Vacuum excavators are versatile machines that can aid in a variety of construction jobsite applications, from safe digging around facilities to spoils removal. However, there are a number of critical components of the trailer and truck-mounted vacuum excavators to keep an eye on to get the most out of your machine.


In addition to daily maintenance check points, such as fluids and filters, the key maintenance points are the blower, water pump, hydraulic system, chassis, grease points and air flow system, according to Ben Schmitt, Westech Vac Systems General Manager.


Craig Svandrlik, West Coast Industrial Sales Manager for RamVac, provided a quick checklist of key items to check:



  • Final filter needs to be free of debris to breathe air through the blower.

  • Check oil on chassis, blower, transfer case and water pump.

  • Inspect cyclones for material and keep them cleaned out.

  • Inspect transition from boom into debris tank and be sure it’s free of rock or other debris.

  • Inspect boom and rear door seals for vacuum leaks due to poor sealing.


Maintain your equipment regularly and service issues as they happen, Svandrlik adds.


Schmitt and Svandrlik sat down and provided a number of tips to help vacuum excavator owners and operators keep their machines running strong.
