THD series innovation with bionic blade fan


The THD series boasts newly designed bionic blades inspired by nature’s most powerful winged predators. This fan series represents the most quiet, powerful, and efficient design Delta has to offer. Engineers managed to apply the posture and wing structures of an osprey in flight to design fan blades via parameterized and simulated processes. By simulating the curve of an osprey’s wing in flight, the new THD series fan reduces fan noise up to 6dB-A. THD fans offer different sizes of products, from SQ80mm to OD200mm


  • Higher performance at lower noise
  • More powerful cooling solution
  • 45% higher bionic fan efficiency
  • High strength blade design
  • Advanced motor driving tech
