Pneumatic conveyors transport powders, granules and other bulk materials through enclosed pipelines. Instead of belts or mechanical systems, they use airflow to move materials through production stages. Because the process is enclosed, it helps reduce dust and supports flexible layouts in many industries.
Pressure Pneumatic Conveyors
Pressure pneumatic conveyors push materials through pipelines using compressed air from a blower or compressor. Material enters through a pressure vessel or rotary airlock before moving through the line. These pneumatic conveying systems are often used for longer conveying distances and higher capacity installations.
Vacuum Pneumatic Conveyors
Vacuum pneumatic conveyors draw material through pipelines using negative pressure. The product moves towards a receiving vessel where air and material separate. Vacuum based pneumatic conveying systems are often used where cleanliness and dust control are important.

Dense Phase Pneumatic Conveyors
Dense phase conveyors operate at lower air speed but higher pressure. Materials travel through the pipe in compact plugs rather than remaining suspended. This approach is gentler on products and reduces wear inside the pipeline. Dense phase pneumatic conveying systems are often used for delicate powders or abrasive materials.
Dilute Phase Pneumatic Conveyors
Dilute phase conveyors move materials at high air velocity. Particles remain suspended in the air stream as they travel through the pipeline in continuous flow. This makes dilute phase pneumatic conveying systems a common choice because the equipment is relatively simple. They are often used for free-flowing powders and granules in food ingredients, and chemical processing.
