The PS3N120B48-RZ0 120mm IP55 EC‑DC single inlet centrifugal blower is a safety extra‑low voltage (SELV), high‑efficiency fan engineered for applications that demand high static pressure and robust environmental protection – including residential and commercial cleaning appliances such as robot vacuums, floor scrubbers, and vacuum cleaners; industrial dust collection and vacuum pickup systems for workshop dust extraction and automated material handling; and air purification systems including small to medium air purifiers and energy recovery ventilators. In cleaning appliances, its 640 Pa high static pressure effectively overcomes system resistance from dust box filters, HEPA cartridges, and duct elbows, ensuring powerful dirt and liquid pickup. For industrial automation, this blower supports production line dust collection and vacuum gripping, while in air purifiers it maintains consistent airflow through dense filtration media.
Operating at 48V DC rated voltage with IP55‑rated fully sealed construction, this high static pressure 48V blower for robot vacuums and industrial dust extraction fan with 640 Pa delivers safe, reliable, energy‑saving performance in low‑voltage environments. PBM's OEM customization services cover multiple dimensions – including custom lead wire configurations, compact size adaptations, and optional silencer accessories – tailored specifically for cleaning appliances, industrial dust collectors, and air purifiers. Whether you need a 640 Pa centrifugal fan for floor scrubber, a custom SELV blower for HEPA‑filtered air purifiers, or a silencer‑equipped fan for quiet operation, PBM delivers precision‑engineered solutions for your unique requirements.
