Packing Details

Dc backward curved centrifugal fan PB3N133B24U was created especially for industrial plant and cleanroom ventilation systems with the goal of offering a dependable and steady ventilation solution for settings where complicated duct resistance must be overcome. With a strong airflow of up to 750 m³/h and a static pressure of 488 Pa, this 133 mm DC backward curved centrifugal blower runs on 24V DC power. Its high static pressure efficiently eliminates the substantial air resistance brought on by several intricate bends, lengthy ducts, and multi-layered high-efficiency filters, guaranteeing accurate fresh air supply to specific locations. In addition, the fan ensures a comfortable working atmosphere by operating at just 62 dB(A) under challenging circumstances. Long-term steady and dependable performance in challenging situations like industrial dust and low humidity is ensured by its IP44 protection grade, 50,000-hour lifespan design, and extensive electronic protective features. Applications like cleanrooms, production line exhaust, chemical cabinets, labs, and precision manufacturing workshops that need to overcome high system resistance and guarantee directed ventilation will benefit from the PB3N133B24U. It is the best option for exhaust and ventilation in scientific and industrial research facilities.
