Vortex S-600-D is a 6-inch inline duct fan designed for high-performance air and sound management in various applications. Its mixed-flow impeller ensures quiet operation and high airflow, making it suitable for noise-sensitive environments. The double-insulated wall prevents condensation and reduces noise levels, while the rubber duct connection gasket ensures an airtight connection and neutralizes vibration. The fan's durable polycarbonate casing withstands heavy-duty use, and its integrated backdraft damper prevents air leakage when not operating.
