Advantages:
1. Reduce the moisture in the crawl space/foundation and protect the family and passengers.
2. Increase air circulation to prevent condensation and wood rot.
3. Raton gas at the exhaust port, treated wood gas and peculiar smell, prevent moving to the living area. 4. Automatically turn on/off to set the humidity% level.
5. Replace outdoor and indoor air, improve indoor air quality, and balance humidity. This helps to reduce the radar level in the crawl space, because the radar (density) is heavier than the air, so it will settle on the lower floor.
The 100% stainless steel 430-grade panel and shell can extend the service life in humid environments. (Better than other brands of galvanized steel.)
