The 5.5mm isolation mesh prevents reptiles from entering, ensuring a secure and clean airflow. The high weather-proof feature makes it ideal for humid environments, offering a long service life with no maintenance required.

Installation & Operation: Designed for easy installation and operation, the fan has a compact size of 16" x 4.1" x 11.1" and a 10-inch fan with a 6-foot grounded power cord. The faceplate can be trimmed to fit different installation needs. A simple knob control panel makes it easy to set the humidity level for optimal fan operation. Just plug in, set the desired humidity, and let it run continuously to vent radon gas, treated wood gases, and unpleasant odors, preventing them from entering the living space.

Protection: The constant operation of the fan helps prevent condensation and wood rot in damp areas, ensuring continual protection for your crawl space and basement. With its pre-installed factory thermostats, the fan will not operate if outdoor temperatures fall below 35°F, ensuring energy efficiency and safety.
