FOCUS ON EC FAN ONLY
PS3N160B48M is a 160mm DC single-inlet centrifugal fan specifically designed for air purification. It draws in contaminated indoor air, propels the airflow sequentially through multiple filter stages, and returns the purified air to the room as a directed airflow. Its medium-to-high static pressure of 620 Pa effectively overcomes the cumulative resistance created by combinations of HEPA filters, activated carbon filters, and pre-filters. Whether the air purifier is in its initial installation state or the filters are nearing the end of their service life, it maintains a stable clean airflow, ensuring that the CADR does not decline. This extends the effective replacement cycle of the filters and reduces long-term maintenance costs for users.
PBM specializes in the R&D and manufacturing of high-quality EC/DC fans and intelligent airflow solutions. To address the diverse needs of air purifier and cleanroom equipment manufacturers, PBM offers specialized customization services.
