Product Description

Why do we need crawl space ventilation fan?

Perennially confined crawl space lacks outside air circulation, causing moist air 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.


Isolation Mesh: Add isolation mesh to prevent reptiles from entering the machine to affect normal operation and stop reptiles from crawling into your living space.

Freeze Protection Thermostat:Built-in dehumidifier & freeze protection thermostat. Dehumidifier control will automatically shut down to protect the machine if the freeze protection thermostat senses outdoor temperatures lower than 35°F/1.7°C.
