Diffusers are mechanical devices that slow the air and enhance its distribution within the space. What is their primary function?

• A. Slow the air and improve distribution
• B. Filter oil fumes
• C. Act as a heat source
• D. Increase air speed

Answer: (A)

Diffusers are meant to turn a focused, high-velocity supply air stream into a gentle, evenly spread flow throughout the room. By slowing the air and distributing it, they reduce drafts and help mix the fresh air with the room air, improving comfort and even temperature throughout the space. They’re not designed to filter fumes, serve as a heat source, or increase air speed—those roles belong to other components or systems. The aim of a diffuser is smooth, uniform distribution, not a strong jet of air.
