Instructions for Changing the plastic can liner.
AstroVac central vacuum systems feature either a specially designed micro lined paper bag, or inverted cyclonic filtration to capture debris. The paper bag unit has a unique baffle system, which maximizes the useful filter area of the bag, providing large dirt capacity and maximum performance. The inverted bag is a permanent filter, requiring only occasional cleaning. The debris is collected in a dirt canister, which is an integral part of the power unit.
