Replacing an entire fan to achieve performance or efficiency goals can be a costly experience. AirStream specializes in custom impeller upgrades that deliver increased efficiency, performance, and reliability within existing fan housings. Combined with an aim to reuse ancillary equipment, we provide cost-effective solutions to remove bottlenecks, improve efficiency, and extend wear life. Over the years, the success of AirStream’s impeller upgrades inside native housings has become the envy of fan manufacturers across the world.

Our specialized experience gives us the unique ability to guarantee these efficiency and performance improvements over the life of the impeller. To customize upgrade solutions that have the longest wear life and optimized performance, AirStream uses on-site technical inspections and performance testing of existing equipment, iFlow modeling, and proprietary software. Our skilled site services personnel will provide technical assistance during installation to ensure all supplied equipment performs as promised. All housing modifications are custom designed to get the most out of every upgrade.

We don’t believe in the guesswork of a trial-and-error approach. That’s why our rotors are modeled inside native fan housings so that each upgrade is customized and designed for actual site conditions.

Our upgrades achieve the following results:

• Increase fan efficiency and lower electrical costs
• Deliver higher flows to meet increased production requirements
• Reduce wear and maintenance requirements
• Operate in high-temperature environments (up to 500 °C) reducing cooling water and reheat fuel use
• Eliminate hard slate-like build-up on fan components
• Produce predictable results, the first time
