Air Conveyors in Your Home

An air conveyor is any system that uses air to move an object from one place to another. You probably studied simple air conveyor systems when you were in middle school, learning about powering machines with air, such as by blowing an object across a table with a straw, or making a balloon-powered vehicle. These are fun projectsfavicon that show children how simple conveyor systems work. In your own home, you have several air conveyance systems that power everyday objects. From simple fans that circulate the air in your home to more complicated machines, there are at least two ways that you use air conveyors in your home:

Vacuums: Vacuums are the most obvious conveyor system in your home. Vacuums use the same power techniques as pneumatic industrial conveyors in factories and farms. The vacuum sucks up air and dirt into the machine, because the air pressure is lower inside the vacuum. High pressure air always travels to lower pressures, which is how a vacuum can work. This system is highly effective for removing dirt and dust from your floor, and it also works in industrial settings to move liquids and loose material from one place to another.

Leaf blowers: A leaf blower is an air conveyance system, but it is the opposite of a vacuum. A leaf blower uses pressurized air to blow out of the machine. This moves the leaves or other materials out of the way, and is an effective system for removing leaves and dirt from a driveway or patio. When these air pressure systems are used in industrial settings, they blow the air into contained tubes, which move the materials from one place to another. Because pressurized air is not as powerful as a vacuum, these tubes are used for shorter distances than vacuum conveyors.
