What is the difference between an air wrench and an impact wrench?

An air wrench and an impact wrench are two different types of power tools commonly used for tightening or loosening fasteners. While they have similar functions, there are some key differences between the two:

    Power Source:
        Air Wrench: An air wrench, also known as an air ratchet, operates using compressed air. It requires an air compressor to generate the necessary power. Air wrenches are popular in automotive and industrial settings due to their high torque and rapid operation.
        Impact Wrench: An impact wrench can be powered by various sources, including compressed air, electricity (corded), or batteries (cordless). The most common types are pneumatic (air-powered) and cordless impact wrenches. Cordless impact wrenches are highly portable and offer more freedom of movement.

    Operation:
        Air Wrench: An air wrench uses a ratcheting mechanism similar to a manual ratchet wrench. It provides continuous rotational motion when the trigger is engaged, allowing for faster tightening or loosening of fasteners. Air wrenches are typically used for lighter-duty applications.
        Impact Wrench: An impact wrench utilizes a hammering or percussive mechanism to deliver sudden, high-torque bursts. When the trigger is pulled, the wrench applies a series of rapid, hammer-like impacts to the fastener. This mechanism enables high torque output, making impact wrenches suitable for heavy-duty applications and stubborn fasteners.

    Torque Output:
        Air Wrench: Air wrenches typically have lower torque outputs compared to impact wrenches. They are designed for lighter-duty tasks that do not require extreme torque. Air wrenches are commonly used for applications such as automotive repair, small machinery, and assembly work.
        Impact Wrench: Impact wrenches are known for their high torque outputs, making them ideal for heavy-duty applications. They can deliver significantly more torque compared to air wrenches, allowing for the removal of stubborn or tightly secured fasteners. Impact wrenches are commonly used in automotive repair, construction, manufacturing, and other industrial applications.

    Versatility:
        Air Wrench: Air wrenches are primarily used for applications that require quick tightening or loosening of fasteners in confined spaces. They are often used in automotive repair shops and assembly lines due to their compact size and maneuverability.
        Impact Wrench: Impact wrenches are more versatile and can be used for a wider range of applications. They can handle heavy-duty tasks such as automotive maintenance, construction projects, equipment assembly, and industrial maintenance.
