Solid, Granular & powdered materials have been handled conventionally, by mechanical conveying equipments such as belt conveyors/screw conveyors/ bucket elevators/ goods lifts etc.

This newer concept is making the solids airborne, in a fluid state, with the help of air or an inert gas traveling in a closed pipeline. The concept was found very attractive due to a closed pipeline conveying & was picked up by most industries for handling of solids pneumatically, in the last three decades.

Depending on the product characteristics, air volume & pressures are applied at the design stage. These parameters categorise the systems as either the DENSE Phase Pneumatic Conveying System or DILUTE / LEAN Phase Pneumatic Conveying System.

TECHFLOW designs and manufactures Pneuma-LeanX lean/dilute phase conveying systems for vacuum conveying. In this system, the material is conveyed with the help of a Centrifugal Blower/Roots Blower/Regenerative Blower, for example, a powder conveying system employs both pressure and vacuum to transport materials as they were liquids vertically and horizontally to and from process devices. Here material is conveyed either by negative suction or by positive pressure of blower.
