Crawl Space Ventilation Fans

Of the wide variety of ventilation fans that are distributed and installed throughout the world, crawl space ventilation fans are perhaps the least common. Few people pay attention to the importance of good ventilation of very small areas of the home, such as crawl spaces. However, if you are looking to turn crawl spaces into storage spaces for clothes or food, then you will find that good ventilation can be very important to keep away mold. Crawl space ventilation fans are quite easy to obtain and they tend to be of the variety that switch on whenever you hit the light switch.

Buying crawl space ventilation fans

Since the total space within a crawl space is quite small, you will likely not have to worry about purchasing a powerful or large fan. A small fan like the type installed in showers or bathrooms should provide enough air exhaustion to keep an average sized crawl space well ventilated. The CFM range that tends to work best for crawl spaces is from 70-110, and these fans tend to be quite inexpensive. You could even choose to install a regular bathroom ventilation fan rather than put in the effort to find fans designed specifically for crawl spaces, but you will need to make sure that the fan can be fitted into the duct system that exists in within the crawl space.

Tips for choosing crawl space ventilation fans

Centrifugal wall space ventilation fans

It is possible to ventilate all of these smaller household areas from a central inline ventilation fan. This fan could provide ventilation through multiple exhaust points and vents located throughout your household, but if your existing vent work is relatively simple then it might cost a lot of money to expand it. However, at the end of the day you could save electricity by ventilating all of these areas from one centrifugal fan.
