Eurovac drops have either a single or double inlet. The inlets for Eurovac I and Eurovac II 5HP and 10HP systems usually have a microswitch or toggle switch which turns on the vacuum system when the inlet flapper valve is opened. Eurovac III and larger systems are usually continuous run systems because frequent starting and stopping of the larger motors uses a lot of extra electricity, and it is very hard on the electronic components. Each drop includes a hose hanger and tool hanger.
