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 PA3N250B48-RN0 IP55 EC-DC axial fan is a high-efficiency ventilation solution engineered for HVAC systems, industrial ventilation equipment, and air purification systems requiring high airflow with robust dust and water ingress protection. Powered by a 48V 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 dependable operation in demanding environments, while the compact Ø250×72.4mm design enables easy integration into space-constrained equipment.
Powered by advanced BLDC motor drive technology, this fan achieves significant energy savings compared to traditional AC induction motors, with input power of just 67.2 W and current draw of 1.4 A. Built-in locked-rotor protection, polarity protection, and auto-restart functionality ensure comprehensive motor safety in complex electrical environments. With Class B insulation rating, the motor windings maintain ample electrical safety margin even under high-temperature operating conditions. PBM is more than a fan manufacturer – we are your total industrial ventilation and thermal management system solution provider, delivering reliable, energy-efficient performance for your critical applications.
