Dense phase pneumatic conveying system
Fluid Airsystems

FLUID AIRSYSTEMS has consolidated handling experience thanks to the development of dense-phase pneumatic conveying systems with pulsating air. One of the main characteristics of these systems is their simplified design which is based on a single transfer conduit, without additional injections, built with stainless carbon steel 304-316, polyethylene and hoses. A manual or automatic valve can be used to adjust the quantity of material being handled (flow rate).
In the automatic version, the valve, along with a pressure switch, acts like an anti-lockout device. When the conveying pressure increases beyond the standard value, the valve prevents the material from entering the piping until the pressure drops below the conveying pressure value, re-enabling the regular feed process.
During a sudden power outage, a dual valve system, in which one valve is normally closed and the other normally open, guarantees a continuous supply of compressed air.
For a sudden interruption in the compressed air supply, a small compressed air tank ensures that conveying will continue until the line has been emptied, while the material feed system on the same line is closed automatically.
