Air Separator
An Air Separator is a device used in heating and cooling systems to remove unwanted air bubbles from the water that flows through pipes. Think of it like a filter that catches air before it can cause problems. This is important because air in heating systems can cause noise (like banging pipes), reduce heating efficiency, and potentially damage equipment. You might also see these devices called "air eliminators" or "air removal devices." These are common in both residential and commercial building heating systems.
