The ATQ-300 from VALET is a top filling disposable filtration CVS power unit with cleaning performance suited for homes up to 10,000 square feet. The ATQ300's Ametek-Lamb PREMIER bypass motor delivers 631 Max AirWatts with a 120 volt dual stage (twin fan) 7.2" diameter motor. Offering the lowest noise operation and hygienic disposable collection, the AT-300 is ready for cleaning homes of every design and size with exceptional power. The ATQ300 is part of the Valet disposable bag series central vacuum power units available in three models. The disposable bag series provides strong cleaning performance by allowing a complete replacement of the filter system every time the disposable bag is changed. The disposable filtration system does not use a secondary cloth filter like bagless vacuums. Only disposable filtration central vacuums are capable of providing 100% performance with regular maintenance and also provides superior motor protection. The new Valet AT-300 model now includes a longer factory warranty, replacing the older LM-300 model.
