M. K. Plastics LeadLag Exhaust Fan Control System

Lance Chen, M.K. Plastics Corporation

M. K. Plastics pioneered the concept and commercial introduction of a laboratory exhaust fan control system, designed, assembled, and factory tested by the fan manufacturer more than ten years ago. The tested and proven, patent pending LeadLag™ system controls the exhaust fan(s) and damper(s) to:

  • Satisfy system pressure, volume, or other system control parameter
  • Control the operation of the redundant or standby fan
  • Optimize system performance
  • Save energy
  • Interact with and report to the BMS

This demonstration will review the available features of our Leadlag system. And we will show an operational system on twin Axijet™ induced flow fans.
