Custom SystemsThese are the premier BaseVac™ central vacuum systems. The industry leading engineers at BaseVac™ will design the system specifically to your needs. From rooftop installations to huge multi operatory clinics they have the solution to whatever unique situation you have. These systems are available as duplex and triplex systems, with additional capacity upon request. Except for the latter, all are expandable, using standard factory modules, up to a triplex. As with the tank mounted units, all come with the basic accessories; mounting, however, is vertical. Each pump is mounted on its own stand, which stacks, one above the other. Each pump is connected to a central manifold, which is plumbed to a vertical air water separator.
