Amana-Goodman B2810814 3" Mesh Vent

The Amana-Goodman B2810814 Mesh Vent is a protective insert that fits into 3" PVC vent termination openings to prevent other elements from entering the vent path. It operates by allowing combustion air intake and gases to pass through a fine metal while external contaminants that could obstruct the pressure balance. It is positioned at the outdoor termination point of furnace vent piping and secured within the pipe opening for stable airflow routing in HVAC systems. It maintains clear vent passage and preserves combustion airflow consistency.
