High-efficiency EC motor, significant energy savings<\/h4>\n

\u2013 Conversion efficiency exceeds 90%, saving 30-50% more electricity than comparable AC fans.<\/p>\n

Stepless speed regulation, precise airflow control<\/h4>\n

\u2013 Supports PWM or 0-10V analog speed regulation, perfectly matching temperature control systems.<\/p>\n

High airflow, low noise operation<\/h4>\n

\u2013 Optimized fan blade and rectifier design, noise level at maximum speed is only 52 dB(A).<\/p>\n

Robust and durable, adaptable to harsh environments<\/h4>\n

\u2013 IP54 protection rating (depending on actual conditions), wide operating temperature range of -25~+60\u2103, maintenance-free bearings.<\/p>\n
