PMEC Fan Arrays

The Future of Ventilation

Want to know why Mainstream is on the cutting edge of EC fan technology?

Remember these four letters: PMEC.

Also known as Synchronous Reluctance EC technology, these next-generation fans use permanent magnets to achieve full load and partial load efficiencies that surpass what was previously possible.

PMEC fans are:
  • More efficient than EC and AC
  • Easily accessible as they do not use rare earth materials
This translates to…
  • Energy savings costs
  • Faster shipping time since the product is less susceptible to supply chain disruptions

Mainstream is already utilizing PMEC fans in our arrays and fan sections. We also offer mounted PMEC fan solutions for OEM AHU manufacturers and industrial applications.

If you’re moving air, we can help you do it better.
