Dense Phase Pneumatic Conveying

CONTINUOUS Dense Phase BY Haf Equipment

Haf dense phase
Models for Food Grade, USDA, Chemicals, Plastics and Nutraceuticals
CDP technology uses a vacuum-throttling valve, positioned at the intake of the blower. This, in conjunction with control software, accurately maintains the material-air mass flow ratios at constant levels, resulting in stable, low velocity, continuous dense phase conveying.
  • Pneumatic Conveying
  • Long Distances
  • Abrasive Materials
  • Blended Batches
  • Fragile Materials
  • Powder Pump


Air and solids ratio controlled to 50 to 1 air to solids ratio (5:1 in typical dilute phase)

  • Low product degradation
  • Reduced product segregation
  • High convey rates and distances at relatively low pressures
  • Improved efficiency, resulting in reduced power consumption
  • No moving parts in operator zone (vacuum)
  • No liquid ring pump (no water consumption)
  • No booster
