FOCUS ON EC FAN ONLY
PBM FOCUS ON EC FAN ONLY. Certificate: CE,UL,ROHS; Supply Ability: 100,000 pcs per year; MOQ: 1~100 pcs based on EXW price; 100 pcs above based on FOB price.
This PA3N250B24-RN0 IP55 EC-DC axial fan is a high-performance ventilation solution purpose-built for HVAC systems, industrial ventilation equipment, and air purification systems requiring high airflow with reliable dust and water ingress protection. Powered by a 24V DC safety extra-low voltage (SELV) motor at 2500 RPM, it delivers 1700 m³/h airflow with 220 Pa static pressure. The fully sealed IP55-rated construction ensures durable operation in demanding environments, while the compact Ø250×72.4mm design enables flexible integration into space-constrained equipment.
Engineered for intelligent system integration, this fan supports 0-10V DC and PWM dual-mode stepless speed control, allowing system integrators to dynamically adjust fan speed based on real-time ventilation demands for precise airflow management and energy optimization. The integrated FG (frequency generator) tachometer feedback signal output enables the main control board to monitor real-time fan status, supporting closed-loop speed regulation and predictive fault alerts. With over 15 years of expertise in DC/EC motor and fan technology, PBM ensures each axial fan strictly complies with international safety standards (CE certified), delivering reliable, energy-efficient performance for your critical ventilation applications.
