crawl space dehumidifier with no drain or power needed!
| Target Pest(s): | mold, mildew, fungi, damp rot, and unhealthy air. |
| Manufactured By: | Temp-Vent |

| Features: |
A heavy duty coil for dependable operation. |
| Model No.: | Series 6 vents (TV6) |
Whenever possible, vents should be placed on all sides of the foundation. This will create an intake/exhaust system that delivers a steady flow of air. One vent should be installed for each 8 to 10 feet of foundation wall.
Most building codes require 1 square foot of open ventilation area for every 150 square feet of crawl space. Temp Vent Automatic Foundation Vents have 50 inches of net free area per vent. Therefore, you should install one vent for every 50 square feet of crawl space.
For crawl spaces with polyethylene installed, on 80-90% of the ground, the ventilation requirement changes to 1 square foot of ventilation for every 500 square feet of crawl space with a minimum of 4 vents installed to provide cross ventilation. For crawl spaces with polyethylene, install at least one vent for every 500 square feet of crawl space.
The non-powered, Automatic Foundation Vent will open and close automatically using a heat/cold sensitive coil. The louvers open completely at approximately 72 F and completely close at approximately 38 F. Unlike manual vents that can waste energy when no one remembers to open or close them, these vents self-adjust all year long.
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.
Please refer to and follow the instructions on the Product label.

The pests in our house made nests in the crawl space. It was humid and dark. So, as per the professional advice we used spray and it was okay for a few days. But they came again and started nesting. Then we had found that we did not have any crawl space protection. So we bought crawl space vent from the pestmall, it is a really good vent. It seems that our pest problems are finally solved.

I needed a one-piece temp vent for my crawl space because I was going to store some temperature sensitive things in the basement. I researched the existing products in the market and my choice was the pestmall product.

We needed a crawl space vent. So we asked the exterminator for options and he said to buy from pestmall. It was worth the money. This vent system is very effective.
(5/5) Review by Gerald K (Posted on )About a year ago I found out that I had a small termite problem. I was rather shocked and asked the exterminator what I can to do stop them from coming back. He told me that they probably came in from under the house looking for moisture and that I should install a crawl space vent to keep the moisture levels down. I decided on the Temp-Vent crawl space vent because it was relatively inexpensive, it was easy to install and I haven’t seen any termites again.

It was long since I have been experiencing fungus problems in my crawl space and basement. It was because of the moisture. Crawl space vent was a crying need.

(5/5) Review by Peggy Corbett (Posted on )I am used to work in my basement. But the air there did not smell very good. And some dump feeling was along with that. So, I asked around my friends. One was in the constructions, he told me to use a crawl space vent to control the moisture. And I did. It does not smell anymore down there.

(5/5) Review by Ray P (Posted on )crawlspace mold
I’ve had a problem with moisture in my basement and crawl space for the longest time. This had caused a few pest control problems. Someone suggested that I purchase a crawl space vent and I bought the Temp-Vent variety because it had such good reviews. My basement and crawl space is now much drier than I can remember it being and I have the added benefit of sealing up my crawl space entrance which has been the impromptu home for a raccoon or squirrel on more than one occasion. I would definitely recommend this product for anyone facing similar problems as I.
