Abstract
A central vacuum unit comprises a cyclonic chamber having a sidewall.

A central vacuum unit comprising a cyclonic chamber having a sidewall, and a motor causing a swirl of air loaded with debris to centrifugally contact an inner surface of the sidewall of said cyclonic chamber, and a lateral outlet defined through said sidewall to provide for lateral discharge of the debris flowing along said sidewall.
A central vacuum unit comprising a motor drawing a first flow of air along a working path, and a fan circulating a second flow of air along a cooling path, wherein the second flow of air is drawn out of the cooling path into the working path by the first flow of air before both the first and second flows be jointly discharged through a common outlet.
