Which of the following is NOT an example of equipment powered by air compressors?

The correct answer highlights that electric saws are not powered by air compressors. Unlike pneumatic tools, which rely on compressed air supplied by compressors for operation, electric saws use electrical power to function. This distinction is key; pneumatic wrenches, paint spray booths, and lifts in auto service stations are all examples of equipment that utilize compressed air to perform their tasks efficiently.

Pneumatic wrenches are specifically designed to deliver high torque and speed through air pressure, making them ideal for automotive and industrial applications. Paint spray booths often use air-powered spray guns to achieve a fine mist of paint and manage the airflow during the painting process. Similarly, lifts in auto service stations may utilize air pressure to operate hydraulic systems that elevate vehicles for maintenance. Each of these tools and systems demonstrates the versatility and power of air compressors in various settings, while electric saws operate on a completely different power source, emphasizing the separation between electric and pneumatic equipment choices.
