高效送風口 HEPA-BOX
高效送風口 HEPA-BOX 
高效過濾器送風口又稱高效過濾器送風靜壓箱，是高效過濾器應用于送風系統中的中間裝置，目的是為了空氣在通過高效過濾器之前獲得理想的靜壓，使高效過濾器得到合理的使用。其特點是結構緊湊、性能可靠、通風性強、安裝方便、維護簡單。DOP、壓差檢測口，液槽、下調式風閥，旋流等各類擴散面板，一應俱全。
HEPA-BOX is an intermediate equipment of high efficiency filter applied in air supply system and its aim is to get desired static pressure before air pass through high efficiency filter to make high efficiency filter be used reasonably; its character is compact structure, reliable performance, well ventilated, convenient to install and easy to maintain; it has all kind of diffusion panels such as DOP, differential pressure inspecting port, flume, down mode air valve and rotational flow.
