Find the right high-velocity system for your home at F.W. Webb. A high-velocity system uses flexible and small ducts to provide cool air quickly and efficiently to a home that can't support a traditional central air conditioning unit. This air moves four times faster than the speed of a conventional system. Since this system doesn't need large metal ducts, it's an ideal choice for an older home with less space. Use our convenient filters to sort high-velocity air handlers by size, material, end connection, bend angle, and capacity. Browse top-quality high-velocity systems from trusted maker Spacepak to find the best fit for your residence.
