Aero Acoustic Diffuser™
E-Series Plenum Fans
Traditional acoustic silencers attenuate sound at the expense of additional pressure drop resulting in higher power consumption and lower aerodynamic efficiencies.
Twin City Fan and Blower’s patented Aero Acoustic Diffuser™ achieves discharge sound power reduction by up to 3dBA. Static pressure is boosted and aerodynamic static efficiency increases by up to 4%.
When used with Twin City Fan’s E-Series plenum fans, static efficiency up to 80% is achieved on a size 365 (36.5″ wheel diameter)…the best in the industry.
Higher air handling unit system pressure drops, equating to more coil rows or high efficiency filters, can be handled with the same size fan running at the same speed. In certain cases, a smaller size fan may be selected for a given application.
Application
无涡壳风机是用于在空气处理机组中对风箱内的空气进行增压。具有高效的特点,并且无涡壳、无风管过渡段和扩压段的设计使风机在空气处理机内部节省了许多空间。有9片或者12片机翼式叶片两种叶轮。
AMCA认证的声强和空气动力性能
UL705认证
