Product Description
room to room ventilation fan

Why do we need a crawl space ventilation fan?
Perennially confined crawl space lacks outside air circulation, causing moist air to collect in the space. Prolonged moisture causes to grow and wood to rot, which affects the structural integrity of the wood. Wet wood also attracts annoying groups like reptiles that gnaw and erode, causing additional damage to the wood. What's more, airborne spores enter your living space through floors and cracks and even crawl space HVACs, thus creating indoor air pollution that will endanger you and your family's health.

Our Alorair 540CFM crawl space ventilation fans, available in sizes ranging from 3600-5600 cubic feet, can solve your problem
