Backpack blowers are more commonly used by professionals and are mostly powered by 2-stroke gasoline engines. The harness, which has a blower fit into it, is worn on the operator's back. The engine and fan are also placed on the backpack frame with a hand-held hose and spout to direct the airflow. Backpack blowers are powerful, convenient and have larger, more efficient fuel tanks and air filters and therefore, longer duty cycles.
Backpack blowers with more than 40cc engines are the best with a typical blowing power of 400 cfm (cubic feet per minute) of volume at 190 mph (meter per hour). If you live in a quiet neighborhood, these units are the best choice, because they are specially assembled to control unwanted noise. Also, keep in mind that harness quality and comfort differ from one model to the other.
Performance backpack blowers generally have blowing power of more than 450 cfm of volume at 195 mph, and are named because of their high performance. Though they may be noisier than other blowers, they are fast, fuel efficient, and have a quick throttle response. Most professionals and commercial users prefer this type of units, which also has optional accessories like breathable nylon back pads and padded, adjustable harnesses.

Blowers
There are many types of Blowers -- leaf blowers, industrial blowers, snow blowers, etc, Each type has different subtypes such as backpack, handheld, corded and cordless, wheeled, electric-powered and gas-powered, and so on. Each type and subtype differs in function and purposes. For example, while some of them may be specifically manufactured for home maintenance, other more powerful units are aimed at commercial users.
Blower Fans
Fans utilize power from a motor to generate a volumetric flow of air at a given pressure, and are considered low-pressure air pumps more often than not. A propeller converts torque (turning force) from the motor (typically permanent split capacitor AC induction motors or brushless DC) to increase static pressure across the fan rotor and to increase the kinetic energy of the air particles.
Leaf Blowers
Leaf blowers were first manufactured in Japan during the 1970s, and made their debut in the Untied States towards the end of the decade. The annual sales by 1990, reached an estimated 800,000 in the country. It has become very popular due to its efficiency and effectiveness in ground maintenance. Today, leaf blowers are used by almost every family for cleaning patios, lawn trash, leaves, etc.
Cordless Blowers
Cordless Blowers are portable units normally intended for homeowners in indoor or light duty outdoor maintenance. Even though they are less powerful in comparison to gas-powered or electric-powered blowers, they are perfect for sawdust or grass clippings.
