Air Conveyors Information Air conveyors are devices that use airflow to move items or media. There are many different types of products. Examples include vacuum conveyors, pneumatic tube conveyors, and air tables. Vacuum conveyors consist of a perforated belt, vacuum source, nozzles, filters, and tubing. Products are placed flat on the belt to create a seal. Pneumatic tube conveyors or air conveyors use low-pressure air to push or pull a short, closed cylinder through a pipe between origin and...

Applications and UseTop

Q:
What are some of the applications you have used an air conveyor for?
37 answers
Answers:

Hospitals, Car Dealerships, Movie Theatres, Home Depots, Costco's, Banks, Grocery Stores, Industrial Warehouses and many small industrial applications, too numerous to list.

~Gordon T, Operations Manager/Project Engineer, Anaheim, CA

I have worked on the transport of dust through air in the facilities of a clay processing factory for pharmaceutical purposes. More specifically, I was responsible for the installation of machinery (blower) and pipe lines according to a project that had been developed by an American firm. During the installation of the machinery, there was a collision between two pipe lines due to a miscalculation in the project. Therefore, I had to make specific changes in the piping system in order to make the installation possible. I referred to Russian technical literature in order to study similar processes. It is important to note that whenever there should be practical interventions in the pipe line system implementation regarding the transport of material through air, the pipe’s length should not be changed from the one it was designed in the project and there should not be additional turns along the pipeline system.

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of an air conveyor?
11 answers
Answers:
Too many to list. 1. Buy quality, low dollar systems may not be the most economical. 2. A system designed for one product or even a grade of product may not work at all with a different product or grade. 3. Testing with a supplier is always a good idea especially if the product is not common. 4. Purchase installation and/or start-up assistance from supplier. 5. There are consultants that exist but be cautious because they may have a systems supplier that they typically work with.
~Al G, Senior Project Engineer, Houston, TX
Check the ongoing maintenance requirements for the conveyor and all other equipment that interfaces with the conveyor such as feeders and chute systems.

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using air conveyors?
14 answers
Answers:
Use a reliable supplier, be sure to provide the properties of the product you are transporting to this conveyor, and other technical details of the installation, transport capacity required, transport line distance and the line layout. Ask for the technical specification of the unit and discuss this thoroughly with the supplier before finalizing the order.
~Antonio Anduyo, Facilities Manager, Cebu city, Philippines

1. While buying air conveyors for bulk solid material, please always try to find out if any prototype design is available with the supplier. A miniature plant will solve most of the issues as the characteristic of the material plays vital role in conveying.

~Gunasekaran R, Project Manager, Chennai, India

Air conveying systems, when designed, installed, and maintained properly, can be a plant's dream. There are only a few E&C Companies that have in-house expertise with the experience to ensure proper systems for various products.
