Virovac is staying on even when cautery not in use. **** just keeps running

The Buffalo Filter ViroVac VV120 continues to run when the cautery is not in use because it does not automatically turn off. It will keep operating until it is manually turned off. Additionally, an Automatic Activation Device can be used to control the suction on/standby modes in conjunction with ESU activation, which helps in saving filter life.
