Active Cooling for Industrial Control Enclosures
The FUJI NB2W90R-11 fan filter unit provides forced-air cooling for control cabinets and electrical panels. This unit draws ambient air through a washable filter, removing dust and debris before circulation. Sensitive electronic components benefit from this active thermal management solution.
Airflow Performance and Acoustic Ratings
This fan filter unit delivers an airflow rate of 90 cubic meters per hour at free air conditions. The unit operates at a noise level of 42 decibels, making it suitable for quiet working environments. An integrated temperature sensor activates the fan only when needed, saving energy. Furthermore, the unit includes a speed controller for adjustable airflow based on cooling demands.

Filter Design and Maintenance Access
The FUJI NB2W90R-11 incorporates a washable synthetic fiber filter with an aluminum frame. This filter captures airborne particles down to 10 microns with over 85% efficiency. Users can remove and wash the filter without special tools. Regular filter maintenance extends the fan life and maintains cooling efficiency.
Fan Technology and Speed Control
This unit employs a ball-bearing fan with a rated lifetime of 40,000 hours at 25°C. An integrated speed controller adjusts the airflow based on the actual cooling requirements. The fan automatically switches to maximum speed when the enclosure temperature exceeds the setpoint. This smart control reduces noise and energy consumption during partial load conditions.
Installation and Mounting Options
You can install this fan filter unit on cabinet doors, side panels, or top covers. The unit requires a 145 mm square cutout for flush mounting. Four mounting screws secure the unit to the enclosure with the provided gasket. The installation orientation allows unrestricted airflow through the filter.
Applications and System Compatibility
This fan filter unit suits control cabinets, drive enclosures, and power distribution panels. The unit works with various cabinet sizes and electronic loads. Multiple units can install in parallel for larger cooling capacity requirements. For best performance, position the unit near the heat-generating components and allow adequate exhaust ventilation.
