Exactly what I need

High-tech, high setting, suitable for general basement ventilation. I made custom wooden window panels to install two units in the basement windows. Even when smoking, with these dual fans, all the smoke can be ventilated outdoors without the smell of smoke upstairs! They minimize the impact of cigars on the family and the cigar house itself. Living in Minnesota is not a viable option for smoking outside! Love them!
Elaborate crawl space fan

I need a fan for small crawl space under a building that has a hidden air leak for several months. To install the dehumidifier, I will have to crawl about 60 feet in the mud. This product is very suitable for the ventilation holes of standard buildings and has a foam seal to prevent air leakage from around the equipment. It contains a built-in switch that will automatically turn off the fan once the desired humidity level is reached. It is made of sturdy stainless steel and has two sturdy fans.
Humidity insurance

I have a new long and narrow house with crawl space. This kind of foundation has a greater risk of damage from moisture (including mold) than a slab or basement foundation. I installed two of the fans in the crawl vents as a relatively inexpensive form of high humidity protection. The DC motors in these fans have significant design advantages, and the fans are indeed very quiet. Besides, the system reduces the humidity level to prevent the growth of mold while expelling odors and other harmful pollutants from the home.
