Fantech Crawlspace Fans

Having a crawlspace fan depends on the needs of the crawlspace. However, it is always good to find ways to prevent moisture building up. If you believe that it is necessary to have one, calculate the number of crawlspace fans you will need. This is done by finding the length and width of the crawlspace. Once you find this, you can multiply the length and width together to see how many you need. A general standard is to use one exhaust fan and one intake fan for every 2,000 square feet. Find the number of crawlspae fans using the following formula:

• Length of Crawlspace (Sq.ft) x Width of Crawlspace (Sq.ft) / 2000 Sq.ft

Find the length and width of the crawlspace. Once you find this, multiply the length and width together to see how many you need. A general standard is to use one exhaust fan and one intake fan for every 2,000 square feet.

Crawlspace fans that are primarily installed on outside walls of your crawlspace, position them far away from your dehumidifier. You should install crawlspace fans at least 3 feet away from any outside corners behind existing crawlspace vent openings. Ensure you are taking precise measurements of the vent dimensions so you can purchase the correct sized fan.
