Packing Details

PB3N310B24U product is a 310mm DC backward centrifugal fan intended for server cabinets and server room cooling systems, including hot aisle enclosed auxiliary cooling, rack-mounted cooling units, row air conditioners, high-density computing node air walls, raised floor plenum air supply systems, and other data center hardware.

Even when the server cabinet's front door is equipped with high-density mesh, the rear door hot aisle is sealed, and a multi-layer air filter is used, the cold air flow can still penetrate all wind resistance and reach each server's air inlet, maintaining the heat exchange efficiency without attenuation thanks to the ultra-high static pressure of 640 Pa and the large air volume output of 2200 m³/h. Based on cutting-edge air supply technology, it is the perfect option for a variety of medium-sized and large data centers to meet the heat dissipation requirements of high-density equipment. In order to support customized services, PBM completely collaborates with goods such row air conditioners, server cabinet integration, and air wall auxiliary cooling. PBM is also heavily involved in high-quality EC/DC fans and intelligent air flow control technology.
