The Delta TDA series fan is equipped with a special cone shape impeller hub to spread the air flow wider from exhaust outlet to cover more area. When arranged in parallel, the overlap of air flow of each fan will cover each other to make sure air flows to its original designated area even under the condition of fan failure. Steady speed across operation range, the IP55 rated TDA series is available with PWM signal speed control and speed signal output. TDA’s life expectancy is designed to be as high as 100K hours.
