Blower vs. Supercharger: Know the Difference

Shumaila Saeed
By Shumaila Saeed || Published on January 3, 2024
Blower generally refers to a device for moving air, while a supercharger is a specific type of blower designed to increase the pressure and density of air supplied to an internal combustion engine.
Blower vs. Supercharger

Key Differences

x A blower is a broad term for devices that move air or gases using blades, often found in various industrial, environmental, and household applications. Superchargers, on the other hand, are a specialized type of blower used specifically in automotive engineering to boost engine performance by compressing air, thus increasing its density before it enters the combustion chamber.

Blowers are used in a variety of settings, such as in HVAC systems, industrial processes, and cleaning devices, where their primary role is to create airflow. Superchargers, distinctively, are engineered to enhance the power output of an engine by forcing more air, and consequently more fuel, into the combustion chamber, resulting in increased horsepower.

The design of blowers varies widely based on their intended use, ranging from simple handheld devices to large industrial machines. Superchargers, however, are intricately designed to work in sync with an engine's operation, typically driven by a belt connected to the engine's crankshaft, to achieve the desired increase in air intake.

The term blower encompasses a wider range of devices beyond automotive uses, including environmental management, ventilation, and even personal grooming tools like hairdryers. Superchargers are more narrowly focused, almost exclusively used in the context of engine performance enhancement in vehicles, from cars to aircraft.

Blowers are generally focused on the efficient movement of air with varying degrees of pressure and volume, depending on the application. Superchargers, in contrast, are specifically designed to maximize the air pressure supplied to an engine, directly translating to a notable increase in the engine’s power and efficiency.
