Introduction

Northstar Vacuum Disc Filters (R) LogoThe Northstar Vacuum Disc Filter, manufactured by Superior Industrial Products, Inc., has proven to be the most efficient unit on the market today.

OPTIMUM EFFICIENCY IS ATTAINED BY

  • Comparing filter areas and size of filtrate tubes to get the optimum ratio
  • Incorporating a chain drive in lieu of the standard worm drive, thus lowering maintenance costs
  • Lowering the velocity in the filtrate tubes to keep the wear to a minimum
  • Decreasing vacuum requirements, thus decreasing operation costs
  • Using external staggered tubes to allow easy access when maintenance is necessary Northstar Vacuum Disc Filters can out-produce the competition by a significant margin while achieving the same moisture percentage
  • Or...  Northstar Vacuum Disc Filters can achieve a lower moisture percentage than the competition while achieving the same production rate.
