Air conveyors are most frequently employed to move soft goods like empty containers, boxes, and trays. A class of equipment known as an “air conveyor” uses air to transport goods and materials rather than mechanical belts or chains with speeds frequently reaching 1,000 fpm. They are not, however, just used with lightweight materials. Instead, materials-handling devices called air conveyors transport various things using pressurized air. Read More…

Air Conveyors Manufacturers List
They can be found in companies that produce and sell vast quantities of goods and, as a result, require machinery to help move those goods from one location to another quickly and effectively. These devices are also known as pneumatic conveyors.
Operational Principles of Air Conveyors
The earliest air conveyors consisted of a pipe with a blower attached to one end. Items like sawdust would be driven through the pipe by the air and enter the conveyor through a T-fitting or opening just downstream of the blower. Coal, grain, and scrap conveyors still use the same fundamental technology. Because the objects being carried are in the same plenum or pipe as the air moving them, these are known as internal air conveyors.
Blowers are another frequent type. A blower pressurizes a plenum, and air exits the plenum through various nozzles or louvers that are pointed toward the things to be moved and pushed in that direction. Items transported on these conveyors are typically held within low-friction guides to maintain orientation. The hybrid air conveyor, a less popular variation, uses two plenums. Louvers allow air to pass through to an inner plenum, where objects like scrap metal are moved.
Due to pressure losses inside a pipe, internal air conveyors can only be as long as 100 feet or fewer. Because air enters and exits throughout hybrid conveyors, they can be almost any length. Any friction between the product and air conveyors must be kept to a minimum because the force provided by air momentum imparted to the product is less than that caused by conventional conveyors (belts). Early closed air conveyors moved cargo via a smooth pipe, and an air boundary layer on the interior walls achieved minimal friction.
Types of Air Conveyors
Different air conveyors can be identified based on how they handle objects.
Deck conveyors attempt to lift products off the conveying surface but do not succeed—these transport items like cans, caps, and cartons or cases. Deck conveyors function similarly to air hockey tables, but in addition to the lifting holes, they also have directional louvers that direct the product's motion. Deck conveyors frequently have an angle of more than 10 degrees, and specialized air deck conveyors known as "tunnel tracks" for cans with decks on the top and bottom occasionally function as vertical elevators.
Deformed bottoms that scrape on the deck and delay or stop flow are sensitive to cartons and cases. Products transported on deck conveyors must rest uniformly on one side against the lifting apertures and louvers. If not, the product can vent the entire air intended to float it. A guide is typically needed to prevent products from toppling over. Typically, a top guide that is flat and parallel to the bottom surface is employed.
Neck Ring Conveyors
Plastic bottle neck ring conveyors transport bottles along a rail while capturing bottles by the ring (the region of the bottle just below the threaded portion the cap screws into). The conveyor's length is run by two low-friction tracks parallel to one another and placed side by side, similar to a train track.
The oldest application of air conveyors is likely to be bulk conveyors. Conveyors for simple bulk air are nothing more than tubes with blowers on one end. The airstream passing through the tube moves the material. Some bulk conveyors are completely covered, while others, like metal scrap conveyors, include openings on the top or one side. These conveyors employ louvers spaced regularly to keep the scrap stream moving. Bulk conveyors transport grains, bottle tops, powders, scrap, and coal.
Benefits and Drawbacks of Air Conveyors
Air conveying is a very dependable technology that can help a business save time and money and handle a wide range of materials. Asbestos, hazardous waste, wood chips, plastics, food, textiles, chemicals, gravel, coal, carbon black, metals, rocks, tablets, pellets, pills, sands, soils, grains, and powders are a few examples of these materials. Air conveyors also have some drawbacks, so they could be better. Air conveyors are more energy-intensive and cannot process materials with greater densities or larger particle sizes.
Sticky substances, gravel, and boulders are a few materials that should not be used in an air-conveying system. It is essential to ascertain whether the needed materials can be transported by air. Air conveyors are simple to operate around existing machinery and maintain. Due to all these features, air conveyors are a smart investment for a materials handling company. An experienced air conveyor manufacturer will help you locate the best suits for your application.
Applications of Air Conveyors
Air conveyor systems are employed for bulk handling of items in huge numbers, such as powders and food. They are among the most frequently used conveyor systems and come in various designs. In some situations, processing these materials by hand by employees is a more economical choice. However, it is far more advantageous for a machine to undertake this work in larger-scale manufacturing scenarios. Manufacturing procedures like assembly and packing lines would only be possible using conveyor systems. Mining, glass manufacturing, textile production, powder coating services, aviation and watercraft manufacture, pharmaceutical product research, plastic fabrication, and food and beverage processing are some industries that use air conveyors.
Choosing the Correct Air Conveyor Company
To make sure you have the most productive outcome when purchasing air conveyors from an air conveyor company, it is important to compare at least 4 to 5 companies using our air conveyor directory. Each air conveyor company has a business profile page that highlights their areas of experience and capabilities and a contact form to directly communicate with the company for more information or request a quote. Review each air conveyor company website using our proprietary website previewer to get an idea of what each company specializes in, and then use our simple RFQ form to contact multiple air conveyor companies with the same message.
