HVAC Replacement Parts of Air Louvers

Air louvers are essential HVAC components used to control airflow, provide ventilation, and protect ducts or equipment from unwanted elements like water, debris, and pests. Key parts of an air louver include the frame, blades (or vanes), and sometimes a screen or damper. Blades may be fixed or adjustable, allowing airflow control and deflection. Some louvers are designed for weather resistance, such as drainable or non-drainable models, which are common in outdoor applications to prevent water intrusion.
Signs of a faulty air louver include rattling noises, restricted airflow, visible rust or corrosion, and uneven temperature distribution. These problems often result from damaged or misaligned blades, clogged screens, or stuck dampers. Regular inspection and cleaning help maintain their performance and protect the system from external damage.

FAQs

Why is my air louver vibrating or noisy?

This may be due to loose blades or high airflow pressure. Secure the blades and check for balanced airflow.

What’s the difference between a damper and a louver?

A damper controls airflow inside ducts, while a louver typically allows or blocks air at openings, often providing weather protection.

Can air louvers prevent water intrusion?

Yes, water-resistant or drainable louvers are designed to deflect rain and moisture. Choose based on your building’s exposure and airflow needs.

Why is there reduced airflow through my louver?

It could be due to clogged blades, insect screens, or a poor louver selection. Clean or replace with a higher free area louver.
