FOCUS ON EC FAN ONLY
133mm EC Dual Inlet Blower made especially for Seat Ventilation is the PD3N133B2EM. For enclosed areas like car interiors where silent operation is essential, the dual-intake design guarantees high static pressure while attaining lower vibration levels. For a variety of seat ventilation systems, it offers small, dependable airflow performance, minimal noise, and high static pressure. With a galvanized steel forward-curved impeller with 38 blades and an improved volute channel design, it can sustain steady airflow even at 500 Pa of static pressure. In enclosed vehicle conditions, its low noise level of 65 dB(A) guarantees that it will not impair driving and riding comfort. The device has an IP44 protection grade and operates in a temperature range of -25°C to 60°C, allowing for long-term steady operation in settings with extreme vibration and temperature swings, such the seats of construction and automotive gear.
PBM is an expert in the development and production of superior EC/DC fans and intelligent airflow solutions. Through system integration with the seat control unit (SCU), the unit is support for speed signal output (FG) enables accurate monitoring. It can accurately match the constant airflow or constant static pressure control techniques of seat ventilation systems when combined with 0–10V/PWM speed control, satisfying passengers' comfort needs across various airflow settings.
