The PS3N120B24-RZ0 120mm IP55 EC‑DC single inlet centrifugal blower is a high‑efficiency, safety extra‑low voltage (SELV) fan engineered for demanding applications that require high static pressure and robust dust/water protection – including residential and commercial cleaning appliances such as robot vacuums, floor scrubbers, and vacuum cleaners, as well as industrial dust collection and vacuum pickup systems, and air purification equipment 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 to ensure powerful dirt and liquid pickup. For industrial automation, this blower supports production line material handling and vacuum gripping, while in air purifiers it maintains consistent airflow through dense filtration media.
Delivering 24V DC rated voltage and IP55‑rated fully sealed construction, this high static pressure DC blower for robot vacuum and industrial dust collector fan ensures reliable, energy‑saving operation across all load conditions. PBM provides full engineering support from demand analysis and selection evaluation through prototype testing to mass production. Our 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 extraction, and other specialized applications. Whether you need a 640 Pa centrifugal fan for floor scrubber or a custom IP55 blower for vacuum pickup systems, PBM delivers precision‑engineered solutions for your unique requirements.
