功能

• Tabletop exhaust hood that can be used from both sides.
• Non-pole type with no columns left in the middle of the front sash, so the hood is wide and the work in the center can be done smoothly.
• With VAV automatic exhaust control, it is economical (energy saving) to exhaust according to the opening condition of the sash.
• Considering the frequency at which the sash is opened at the same time, the total displacement can be considered, thus minimizing the exhaust duct size and fan, thereby reducing the initial cost.
