Product overview
Flexicon’s PNEUMATI-CON® dilute phase pneumatic conveying systems are custom-engineered to handle a wide range of bulk materials, from single-point “up-and-in” installations to cross-plant systems with multiple pick-up and discharge points. This conveying application moves bulk materials that are suspended in an air stream that is introduced by a positive pressure blower upstream of material intake points, or pulled through the system by a vacuum pump downstream of material discharge points. Material is separated from the air at the use point, then discharged on a batch basis via butterfly or slide gate valves, or continuously via rotary airlock valves.
VACUUM SYSTEM
Vacuum dilute phase pneumatic conveying systems are ideal for transferring materials from multiple sources such as storage vessels, process equipment, trucks, and railcars to one or more destinations with minimal heat impact and superior leak containment, making them especially suitable for handling hazardous or sensitive materials. These systems use a downstream vacuum pump to create a negative pressure differential in the conveying line, allowing for easy material pickup via rotary airlock valves, flexible screw conveyors, handheld wands, or flood feed adapters, and discharge through filter receivers or cyclone separators positioned above process equipment or storage points. Additionally, vacuum conveying supports direct feeding into enclosed vessels like blenders and reactors under vacuum, streamlining operations by eliminating the need for individual dust collection units at each discharge location.

FLEX-TUBE DIVERTERS, WYE DIVERTERS, FILL/PASS AND OTHER LINE DIVERTER CONFIGURATIONS
Flex-tube, wye and fill/pass diverters provide smooth transitions and selective routing to facilitate conveyor line configurations to meet any plant layout requirements. Line diverters enable more complex conveying line configurations by allowing materials to converge from multiple sources or diverge to various destinations, while fill/pass diverters support inline delivery along a single, continuous conveying path. Regardless of your plant layout or material flow requirements, the proper application of these valves ensures an efficient and effective conveying system.
ROTARY AIRLOCK VALVES IN ALL POPULAR DESIGNS AND SIZES
Rotary airlock valves deliver consistent metering of bulk materials while maintaining a pressure differential between pneumatic conveying system components and atmospheric pressure. At material inlets, rotary valves provide a consistent flow rate of product into a pneumatic conveyor ensuring steady material flow and stable conveying pressures. These valves can also be employed at material destinations to allow continuous discharge of material during the operation of a pneumatic conveyor. Engineered for versatility, these valves are available in a range of designs and sizes to suit various applications and flow rates.
Automation and Controls
Automation and Controls
Cyclone separators offer a streamlined solution for separating solid particles from a gas stream without the use of filters. Instead, they rely on cyclonic action and gravity. As air carrying material enters the separator tangentially, it spins rapidly to form a vortex. This motion generates centrifugal force, driving particles outward to the cyclone wall. Once separated, the particles descend through the bottom outlet into a process vessel, ensuring efficient, low maintenance operation in a wide range of applicatio
Automation and Controls
Silos, day bins, and other storage vessels provide secure, dependable storage for larger quantities of bulk materials for downstream processes. Available in carbon steel or stainless steel with industrial or sanitary finishes, these vessels are designed for durability and seamless integration within pneumatic conveying systems.
HAND-HELD PICK-UP WANDS
Hand-held pick-up wands provide a convenient way to introduce material into a vacuum pneumatic conveying system. They are ideal for mobile setups and allow operators to manually draw bulk solids from containers or other floor-level sources.
Automation and Controls
Flexicon systems include integrated controls and electrical components for automated operation and precise material handling. Customized for any application, these systems can be configured for manual, timed, or weight-based control of diverters and valves.

Total Evacuation
PNEUMATI-CON® systems completely evacuate both the source material vessel and conveyor line, virtually eliminating cross-contamination in applications with various materials. Pneumatic conveying systems ensure precise and complete material transfer, making them ideal for weigh batching applications where accurate delivery of weighed ingredients is critical. By fully transporting materials, these systems enhance batch quality and minimize waste, optimizing production efficiency.
Diversity of Products
Flexicon pneumatic conveyors offer versatility, capable of handling powders with a wide range of bulk densities, as well as flakes, pellets, capsules, tablets, and other material forms. This flexibility makes it easy to transport multiple ingredients using a single system.
Wide Capacity Range
With a PNEUMATI-CON conveyor, throughput can range from just a few pounds to tons per hour, feeding everything from small packaging lines to large silos and railcars. Even when feed rates fluctuate significantly, the system remains protected from overloading or underloading, ensuring reliable performance.
ENCLOSED SYSTEM PREVENTS CONTAMINATION
Designed for clean and secure operation, PNEUMATI-CON® conveying systems maintain a fully enclosed, dust-free environment. This helps prevent contamination of both the product and the plant, making them well-suited for transferring dusty materials.
EASE OF MAINTENANCE
Flexicon PNEUMATI-CON® systems are designed for easy maintenance, featuring filter receivers with convenient access doors and inspection ports. Rotary airlock valves can be equipped with optional rotor support bars, allowing straightforward access for cleaning and inspection to help reduce downtime and improve efficiency. In vacuum conveying applications, ultra-low maintenance Flexicon flexible screw conveyors can be used to meter product into the system.
MEET INDUSTRIAL AND SANITARY STANDARDS
PNEUMATI-CON® conveying systems are available in carbon steel with rugged industrial finishes or stainless steel designed to meet the standards of food, dairy, pharmaceutical, and other sanitary applications.
