The Future of Fans is Now

In the fields of commercial and industrial air systems, the success of any setup often comes down to the component at its heart—the fan. Mainstream Fluid & Air introduces a diverse range of BDP Fans, engineered with precision to deliver top-notch performance, efficiency, and reliability. These fans serve not just commercial systems but also a broad range of industrial applications.

Our BDP Fans use the latest in motor technologies. You have the choice between traditional AC motors and our advanced PMEC (Permanent Magnet Synchronous Reluctance) motors. These PMEC motors are on track to revolutionize motor technology, not just in commercial applications, but across various industrial applications as well. When integrated with our BDP Fans, PMEC motors offer a system that’s highly efficient, impressively quiet, and built to last.


One of the standout features of PMEC motors is their ability to deliver consistent performance while keeping energy use low. This balance is critical for today’s HVAC and industrial systems, particularly in an age where energy efficiency is not just nice to have—it’s essential. Combine the energy-efficiency of PMEC motors with the streamlined design of our BDP Fans, and the result is a system that’s both kind to the environment and easy on your budget in the long run.

We at Mainstream understand that both the HVAC and industrial sectors are in the midst of rapid technological changes, many driven by advances in motor technology. Our BDP Fans, powered by PMEC motors, reflect our dedication to staying ahead of this curve. We offer products that meet the needs of today while being well-positioned for the challenges and opportunities of tomorrow.

Our AC motor-driven BDP Fans offer another reliable option, ensuring we meet a variety of needs in both HVAC and industrial settings. These fans provide a tested and trustworthy solution that complements our PMEC motor-driven lineup.
