Get an instant upgrade when you modernize your wastewater system with a VanAire retrofit
We can improve on any competitor’s system.
While VanAire is known for designing and manufacturing some of the most durable wastewater systems in the world, we are also experts at improving existing underperforming systems through our retrofit service. By applying decades of experience, we upgrade existing equipment to deliver stronger performance, greater reliability, and improved efficiency.
A VanAire retrofit replaces the underperforming components of your system with state-of-the-art technology. The result is increased output, reduced maintenance costs, and the exceptional reliability of the superior MicroAire DAF® technology that VanAire is known for.



Our technologically advanced equipment dramatically improves wastewater system efficiency, effluent clarity, and by-product recovery, while also enhancing water quality and overall system operation. Reductions in chemical usage can often generate a return on investment in months.
Here’s how it works:
We begin with an initial remote consultation to discuss your challenges and explore potential solutions. Afterward, a member of our team will visit your facility to evaluate your system in person and finalize our recommendations.
Once the plan is approved, we assemble and manufacture the required components and deliver them to your facility. The VanAire team will then install and configure your custom retrofit, helping your system perform better than ever before.
Upgrade options include:

Floated solids skimmer system
We have dozens of skimmer systems that have been effectively skimming solids for decades with only minor maintenance.

Microaire DAF Aeration
The MicroAire DAF Aeration Unit, combined with our proprietary breakout valve, backed by over 30 years of R&D, precisely controls and delivers highly effective bubbles for wastewater clarification and byproduct recovery.
