The supply air inducer is attached to supply side of the ductwork and will introduce a small amount of conditioned air into the crawl space to help regulate the RH. It includes a backflow damper to keep bad air from entering the system.
50 cfm (where building code requires 1 cfm per 30 sq. ft., this unit will cover up to 1,500 sq. ft.)

Just started using this product and it has been great. Easy to install and works great!

After sealing off my crawlspace I installed one of these in my supply ductwork to help with humidity control. I has been working fine now for over two years, keeping the relative humidity below 55%. The only issue is that when my HVAC system isn't operating, such as in the Spring & Fall, I get no humidity control in the crawlspace and small amounts of mold are returning on the floor joists. My crawlspace is approximately 2500 cubic feet. I've decided to install a dehumidifier in addition to the inducer.

This would have to be our favorite method of conditioning a crawlspace. We use them on many homes here in central Indiana. The backflow damper works as described to prevent the unwanted crawlspace air from re-entering the crawlspace. Our company <a href="http://www.indianacrawlspacerepair.com/free-estimate/">Indiana Crawl Space Repair</a> strongly recommends them to any and all crawl space contractors.
