Packing Details

355mm DC back-curved centrifugal fan B3N355B24H was created especially for HVAC systems and data center and communications heat dissipation. It outperforms industrial centrifugal fans with comparable airflow capacity, with a recorded noise level of only 70 dB(A). In manned equipment rooms, fan section ceilings, and air conditioning equipment rooms, it may function steadily and with little disruption. It is the perfect aerodynamic solution for HVAC systems and communications heat dissipation applications because of its very thin 115mm body design, which enables flexible integration into a variety of equipment enclosures.

PPM specializes in the development and production of superior EC/DC fans and intelligent airflow systems. PBM provides a range of specialized services to satisfy the various requirements of manufacturers of communications equipment and HVAC system integrators.
