  • Dense Phase Pneumatic Conveying – Cyclonaire

    Dense phase pneumatic conveying is a relatively low-speed system where the material is not suspended in the air stream The low velocity of dense phase means less wear and tear on both the system and the materials being conveyed The velocity is typically set between 400 ft/min and 1,000 ft/min, though there are several forms of dense.
