Envanio Universal engineers compact, lightweight silencers that dramatically reduce blower noise without creating restrictive backpressure that limits excavating power. Supported by extensive engineering expertise, our solutions help operators of hydro excavation equipment overcome technical, regulatory, and economic challenges in achieving effective noise attenuation safely, efficiently, and sustainably. ### Strict Urban Noise Ordinances Vacuum trucks operating in urban areas must comply with stringent municipal noise limits to avoid job-site disruptions, penalties, and regulatory violations. ### Space & Weight Constraints Limited truck chassis space and payload restrictions require compact, lightweight silencer designs that maximize performance without compromising vehicle capacity. ### Abrasive Debris Carryover Soil, slurry, dust, and other abrasive contaminants carried within the airflow can accelerate wear on high-vacuum blower lobes, reducing equipment life and reliability. ### Backpressure Penalties Excessive airflow restriction can increase system backpressure, reducing vacuum performance, limiting operational efficiency, and driving higher fuel consumption. ### Severe Vibration & Thermal Cycling Vacuum truck systems must withstand severe vibration, road shock, and rapid thermal cycling caused by heavy-duty operation and abrupt load changes, ensuring long-term durability and performance. Key Applications Requiring Noise Control ------------------------------------------ ###### Sewer Jetter ###### VAC Trucks ###### Vacuum Trailers/Excavators ###### Portable Restrooms ###### Utility Daylighting Suitable Solutions for Hydro Excavation Equipment --------------------------------------------------- Noise control requirements vary based on your operating environment, equipment configuration, as well as local regulatory standards. Envanio Universal offers both standardized and custom-engineered solutions designed to meet your specific operational needs, drawing from a broad portfolio of field-proven technologies.
