The powerful, flo-thru motor is manufactured by Ametek-Lamb, the folks that have been putting motors in the very best central vacuum systems for years.

Whatever your home layout, whether multi-level, two-story or ranch, a Central Cleaning System can be planned to meet your needs. As few as two or three inlets can take care of an average size home. We recommend one inlet for every 700 square feet of living space. In new homes under construction, installation is simple! Just plan the location of the Power Unit and Automatic Inlets with your builder or contractor. Tubing and Inlets are installed and electrical hook-up for the Power Unit is made before drywall, plaster or finished flooring is in place. That&#039;s all. For those trying to stretch their home building dollars, a home can be conveniently pre-tubed, with the power unit selected and installed at a later date. Installation is also easy in existing homes. Cutting through drywall, plaster or flooring can be kept to a minimum and is determined by the number and location of the Inlets. Tubing can be run through cold air returns, closets and stairwells. Inlet Kits can be purchased that come complete with installation instructions.included. A typical installation can usually be accomplished in a day or less.
