The H2 vacuum truck, specifically referring to Hypervac Technologies' H2 Duct Truck, is a specialized vehicle designed for air duct cleaning. It's a smaller, more maneuverable version of the H1 model, built to fit on modern chassis like the Ford Transit, Dodge ProMaster, and Mercedes Sprinter. The H2 is known for its fuel efficiency, reduced wear and tear on the chassis, and ability to access tighter spaces. 

Here's a more detailed breakdown:

Key Features and Design:

• Smaller Size:

  The H2 is 6 inches narrower and 6 inches shorter than the H1, making it easier to navigate narrow streets and driveways in older neighborhoods and cities. 

• Chassis Options:

  It can be mounted on a variety of chassis, including the Dodge ProMaster, Ford Transit, and Mercedes Sprinter, which are often more fuel-efficient and easier to maneuver than traditional truck chassis. 

• HAVAC Vacuum System:

  The H2 utilizes a unique HAVAC vacuum system with a 35 HP Briggs gas engine and direct drive (no belts) for powerful and efficient suction. 

• No More PTO:

  The design eliminates the need for a Power Take-Off (PTO), reducing maintenance and potential breakdowns. 

• Improved Cleanout System:

  A single, large cleanout bin simplifies debris removal, eliminating the need to access the roof to empty the bag. 

• Integrated Compressor:

  The H2 includes a powerful compressor (43 CFM at 175 PSI) for various applications, including dryer vent cleaning. 

• Large Hose Capacity:

  The hose bay is designed to hold a significant amount of vacuum hose, typically 175-200 feet. 

• Lightweight Construction:

  The truck's design prioritizes weight reduction to minimize fuel consumption and wear on the chassis. 

• Ladder-Free Operation:

  The design allows for easy access to the bag and cleanout system, eliminating the need for a roof-mounted ladder. 

Benefits for Duct Cleaning Professionals:

• Fuel Savings:

  The H2's efficient design and lighter weight contribute to reduced fuel consumption. 

• Reduced Maintenance:

  The elimination of the PTO and the use of a simpler engine design reduce maintenance needs. 

• Accessibility:

  The smaller size and maneuverability allow access to a wider range of locations. 

• Efficiency:

  The powerful vacuum and efficient cleanout system contribute to faster and more thorough cleaning. 

• Cost-Effectiveness:

  The H2 can be more affordable to purchase and operate compared to larger, heavier duct cleaning trucks. 

In essence, the H2 vacuum truck is a purpose-built, modern solution for air duct cleaning, designed to address the needs of professionals with a focus on efficiency, maneuverability, and reduced operational costs
