Vacuflo FC650 is the perfect choice for homes up to 8000 square feet. VACUFLO Filtered Cyclonic power units feature Cyclonic Filtration Technology® (CFT™), a unique dual filtration process that utilizes cyclonic separation for primary filtration and a pleated filter for secondary filtration. Unlike central vacuum systems that rely on permanent cloth filters, the powerful performance of VACUFLO will not decrease as dirt accumulates. CFT creates a powerful centrifugal force that separates the dirt and debris from the airflow. As the dirt spins around, the air pressure forces it through a cyclonic cone and deposits 96-98% of all the vacuumed dirt into an easy-to-empty canister located away from the living area. The remaining 2-4% of fine dust particles are trapped in the high-performance pleated filter. With VACUFLO Filtered Cyclonic, there is no chance for dust or vacuum odors to recirculate into your living area. The result is a cleaner, fresher and healthier home. See less
