A sound attenuator is a noise-reducing device used in HVAC systems to minimize sound transmission through ductwork while maintaining efficient airflow.

A flexible canvas connection is an HVAC duct connector made of durable, flexible fabric that helps absorb vibrations and noise between air ducts and mechanical equipment.

Isolators are vibration-damping devices used in HVAC systems to minimize mechanical vibrations and prevent them from being transferred to surrounding structures.
