AlorAir 720 CFM Crawl Space Ventilation Fan

The VentirPro 720 utilizes a 10-inch aerofoil fan, producing a flow of 720 CFM, to deliver highly efficient ventilation and cover areas up to 7400 cubic feet. It aids in regulating temperature and humidity levels in your space, ensuring a safe and comfortable environment, making it perfect for use in basements, attics, garages, and any area requiring improved air circulation.

Why do we need a crawl space ventilation fan?

Perpetually enclosed crawl spaces often lack proper outdoor air circulation, leading to the accumulation of humid air. Over time, this moisture buildup can foster mold growth and cause wooden structures to decay, compromising their structural integrity. Additionally, damp wood attracts pests like insects and rodents, which further damage the structure through chewing and erosion.

Moreover, mold spores can become airborne and infiltrate living spaces through floors, crevices, and HVAC systems located in the crawl space. This contamination results in indoor air pollution, posing health risks to occupants.
