Diffuser
A diffuser is an important part of heating, ventilation, and air conditioning (HVAC) systems that helps spread air evenly throughout a room or building. Think of it like a specialized vent cover that takes the air coming from the system and distributes it in a way that maximizes comfort and efficiency. When people mention diffusers in their resumes, they're typically talking about installing, maintaining, or designing air distribution systems. You might also see it referred to as an "air diffuser," "ceiling diffuser," or "ventilation diffuser."
