Allegro Vacuums MU4101 Central Vacuum Other sku-5568451787

Allegro Vacuums MU4101 is an Other-color central vacuum power unit listed under Vacuums, Steamers & Floor Care (SKU sku-5568451787; UPC 744702137496). Made in Canada since 1997, its steel housing is intended for spaces up to 3,000 sq. ft. Performance specifications are 550 air watts, 125 inch water lift, 121.0 CFM and 13.8 Amp.

The single-speed, 2-stage 5.7 inch Ametek Lamb blower motor has tangential bypass, a 10 mm shaft and bearing system, and a separate fresh-air cooling fan. It directs heated or dirty exhaust out of the motor chamber. The hybrid unit works with or without bags.

Its HEPA system captures up to 99.97% of allergens; a permanent self-cleaning filter captures microscopic particles without removal or washing. Allegro's triple-layer bags filter fine dust and allergens while helping maintain airflow and suction. The unit has a lifetime warranty against corrosion perforation and a 7-Year manufacturer's motor warranty.

According to the product information, thru-flow motors are generally used in portable vacuums and are unsuitable for central vacuum use: they lack a separate cooling fan, expose motor and electrical parts to vacuumed air, can make carbon brushes difficult or impossible to replace, and tend to run at higher RPM, shortening service life.
