The static pressure of centrifugal fan in low noise cabinet can definitely meet the length of pipeline, and the specific parameters need to be known in detail. The low-noise cabinet centrifugal fan is a new product successfully redesigned to meet the requirements of air conditioning, purification industry and environmental protection and noise reduction by using the principle of combining aerodynamics and aeroacoustics on the premise of digesting and absorbing advanced technologies at home and abroad. It has the characteristics of large air volume, high total pressure, low noise and small vibration, which meets the requirements of environmental protection and labor protection.
