The Evolution of a Revolutionary Duct Cleaning Technology
Evolution of a revolutionary product
Since 1966, our company has been at the forefront of innovation in duct cleaning technology.
What began as a commercial vacuum system has evolved into our proprietary INGRA Vacuum
Technology®—an industrial-grade, high-performance system designed to serve residential,
commercial, and industrial customers across Canada. From food processing plants to senior
living facilities and automotive manufacturing, INGRA delivers unmatched suction power
and cleaning precision.
As one of Canada’s leading duct cleaning companies, we conduct hundreds of system
tests daily, allowing us to continuously refine and optimize our performance. Our current
vacuum technology delivers 50% to 150% more suction power than standard truck-mounted
or portable duct cleaning systems. To put it simply—just like a vacuum with a more powerful
motor cleans deeper, so does our system.
A Legacy of Innovation in Air Duct Cleaning Equipment
Phase 1: The Original Hino Truck System
Our original setup used a Hino truck where the vehicle’s engine powered both the vacuum and
air compressor. While innovative at the time, the engine’s limitations and the truck’s size made it
impractical in dense urban environments.
Phase 2: Cube Van With Side Engine (2010)
In 2010, we introduced a self-contained truck-mounted vacuum system housed in a cube
van. The vacuum and air compressor operated on a separate side engine, making the system
more powerful and flexible—independent from the vehicle carrying it. This was a major leap
toward efficiency and mobility.
Introducing the Latest INGRA Vacuum Technology® (2022)
After five years of research and development, we launched the latest generation of INGRA
Vacuum Technology® in 2022. This system sets a new industry standard for power,
portability, and environmental responsibility.
Key Innovations:
1. Twin-Engine Design
The vacuum and air compressor now operate on separate engines, maximizing
performance and eliminating power-sharing inefficiencies.
2. In-Home Vacuum Deployment
By allowing the vacuum system to be brought directly inside the home, we eliminate up
to 125 feet of suction hose, reducing energy loss and increasing suction power where it
matters most.
3. Dual Power Source: Gas & Electric
This hybrid system reflects our commitment to reducing our carbon footprint, offering
a more sustainable duct cleaning solution for today’s environmentally conscious
homeowners.
4. Industrial-Grade Reliability
Built with premium Honda engines and heavy-duty components, INGRA delivers
maximum durability and performance for demanding industrial and residential jobs alike.
5. Compact, Powerful, and Efficient
Housed in a Ford Transit van, the new INGRA system is smaller and lighter—but more
powerful than previous models. It’s like comparing today’s smartphone to a
supercomputer from the past: compact, efficient, and exponentially more capable.
