The word “pneumatic” aptly describes the nature of such conveying systems that utilize a medium such as air or nitrogen to gently move materials through desired horizontal and vertical pipe paths. Pneumatic conveying of bulk materials quickly, smoothly, and with minimal energy expenditure – a job for true professionals. Pneumatic conveying systems use differential air pressure to efficiently move materials from one point to another. As air flows from high pressure to low pressure, applying it to one end of the pipe moves the bulk material to the other end.
Production is categorized as either negative pressure systems that use a vacuum to pull the material or positive pressure devices that use a compressor to push the bulk material.

Production Benefits:
Ability to handle the product very gently
Control over the optimum level of fines and dust
Ability to operate in open/closed loop systems
Significant control over maintenance and adjustment time compared to mechanical pneumatic conveying systems
Fewer mechanical parts compared
What is production?
Product characteristics
(density, shape, size, permeability, resistance to damage, etc.)
Operating conditions
(temperature, altitude, etc.)
Production capacity
Site plan characteristics
(horizontal and vertical distances, space constraints, etc.)
And many more
Different production stages:
Dilute phase conveying
Which benefits from reliable operating ranges with a wide range at low pressure and relatively high conveying speeds.
Dense phase conveying
Which focuses on the design of conveying mild materials but is very sensitive in its operating range with high pressure values ​​and low conveying speeds.
Threaded Phase Transfer
which operates in a stable transfer phase between dilute and concentrated phases, with slower transfer velocities compared to the dilute phase.
