System Overview<\/span><\/h2>\n
\n

Silent mixed flow inline duct fan is made for spaces where airflow must be strong, but the fan should almost disappear into the background.<\/p>\n

Its mixed-flow structure, EC motor and noise-reduction design help provide steady duct ventilation for residential, commercial, medical and light industrial environments.<\/p>\n

The fan gives installers a practical balance of airflow, pressure, quiet operation and service access.<\/p>\n <\/div>\n <\/section>\n\n

\n

Core Engineering Features<\/span><\/h2>\n

Built for quiet duct performance, this series combines mixed-flow pressure, EC control and modular maintenance.<\/p>\n

\n \n
\n
LOW NOISE<\/div>\n

Up to 30 dB reduction<\/h3>\n

Acoustic optimization helps reduce fan noise and improve comfort in occupied rooms.<\/p>\n <\/div>\n\n

\n
HIGH AIRFLOW<\/div>\n

Up to 1200 m3\/h<\/h3>\n

Strong airflow capacity supports larger rooms and longer duct paths.<\/p>\n <\/div>\n\n

\n
EC MOTOR<\/div>\n

Stepless speed adjustment<\/h3>\n

EC motor control helps tune airflow, noise and energy consumption for each project.<\/p>\n <\/div>\n\n

\n
LONG LIFE<\/div>\n

Durable continuous operation<\/h3>\n

The motor and fan assembly are designed for reliable long-hour ventilation.<\/p>\n <\/div>\n\n

\n
EASY SERVICE<\/div>\n

Modular no-tool structure<\/h3>\n

Tool-free access helps simplify inspection, cleaning and maintenance.<\/p>\n <\/div>\n\n

\n
DUCT FLEX<\/div>\n

90-degree connection support<\/h3>\n

Flexible inlet and outlet layouts make installation easier in tight duct spaces.<\/p>\n <\/div>\n <\/div>\n <\/section>\n\n\n
