Packing Details

PD3N133B48U is a 133mm DC Dual Inlet Blower fan made especially for air purifiers, fresh air systems, and heat pump systems. For a variety of HVAC and air purification equipment, it offers high static pressure, low noise, and small, dependable airflow performance. In addition to offering more equal airflow distribution and less vibration than single-inlet fans at the same rotational speed, the dual-inlet volute structure's dual-side air intake design greatly enhances airflow. It provides steady airflow even at high static pressure levels of 488 Pa, thanks to its 38-blade forward-curved impeller constructed of galvanized steel and refined volute channel design. It easily overcomes the accumulated resistance of HEPA filters and activated carbon filtering layers in air purifiers, as well as system resistance brought on by finned heat exchanger coils in heat pump systems, high-efficiency filters, and lengthy duct runs in fresh air systems.

PBM is an expert in the development and production of superior EC/DC fans and intelligent airflow solutions, enabling your air purifiers, fresh air systems, heat pump systems, and other equipment.
