Coolerguys is proud to launch our IP67 dust and waterproof fan series. These IP67 fans can be submerged up a meter underwater for up to 30 minutes. At 201 cubic feet per minute of airflow, these are perfect for systems exposed to the elements that need a lot of airflow such as sheds, RVs, yachts, pest control, and exterior AV systems. Will work with solar panels as small as 10w. Please note that while the fan is waterproof, the power supply and its connectors are not so please keep those enclosed.
