Ventilation Fans

Crawl Space Fan

What It Does:

Venting a crawl space with outside air is a bad idea. When you vent your crawl space using outside air you are bringing cold winter air and summer humidity into your home. These lead to damaging mold and rot underneath your home.

The Crawl-O-Sphere™ Crawl Space Fan provides another way to ventilate a crawl space environment without the use of unconditioned air. This crawl space ventilation system uses the already-conditioned air present in your home. The Crawl-O-Sphere™ is for use only in homes with central air conditioning.

The Crawl-O-Sphere™ is intended as part of our crawl space vapor barrier system. When combined with our crawl space moisture barrier and vent covers, it provides a cost-effective way to keep a crawl space dry.

Installation Time:

Mounting a Crawl-O-Sphere™ in between the floor joists and installing a vent to the floor above will be done within the specified time frame for the rest of the job.

Properly Ventilating A Crawl Space

There are many products on the market these days that are used to ventilate crawl spaces. Which one is best? Some suggest taking air inside your crawl space and blowing it out of the house. Others recommend blowing air from the outside into your home. But what if it's damp, humid, or cold outside?

At Crawl Space Solutions of Arkansas, we recommend installing a crawl space dehumidifier over using a crawl space fan. However, if you're looking for a more economical way to dry your space, the Crawl-O-Sphere™ is the way to go.

Since an encapsulated crawl space becomes part of your housing envelope, you can dry it without significant changes in your home's energy efficiency. Depending on the size of your crawl space, this system will typically draw between 15 and 80 cubic feet of air per minute from the home above.
