Twin & Tri Lobe Roots Air Blowers for Sewage Waste Tanker Lorries – Sales & Service

Twin and Tri Lobe Roots Air Blowers are the heart of sewage waste tanker lorries, used to create strong vacuum pressure for suction and discharge operations. These positive displacement blowers ensure continuous airflow, stable vacuum levels, and reliable performance in demanding municipal and industrial sewage applications.

In vacuum mode, the blower creates negative pressure inside the tanker, allowing sewage and sludge to be safely sucked from underground septic tanks, soak pits, manholes, and sewer lines. In pressure mode (where applicable), the same blower assists in discharge operations.

S.V. Engineers supplies, installs, services, and repairs sewage tanker blowers for all major brands with assured performance and long service life.

Technical Working Principle

• Operates on positive displacement Roots principle
