Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design specs, ensuring the duct maintains its intended airflow geometry and sealing characteristics within the enclosure.

- Thermal Management Integrity — A correctly fitted duct channels cooling and exhaust airflow as designed, protecting sensitive generator components from heat buildup during extended run cycles.

The duct on a super-silent diesel generator is a formed channel that directs airflow — whether cooling air, exhaust, or both — through the acoustic enclosure in a controlled path. Proper airflow routing is critical to keeping internal temperatures within safe operating limits during continuous-duty use. When the duct cracks, deforms, or is missing, airflow becomes unmanaged inside the enclosure, which can cause hot spots, accelerated wear on nearby components, or reduced generator output over time.
