Crawl Space Ventilator

Foundation ventilators also known as crawl space vents play an important part minimizing potential wood decay to your home's foundation caused by excessive moisture intrusion into the crawl space of foundation area.  The unfortunate result of less foundation ventilation has been the increase of wood rot in crawl spaces and moisture problems in the living areas of homes. Moist climates require you to provide and maintain adequately ventilated crawl spaces. A crawl space vent system, in addition to venting moisture vapor, serves to vent out other gases, such as those formed from residues in termite treatment, treated wood, and radon gases. The crawl space vent system protects the structure of the house and the health of its occupants.

To aid natural crawlspace ventilation, mechanical ventilation should exchange the crawlspace air at least four times an hour or once complete air exchange every 15 minutes. To determine this, multiply the square footage of the crawlspace by the height to calculate the cubic feet of the crawlspace and then divide by 15 to determine the CFM needed to properly ventilate your crawl space.

Formula:
Length x width x height = total cubic feet of crawl space
Divide = total cubic feet of crawl space / 15 = CFM needed for proper foundation ventilation.

Example:
40' x 40' x 2' crawl space = 3200 cubic feet of area
divide 3200 cubic feet by 15 =   213 cubic feet per minute (cfm) of air flow needed to ventilate your crawl space

The Crawl Space Ventilator listed below Is Rated At 110 cfm for each unit.  Therefore, 2 units would be required to properly ventilate a crawl space of this size. 
As with all powered exhaust systems, proper intake air vents should be used. Generally, one air intake vent is recommended as a minimum for air intake. Having 3-4 intake vents would be ideal. These crawl space ventilator should be installed on opposite ends of the intake vents, to allow air movement across the entire space to be ventilated.

 

Our powered crawl space vent creates a powered ventilation system for crawlspaces that can be utilized in both old and new construction.  The foundation vent fan is designed to be mounted behind any new or existing crawlspace vent. Its operation is controlled with a temperature switch/humidistat control which activates the motor at or above 50ºF and is user adjustable for the varying levels of relative humidity in your crawlspace.

By incorporating the crawlspace vent into your homes crawlspace ventilation system, you can help stop mold growth, mildew, rot, pest /insect infestation and decrease high humidity levels while increasing the overall airflow within your foundation.
