The AT-120 from VALET is a top filling disposable filtration CVS power unit with cleaning performance suited for homes up to 6,000 square feet. The AT120's Ametek-Lamb ULTRA flow-thru motor delivers 725 Max AirWatts with a 120 volt dual stage (twin fan) 5.7" diameter motor. Offering low noise operation and hygienic disposable collection, the AT-120 is ready for cleaning homes of every type with exceptional power. The AT120 is part of the Valet disposable bag series central vacuum power units available in three models. The disposable bag series provides exceptional performance by allowing a complete replacement of the filter system every time the bag is changed. The disposable filtration system does not use a secondary cloth filter that impedes airflow, clogs over time or retains odors. Only disposable filtration central vacuums are capable of providing 100% performance with regular maintenance and also provides superior motor protection. The new Valet AT-120 model now includes a longer factory warranty, replacing the older LM-120 model.
