Vornado creates cutting edge products - so when we set out to create a window fan, we did our research and then rewrote the formula. The result was just over 6" tall, unobtrusive and clever enough to be seamlessly installed in windows from 24” up to 38" wide using an innovative modular block system. Its electronically reversible chamber smoothly brings fresh air in or exhausts stale air out. Rain or shine, the weather-resistant casing doesn’t mind. Either way, you’ll still enjoy the view.

My son really loves it the best window fan money can buy. Antwuan. Syracuse, NY. Sat Aug 15 2026

The automatic louver vent opener was designed to automatically control the temperature and provide additional ventilation in all Canopia greenhouses. As the air inside the greenhouse warms, the vent gradually opens to allow the correct amount of air flow into the greenhouse and closes when the optimal temperature is reached. The vent arm was designed with the use of natural minerals that expand with heat to push a piston, which raises the window, as the air gets warmer then contracts as it cools, closing with the use of a spring. The automatic vent opener operates without the use of electricity.

Perfectly manufactured and instructions easy. Tom. Las Vegas, NV. Fri Jul 17 2026

The RSI general purpose greenhouse & small building electric powered exhaust fan system is designed to fit all structures. The general design is for low profile structures that are in need of air. Their fan is proudly made in the United States and truly designed to fit all structures, but the purchaser needs to be able to retrofit the exhaust system to their own structure since each structure and building materials are different. Two ways fan can be mounted, from the outside or from the inside. If mounting from the outside a hole in the wall would need to be cut to allow for the fan and interior cage to fit through the wall. Use fasteners (not included) to fasten the fan to the wall by drilling through the framework and caulking the framework to make it water tight. The fan structure is now 100% enclosed in the building and the louvers are on the outside of the structure. If mounting from the inside, a hole in the wall would need to be cut so that the louvers will be able to open and close freely. Slide it in the opening from the inside out. The exterior lip around the louvers acts to finish off the appearance from the outside. Seal with caulking and fasten the fan to the wall (fasteners not included).
