In-Line Pneumatic | Quality Assurance Sifters

Easy maintenance- - - - Sanitation - - - -

Our pneumatic sieve compression and modular interlocking frame simplifies your sanitation and maintenance.

  • Sifter can be opened, sieves completely removed and maintained, and reassembled in minutes... without special tools. Downtime is minimized.
  • Pneumatic sieve clamping system allows fast disassembly. The sieves and screen trays simply
    interlock with one another.
  • Using pneumatics the upper drive frame is raised to open the sifter or lowered to compress and seal
    the sieve stack. The pneumatics maintains constant compression while the machine is in operation.
  • Our drive and frame carriers are engineered to minimize gasket wear and eliminate leaks.
  • Stainless steel sieve and product contact zone construction allows cleaning to be accomplished with dry brushing, air cleaning, water wash down or steam cleaning.
  • Dust tight gasketed construction. No suction requirements.
  • Sieves remove completely. Smooth crack and crevice free bottom dome with easy access to outlet transitions for thorough cleaning.
  • Upper and lower drive carriers remain attached to the drive mechanism.
