When walking around a Vac2Go vacuum truck, you will see a variety of different components, all performing their own specific function that allows the vacuum truck to properly operate. Among all of these components is the blower. The blower, more or less, is the heart of the vacuum system.
Located on the blower is an intake side as well as a discharge side. When the blower is operating, large volumes of air are displaced from the intake side to the discharge side. This creates air flow and allows material to be conveyed through the suction hose. The blower is designed to enable to vacuum truck to vacuum solids from beneath water surfaces and to convey material for distances of over 600 feet under the right conditions. The amount of airflow created by the vacuum pump is controlled by the engine speed with maximum vacuum limited by the relief valves and airflow. The level of vacuum can be monitored on the vacuum gauge located on the master control panel.
To initiate the blower, the vacuum truck must be started and idling and the power of the truck must be diverted from “Road Mode” to “Blower Mode”. When this occurs, you will hear the blower “engaging” and the drive shaft will begin to rotate. The blower is driven by the chassis engine through a heavy duty transfer case. Once the blower is engaged, air begins to flow through the blower. Clean all will flow from the microstrainer and enter the blower through the blower inlet or intake side.
The higher vacuum systems also have an air injetion system to provide additional air flow to cool the blower during operation.
**Note: The driveshaft is extremely dangerous when rotating and can cause injury or even death. Once the blower is engaged, keep a safe distance from the driveshaft and also keep any tools or objects a safe distance away. Never go underneath the vehicle with the engine running. Never work near a rotating drive shaft. Never attempt to engage or disengage the pump or any driven equipment from underneath the vehicle with the engine running.
