Crawl Space Fan 110 cfm Plug-in

The Tjernlund crawl space fan is an automatic plug-in unit designed to ventilate confined foundation areas. Its galvanized steel housing and steel frame resist corrosion in damp environments. A built-in thermostat and dehumidistat control operation based on temperature and humidity levels.

Homeowners managing moisture in accessible crawl

This fan suits owners who need continuous, sensor-driven airflow without wiring a dedicated circuit. The plug-in design connects to a standard outlet for immediate use. Builders requiring ducted distribution to multiple zones or higher static pressure should consider alternative ventilation systems.

Maximum airflow 110 cfm

The unit moves 110 cubic feet of air per minute at open discharge. This single figure determines whether the fan can meet the ventilation rate calculated for a specific crawl space volume. Verify the required air changes per hour against this capacity before purchase.
