Packing Details

120mm EC Single Inlet Blower made especially for Clean Electrical Appliances, Sweeping Robot is the PS3N120B2EM. Its dual-mode stepless speed control (0–10 VDC/PWM) allows for real-time airflow modification based on the robot vacuum's dustbin load and floor material sensors. This produces "on-demand suction," which is especially useful for robot vacuums that combine sweeping and mopping and need to run for extended periods of time. It also avoids the battery loss and needless energy waste produced by fixed-speed fans. It provides steady airflow even at high static pressure levels of 471 Pa because to its 34-blade galvanized steel forward-curved impeller and efficient volute channel design. It easily overcomes the accumulated resistance brought on by the dustbin filter, HEPA filter, airflow bends, and dust-air separation devices inside the robot vacuum system when combined with an aerodynamically optimized streamlined airflow route.

PBM is an expert in the development and production of superior EC/DC fans and intelligent airflow solutions. The robot vacuum's main control unit (MCU) can precisely monitor it thanks to its support for speed signal output (FG), which makes system integration easier. It can exactly match the cleaning system's constant airflow or constant static pressure control techniques when combined with 0–10V/PWM speed control, satisfying the dynamic suction level needs for various floor materials and filth levels. On request, we provide OEM modification services that include compatibility with acoustic foam accessories, compact size adaptations, protection rating upgrades (up to IP55), and particular wiring configurations.
