What the heck is a Fan Combination unit?

Vac2Go Operation

When renting a vacuum truck and before beginning any municipality or other work which would require a combination unit vacuum truck, it’s important to understand the work you will be doing so you know which type of combo unit is right for you. Below are the features of a “Fan” combination unit vacuum truck.

On the front of the vacuum truck, there is a hose reel with the operating controls located at the front and back of the reel. On top of the vacuum truck you will find the boom assembly as well as storage racks with additional aluminum tube sections to give you better access to debris in the manhole or catch basin. The boom enters the forward bulkhead of the debris body where debris is knocked out of the airstream and onto the floor. The airstream is further filtered by optional cyclone filters mounted to the rear of the debris body. After leaving the cyclone tubes the airstream is directed towards the fan assemblies, which are either single or dual stage fans. The fans are driven by an auxiliary engine. Mounted beneath the auxiliary engine radiator there is a tool box for the filter strainer, jetting nozzles, and pendant storage as well as the rocker switches for the debris body and rear door functions. Water tanks are mounted on both sides of the vacuum truck for equal water distribution. On the right side, in place of an additional water tank, there is a rodder pump behind the tube and two additional storage racks on both sides of the debris tank for additional tubes to ensure complete and efficient job setup and completion.
