Origins and Development of the Paragon System
Paragon pre-cleaners were born out of a need to address persistent engine air filtration problems in heavy equipment operating under extreme conditions. Developed by Knaus Air Solutions, the system underwent thousands of hours of prototyping and field testing before reaching commercial release. The goal was to create a pre-cleaner that could outperform traditional centrifugal and ejective systems while reducing airflow restriction and maintenance costs.
Unlike conventional pre-cleaners that rely on bottom-up airflow or passive separation, Paragon units use a patent-pending design that maximizes particulate ejection efficiency while maintaining high airflow volume. The result is a system that removes finer dust, snow, and debris before it reaches the primary air filter—extending filter life and improving fuel economy.
Design Features and Technical Advantages
Paragon pre-cleaners incorporate several innovations:
Performance in Harsh Conditions
Operators in northern climates often struggle with snow-clogged filters, requiring frequent stops to replace or clean elements. Paragon pre-cleaners have proven effective in preventing snow buildup, allowing machines to run uninterrupted during blizzards and freeze-thaw cycles.
In one case from Saskatchewan, a road maintenance crew equipped their graders with Paragon units during a record snow season. Filter replacements dropped from twice daily to once every two weeks, saving labor and reducing downtime. Fuel consumption also improved by 4%, attributed to reduced intake restriction and cleaner combustion.
Economic Impact and Maintenance Savings
The financial benefits of Paragon pre-cleaners are substantial:
Industry Adoption and Market Feedback
While the product has gained traction among independent contractors and municipal fleets, some users have raised concerns about pricing. At nearly $1,500 per unit, Paragon pre-cleaners are significantly more expensive than traditional options like the Turbo III or Sy-Klone Series 9000. However, supporters argue that the long-term savings and performance gains justify the upfront cost.
Manufacturers have yet to universally approve Paragon units for warranty coverage, prompting some operators to seek written exemptions or install the units post-warranty. Despite this, adoption continues to grow, especially in regions with severe environmental challenges.
Installation Tips and Compatibility Notes
To ensure optimal performance:
Field Anecdote and Practical Insight
In Shanghai, a mining operator installed Paragon pre-cleaners on a fleet of aging Komatsu WA470 loaders. Previously, filters clogged every 8 hours due to fine silica dust. After the upgrade, filter life extended to 40 hours, and engine wear indicators dropped by 30%. The company later standardized Paragon units across its entire fleet, citing reduced maintenance costs and improved operator morale.
Conclusion
Paragon pre-cleaners represent a leap forward in engine protection for heavy equipment. By combining advanced airflow design with high-efficiency particulate separation, they offer a compelling solution for operators battling dust, snow, and debris. While the price may deter some buyers, the long-term benefits in fuel savings, filter longevity, and reduced downtime make them a strategic investment for demanding applications. As environmental conditions grow harsher and equipment uptime becomes more critical, innovations like Paragon will continue to redefine what’s possible in air filtration.

Design Features and Technical Advantages
Paragon pre-cleaners incorporate several innovations:
- Top-down airflow architecture: Dirty air enters from the top, allowing gravity and centrifugal force to expel contaminants downward and outward.
- Low restriction housing: Engineered to minimize pressure drop across the intake system, preserving engine performance.
- High-efficiency separation chamber: Captures both large and fine particulates without recycling expelled dust.
- Quick installation: Most units can be mounted in under five minutes, with universal fitment options for various intake diameters.

Economic Impact and Maintenance Savings
The financial benefits of Paragon pre-cleaners are substantial:
- Fewer filter replacements: Extending filter life by 3–5x reduces inventory and labor costs.
- Lower fuel usage: Improved airflow leads to more efficient combustion and reduced engine strain.
- Less downtime: Machines stay in the field longer, improving productivity and job completion rates.

Installation Tips and Compatibility Notes
To ensure optimal performance:
- Match the pre-cleaner size to the engine’s airflow requirements (CFM)
- Use proper intake adapters and clamps to prevent leaks
- Position the unit to avoid obstruction from cab structures or loader arms
- Inspect the ejection ports regularly for blockage or ice buildup
