DeLaval variable speed drive NFO

Cut energy costs by up to 70%. As the name suggests, DeLaval NFO varies the speed of the fans to ensure that they only work as much as necessary. Connected to temperature and humidity sensors, DeLaval NFO will automatically control fan speeds for an optimal barn environment. Not only will this slash power consumption, but it will also extend the lifetime of your fans.
