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.
Electric-powered blowers require an electrical power source provided from an electrical outlet, through an extension cord. Cordless blowers, on the other hand, use rechargeable batteries and are more suitable for smaller areas because of their limited operating time. Mixing oil and gasoline operates gas-powered leaf blowers. 2-stroke gasoline engines generally power backpack blowers, while wheeled units generally have 4-stroke gasoline engines.
Snow blowers can be single-stage and two-stage. The former is a light duty machine that uses a single high-speed impeller (a rotor inside a tube) to pull in snow and expel it from a discharge chute. Two-stage snow blowers on the other hand, are heavy duty and have more than one low-speed metal auger that pull the snow into an impeller, which then discharges the snow into a chute.

Leaf blowers can be handheld, backpack or wheeled. Handhelds are most suitable for simple, home maintenance works. Backpack blowers are swift, has quick throttle response and fuel efficient and generally preferred by professionals. Wheeled or walk-behind leaf blowers are the best for maintaining larger areas and are mostly gas-powered.
Industrial blowers are manufactured using a range of durable plastics and metals, or a combination of both materials. Function includes drying, reducing heat levels, reducing smoke and odors, processing and controlling gaseous fumes in industrial settings like factories.
Blowers provides detailed information about blowers, backpack blowers, blower fans, blower motors and more. Blowers is the sister site of Electric Pressure Washers.

Backpack Blowers
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.
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.
