  • Reduces the recovery time when overhead doors are open via a constant flow of air throughout the space
  • Eliminates the need for noisy "man-cooler" type fans throughout the facility
  • Will not interfere or disrupt make-up air, heating or air conditioning systems
  • Variable frequency drive provides soft start and full variable speed operation
  • Control of fans operated manually, automatically or via building management systems
  • Emergency shutdown feature on control to interlock with the building fire alarm panel
