An industrial air conveyor is a high-performance pneumatic material handling system designed to transform standard piping into a powerful transport line for bulk materials and small parts. By utilizing compressed air, these inline conveyors efficiently move materials such as sand, granules, capsules, screws, and bolts across production environments. Because the system features no moving parts, it provides a highly reliable, maintenance-free solution that eliminates the risk of mechanical wear or jamming. Ideal for streamlining industrial workflows, a pneumatic air conveyor integrates seamlessly into existing setups to provide a fast, consistent, and durable method for bulk solid transfer.
We offer two types of Air Conveyors in various sizes. Our non-threaded option has smooth ends allowing the user to install the Air Conveyor with a hose and clamp setup. We also offer an NPT threaded version which allows the user to thread the Air Conveyor to an NPT fitting or a coupling. Our Air Conveyors are also offered in aluminum or stainless steel material ranging in size from ¾” to 3”. Where extra moving force is required, one or more Air Conveyors can be mounted in a linear series to convey objects across greater distances.

(1) Compressed air enters the plenum chamber through an NPT inlet.
(2) An Air Conveyor insert redirects the compressed air, creating an amplified vacuum at the conveyor intake
(3) The amplified vacuum draws objects in and conveys them through the unit
(4) Objects exit the unit at a high velocity from the outlet, which enables them to be conveyed across long distances.
Important information
All Air Conveyors feature four ¼”-20 mounting holes along the rear face. Typically, they are held in place by a rigid hose to an L bracket. Please visit our “Accessories” section for optional L brackets.
At Supreme Air Products™, your facility’s safety is as critical as its efficiency. Our Air Conveyors are engineered to meet stringent OSHA noise and pressure standards, ensuring a safer acoustic environment for your operators while maintaining high-performance material transfer. Additionally, every unit is CE Compliant, meeting the rigorous health, safety, and environmental protection requirements for the European market. By choosing Supreme, you are investing in a “plug-and-play” solution that prioritizes global regulatory compliance without sacrificing industrial power.
The Threaded Air Conveyor is available in six standard IN-STOCK diameters of 1″ (25 mm), 1-1/4″ (32 mm), 1-1/2″ (38 mm), 2″ (51 mm), 2-1/2″ (64 mm), and 3″ (76 mm).
Mounting:
Connects in-line to convert ordinary tube and/or hose into a powerful conveying system for trim, scrap, parts and other bulk materials.
Air Supply Filtration:
A clean dry source of compressed air is vital! The Standard Kit includes an auto drain filter w/ a 5 micron filter, which is properly sized to avoid airflow restriction.

NOTE: There are generally four types of criteria to look for when selecting a proper model: the diameter of the parts being conveyed, the rate (weight or volume), the material of the Air Conveyor (stainless steel or aluminum), and the diameter of the hose and/or tube that is used. Call our factory at 1-647-876-6358 or email an Application Engineer at sales@supremeairproducts.com and let us help determine which model would suit your application.
The Supreme Air Products™ Air Conveyor is engineered exclusively for the high-velocity transfer of dry bulk materials and solids. While the system can tolerate trace amounts of moisture or damp air, it is not designed for the pneumatic transport of liquids. Attempting to convey liquids in bulk form will significantly reduce efficiency and may impede the vortex flow.
Yes. The Supreme Air Products™ Air Conveyor is highly effective at transporting powders and fine particulates. Because the system utilizes high-velocity air amplification to move material, the discharge end will contain a mixture of air and fine particles. To ensure a clean operation, we recommend integrating a centrifugal cyclone separator or a dust collection filter at the ejection point. This will efficiently decouple the air from the powder, ensuring a seamless and dust-free material transfer.
The Supreme Air Products™ Air Conveyor is engineered for high-efficiency material transfer, offering a standard amplification ratio of 9:1. This means the unit entrains ambient air from the suction intake at approximately nine times the rate of the compressed air consumed. This high-volume vacuum effect generates the massive airflow required to move heavy media or high-density solids over significant distances with minimal energy input.
For peak performance, the Supreme Air Conveyor should be positioned within 3 to 5 feet (1 to 1.5 meters) of the suction intake point. In pneumatic conveyance, it is significantly more energy-efficient to “push” material through a line using positive pressure than it is to “pull” it via vacuum over long distances. If your layout requires a longer run, always prioritize installing the unit as close to the material source as possible to maximize lift and minimize potential line clogs.
No. Standard Air Conveyors are not recommended for conveying flammable or explosive materials. The high-velocity friction of media moving through a conveyance line can generate a significant electrostatic charge. Without specialized explosion-proof engineering and verified grounding paths, this static discharge could act as an ignition source. For applications involving combustible dust or volatile solids, please consult our engineering team regarding specialized anti-static requirements and safety grounding protocols.
Supreme Air Products™ air conveyors are pneumatic devices that use a small amount of compressed air to create a powerful vacuum at one end and a high-velocity flow at the other. Because they have no moving parts and don’t require electricity, they are exceptionally reliable for moving materials through hoses or pipes.
Here are 10 of the most common applications for these air conveyors:
In plastic injection molding and extrusion, these conveyors are used to move raw resin pellets or granules from storage bins or gaylords directly into the machine hoppers. They prevent the need for manual lifting and ensure a steady supply of material.
In automotive and electronics assembly lines, air conveyors quickly transport small hardware like screws, rivets, bolts, and nuts to workstations or automated assembly robotic arms.
Used extensively in the bottling and packaging industries to move plastic or metal caps from a bulk hopper to the capping machine. The gentle air-driven flow prevents damage to the caps’ threads or finishes.
Because they are available in stainless steel (316L) for sanitary applications, they are ideal for moving delicate pills, capsules, or tablets between processing stages without crushing them.
Commonly used to transport lightweight food items such as bulk candy, dried beans, grains, nuts, or small snacks. Their enclosed design helps maintain hygiene and prevents contamination.
In CNC machining and metalworking, these conveyors suck up sharp metal chips, shavings, and turnings directly from the work area and transport them to a recycling bin, keeping the workspace clear and safe.
In printing and packaging plants, “edge trim” (the waste cut off from paper or plastic film rolls) is continuously sucked away from the cutting blades and sent to a waste collector to prevent machine jams.
They are frequently used as “spot” vacuums to remove sawdust, textile lint, or fine particulates from a production line where traditional vacuum cleaners would be too bulky or maintenance-heavy.
Manufacturers use them to move small mechanical components, like ball bearings or stamped metal parts, through various stages of inspection and assembly without manual handling.
Stainless steel and heat-treated versions of these conveyors are used to move abrasive materials like sand, glass beads (for blasting), or garnet. Since there are no internal moving parts for the grit to grind down, they outlast mechanical conveyors in these harsh environments.
