Pneumatic Conveying Systems Built for Industrial Performance

IAC designs and builds complete pneumatic conveying systems for the safe, efficient movement of dry bulk materials in industrial environments. Our systems are engineered to handle powders, pellets, and granular materials with precision, ensuring consistent flow and reliable performance across a wide range of process conditions.

As a fully integrated EPC contractor and OEM, IAC provides complete design, fabrication, and installation of both pressure and vacuum conveying systems. Each system is configured to meet the specific requirements of the material and process, delivering dependable performance with minimal maintenance and downtime.

From concept to commissioning, IAC’s in-house engineering teams develop conveying solutions that optimize plant efficiency, improve environmental safety, and align with NFPA standards for dust collection and explosion prevention.

How Pneumatic Conveying Works?

A pneumatic conveying system is a material handling method that uses air pressure or vacuum to move bulk solids—like powders, granules, or pellets—through a pipeline from one location to another. These systems are commonly used in industries such as cement, chemicals, biomass, and food processing, where cleanliness, efficiency, and safety are critical.

There are two main types of conveying methods:

Dilute Phase Conveying: Ideal for non-abrasive, lightweight materials, this method suspends particles in a high-velocity airstream. It’s often used in applications requiring rapid transport and continuous flow.
Dense Phase Conveying: Uses a lower velocity, higher pressure approach to push heavier or abrasive materials in slug flow. This reduces wear and product degradation, making it ideal for fragile or high-value materials.

Depending on plant layout and material characteristics, systems can be configured as pressure conveying (blowing air) or vacuum conveying (pulling air). IAC provides both configurations and assists with selecting the optimal mode based on throughput, material density, particle size, and convey distance.

Integrated System Design

IAC’s pneumatic conveying systems are designed as part of a complete material handling solution that connects with upstream and downstream processes. Our engineers integrate conveying lines with storage silos, baghouses, filter receivers, and loadout systems to ensure smooth transfer of materials throughout the plant.

Each system is built for compatibility with automated controls, motor control centers, and process monitoring tools, allowing seamless operation and real-time data visibility. By combining conveying, dust collection, and storage into a unified design, IAC reduces material loss, simplifies maintenance, and improves plant efficiency.

Whether as a standalone installation or within a full EPC project, IAC systems deliver consistent material flow and reliable performance across a wide range of industrial environments.

Custom Engineering and Design

Every IAC pneumatic conveying system is custom engineered to match the material characteristics, flow requirements, and plant layout of each application. Our in-house engineering teams include specialists in mechanical, electrical, civil, and process disciplines who design systems that achieve precise control and reliable performance.

Using advanced 3D modeling and computational tools, IAC engineers evaluate airflow, pressure, and particle velocity to create efficient conveying routes that minimize energy use and component wear. Designs are built in accordance with NFPA and OSHA safety standards, ensuring compliance and long-term durability in demanding environments.

From concept and specification through fabrication and field installation, IAC’s design process focuses on optimizing performance, reducing maintenance costs, and extending the operational life of every conveying system.

Safety, Compliance, and Standards-Driven Design

IAC designs pneumatic conveying systems with a strong focus on operational safety and environmental compliance. Each system is engineered to meet or exceed industry standards, including NFPA guidelines for dust explosion prevention, OSHA workplace safety requirements, and MSHA standards for mining and bulk material handling environments.

Our engineering teams evaluate every element of the conveying process to reduce hazards such as static discharge, dust accumulation, or over-pressurization. System layouts incorporate explosion vents, isolation valves, and proper grounding to safeguard personnel and equipment.

By combining precise engineering with proven safety practices, IAC helps customers maintain compliance, protect their workforce, and operate efficiently in demanding industrial conditions.

Pneumatic Conveying System Components

Every IAC pneumatic conveying system is assembled from a carefully specified set of components engineered to withstand harsh operating environments and material demands. We supply complete systems as well as individual components for retrofits, upgrades, or replacements—backed by decades of application experience and over 55,000 SKUs in our parts inventory.
