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

無渦殼風機是用于在空氣處理機組中對風箱內的空氣進行增壓。具有高效的特點，并且無渦殼、無風管過渡段和擴壓段的設計使風機在空氣處理機內部節省了許多空間。有9片或者12片機翼式葉片兩種葉輪。
