75 GPM Pro+ Big Dipper W-750-AST


How A Grease Trap Works

The Big Dipper automatic grease removal device lets you take control of grease and small food particles in an easier and more hygienic way. Its electrical assembly includes a heater, skimming wheel and skim setting controls that work together to remove grease from the tank and store it in a separate grease collector.

With the NEW Advanced Maintenance Assistant option, the W-750-AST also automatically empties small food particles from its basket filter and pushes these particles downstream. Taking just 1 minute a day to empty the grease collector limits exposure to food waste, grease and fats while eliminating pumping fees.

  • Hygienic solution with minimal exposure to grease and small food particles
  • Proprietary pump automatically jettisons small food particles down the line
  • Advanced odor protection keeps odor inside the tank
  • Minimal maintenance is ideal for remote locations where servicing can be difficult
  • Fully automatic self cleaning cycle. Removes collected grease & oils from tank without any operator assistance. Comes complete with digital control interface and Grease Collector.
  • Constructed of corrosion resistant materials suitable for installation in virtually any location. Attractive sanitary Stainless Steel exterior.
  • Integrated Motor/Grease Outlet/Heater/Lid enables a fast, do-it-yourself unit operation reversal.
  • Compact footprint.
  • Two (2) No-Hub Connectors provided.
