The Delta TEA series is designed to replace backward-ward curved impellers. The airflow path turns 90 degree inside the impeller. That is airflow sucked from axial direction then thrust radically. The scroll guides the air to exhaust. Comparing with same size of traditional backward-ward curved impellers, Delta TEA Series has lower noise, higher performance, high efficiency which lowers power consumption. TEA series is available with PWM signal speed control and speed signal output.
