Purger, Air

Definition

An air purger is a mechanical device that removes unwanted air from a system.

Purpose

The purpose of an air purger is to eliminate air pockets from fluid systems, such as HVAC or plumbing systems, to ensure efficient operation and prevent damage or inefficiency caused by trapped air.

Examples of Use

• HVAC systems use air purgers to remove air from the heating and cooling circuits to maintain proper system pressure and efficiency.
• In hydronic heating systems, air purgers help prevent air locks that can disrupt water flow.
• Industrial fluid systems incorporate air purgers to ensure smooth operation and prevent cavitation in pumps.

Related Terms

• Air Vent: A device that allows air to escape from a fluid system.
• Degasser: A device that removes dissolved gases from liquids.
• Air Separator: A component that separates air from the fluid in a system.

Notes

Regular maintenance and proper installation of air purgers are essential to prevent issues such as noise, reduced efficiency, and potential damage to system components.
