Abstract
A hose adapter defines a passageway therethrough and has a first connector portion and a second connector portion with the first connector portion being substantially larger in transverse dimension than the second connector portion. A transition portion is disposed between the first and second connector portions. A vacuum device is operatively associated with one of the first and second connector portions, and a hose is secured to the other connecting portion. In one embodiment, the hose adapter has a vent with an associated closure, which is designed to vary the opening in the vent and thereby alter the amount of suction created by the vacuum device. A plurality of interiorly-mounted, inwardly-projecting ribs are provided in the second connector portion to facilitate retention of a hose therein. A vacuum system employing the adapter is disclosed.
