Ventilation inlets

Special non-return dampers are used to prevent discharge air from the duct through non-performing high-pressure fans. They are mounted to a special pedestal surrounding the fan or directly to the fan. Intets are connected by means of massive loops at the damper edges. Inlets are closed when the fan is not running. When the operation is started, the damper blades are opened by the air pressure, taking a vertical position without obstructing the air passage.

The TKV inlet is made of quality wood covered with a special impregnation for protection against damage. Each size of the pressure fan corresponds to a certain type of valve: TKV-800, TKV-900, TKV-1000.
