Crawling space size is approximately 75 sq ft.** A: I don’t see why it wouldn’t... it has a humidistat to automatically regulate the moisture. It only turns on when needed to suck out the humid air. Just keep in mind that you don’t want another vent or space open to the humid air, or it will just keep the problem going by sucking in moist air... **Q: will this fan work in a basement 800 sq ft X 6' ?** A: I'm not sure about the dimensions but overall the fan works well. **Q: Is fan reversible?** A: do not know if fan is reversible, but I know it never shut off all summer and all of fall ## Frequently Bought Together - Tjernlund V1D UnderAire Crawlspace Ventilator Fan Moisture Mold Reducing, 110 CFM - Tjernlund 950-8304 Underaire Steel Crawl Space Vent, Steel Diamond Pattern, 18" x 10" Screen - Witten Automatic Vent B-EBLACK(MB) "Energy-Saver" Foundation Auto Vent 8" X 16"- Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.lk/products/1149280-tjernlund-v1d-underaire-crawlspace-ventilator-fan-moisture-mold-reducing-110](https://www.desertcart.lk/products/1149280-tjernlund-v1d-underaire-crawlspace-ventilator-fan-moisture-mold-reducing-110) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-09-23*
