Vacuum Excavation

Hydro excavation equipment, including vac trucks and vacuum trailers for high-suction pumping applications, must comply with many local and state regulations. One such regulation requires hydrovac systems to stay below specific noise levels during certain hours of the day. Dürr Universal has extensive experience designing and manufacturing standard and custom blower silencers to help vacuum excavators meet these noise limits in residential areas.

Noise control solutions for mobile vacuum pump/blower applications

Whether customers use small, trailer-mounted vacuum pump/blower systems or large, truck-mounted vacuum pump/blower systems, Dürr Universal has the solutions to quiet the noise to acceptable levels. Customers in the portable restroom, utility daylighting and sewer-line-cleaning industries trust Dürr Universal’s vacuum excavation blower silencers.
