Technical Parameters

The MIWIND cabinet centrifugal fan series is built for ducted supply and exhaust applications that need more pressure than a basic axial fan. The listed range covers 2,000-25,000 m³/h airflow, 400-740 Pa pressure, 220 V and 380 V options, and approximately 55-79 dB noise depending on model and operating point.

Cabinet Centrifugal Fan Selection

Select the model from the required airflow at the connected static pressure. Include filters, grilles, dampers, heat exchangers, bends and duct length in the pressure calculation. The free-air maximum is not the delivered airflow after the fan is installed.

Applications and Airflow Planning

Cabinet centrifugal fans can support fresh-air supply, exhaust systems, workshops, warehouses, commercial buildings and process ventilation where the duct system has meaningful resistance. Compare the MIWIND fresh-air system range when the project needs filtered outdoor air or coordinated supply equipment. For odor, heat or moisture removal, also review the exhaust fan range.

Installation and Control

Provide a rigid base or suitable support, connect the duct without loading the cabinet, and leave room for motor and impeller service. Check rotation, grounding, protective devices and the rated voltage before commissioning. A speed controller, damper or BMS signal should be selected for the motor and project control strategy. Confirm sound at the occupied location and use vibration isolation where required.
