Unlike most central vacuum systems which use bags and/or filters to remove dirt from the air, the Galaxie GA-100 uses neither a bag nor a filter. The GA-100 operates on a special principle which separates dirt and deposits it into a large easily emptied dirt container. This sytem allows the vacuum power to remain constant since the air is unrestricted by the fabric of bags or filters, both of which can increasingly restrict air flow when they become clogged with dirt as the air is forced through them.
