The Northstar Vacuum Disc Filter®

Table of Contents

Introduction

The 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…  the Northstar Vacuum Disc Filter® can achieve a lower moisture percentage than the competition while achieving the same production rate.
