Crawl Space Ventilator
Excessive Amounts Of Moisture Is Bad For Your Home:
Protect your home from moisture. That's right, excessive moisture in your crawl space can destroy your home. Foundation ventilators, also known as crawl space vents play an important part minimizing potential wood decay to your home's foundation. Improperly ventilated crawl space areas can lead to an increase of wood rot, and moisture problems in the living areas of your home. Homes located in humid areas 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.
The Cure For The Problem:
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.
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.
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
Which Tells You How Much CFM You'll Need:
The Crawl Space Ventilator listed below Is Rated At 110 cfm for each unit. Therefore, in our example above, 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.
