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(fēng)機(jī)是用于在空氣處理機(jī)組中對風(fēng)箱內(nèi)的空氣進(jìn)行增壓。具有高效的特點(diǎn)，并且無渦殼、無風(fēng)管過渡段和擴(kuò)壓段的設(shè)計(jì)使風(fēng)機(jī)在空氣處理機(jī)內(nèi)部節(jié)省了許多空間。有9片或者12片機(jī)翼式葉片兩種葉輪。
