Vacuum truck performance depends on more than airflow and vacuum ratings. The engineering inside the blower influences how efficiently it operates, how much maintenance it requires, and how reliably it performs under demanding field conditions.
The Hibon VTB820.XL was developed specifically for the vacuum truck industry, combining a three-lobe positive displacement design with Hibon’s air injection technology to improve efficiency while supporting high-vacuum operation.

One of the defining features of the VTB820.XL is its integrated air injection system. Unlike conventional blower designs, air injection introduces a controlled amount of ambient air into the compression process. This helps manage internal temperatures while allowing the blower to operate efficiently at high vacuum levels without relying on a water cooling system. For operators, this means dependable performance during demanding operating conditions while simplifying the overall blower system.
The VTB820.XL utilizes a precision-engineered three-lobe impeller design.
Compared with traditional two-lobe designs, three-lobe technology helps deliver smoother airflow while supporting improved operating characteristics in demanding vacuum truck applications.
Combined with Hibon’s air injection system, the three-lobe design contributes to:
Rather than focusing on a single performance specification, these design features work together to improve overall blower performance.
The VTB820.XL was engineered specifically for the demanding requirements of modern vacuum trucks.
Its design makes it well suited for applications including:
Every application places different demands on the blower, but the goal remains the same: dependable performance throughout long operating days.

Several engineering features distinguish the VTB820.XL from conventional blower designs.
The blower incorporates automatically adjusted rotor clearances during assembly, a large oil capacity, high-volume oil throwers, and a piston-ring sealing arrangement designed to support long-term operation.
Combined with air injection technology, these features contribute to cooler operation, improved bearing lubrication, and reduced maintenance requirements over the life of the blower.
Every engineering decision ultimately affects the people operating the equipment.
For fleet managers, reliability means more uptime and predictable maintenance.
For OEMs, multiple mounting configurations provide installation flexibility across different truck designs.
For operators, oil-free air, simplified maintenance, and dependable performance contribute to greater confidence on the job.
No two truck builds are exactly alike.
To simplify integration into a wide variety of vacuum truck designs, the VTB820.XL is available in multiple shaft orientations and rotation configurations.
This flexibility allows OEMs to optimize installation while maintaining the blower performance expected from Hibon.
Air injection helps manage operating temperatures while supporting high-vacuum performance without requiring water cooling.
