I. kitchen ventilation

　　1)對于室內直排油煙的廚房(即排風口在室內墻上)，可以根據油煙大小選擇SF型軸流風機或FA型排氣風扇。

　　1) for the indoor cooking fume hood (that is, the exhaust air on the indoor wall), the SF axial fan or FA exhaust fan can be selected according to the soot size.

　　2)山東通風管道加工對于油煙大，且油煙需要經由長管道，并管道里有打彎處理的廚房，強烈建議使用離心風機(4-72離心風機為通用，11-62低噪聲型離心風機也很實用)，這是因為離心風機的壓力較軸流風機大，且油煙不經過電機，對電機的保養(yǎng)和換洗更容易。

　　2) for smoke, and smoke through long pipes, and the pipe is bent with the kitchen, strongly recommend the use of centrifugal fan (4-72 centrifugal fan is the most common, 11-62 low noise environmental protection type centrifugal fan is also very practical), this is because of the centrifugal fan pressure is relatively large axial flow fan don't smoke, and through the motor, easier for motor maintenance and change.

　　二.高檔場所通風。對于酒店、茶坊、咖啡吧、棋牌室、卡拉OK廳等高檔場所通風，就不適宜用常規(guī)風機了。

　　Two. Ventilation in high-grade places. For the hotel, tea house, coffee bar, chess room, Cara OK hall and other high places is not suitable for conventional ventilation fan.

　　1)對于小室的通風，使通風管道連接通風管的房間，可以在兼顧外觀與噪聲基礎上，選擇小型軸流風機，體積小，塑料或鋁制外觀，低噪聲與高風量并存。

　　1) for cabin ventilation, ventilation pipe connecting central ventilation pipe to the room, in both appearance and noise based on the selection of small axial flow fan, small volume, plastic or aluminum appearance, both low noise and high volume.

　　2)風量與噪聲要求更嚴格的角度說，風機箱是好選擇。箱體內部有消音棉，外接通風管道后可以達到減噪的顯著效果。

　　2) wind and noise requirements more stringent point of view, the wind box is the best choice. The inside of the box is provided with noise proof cotton, and the remarkable effect of noise reduction can be achieved after the central ventilation pipe is externally connected.

　　3)對于健身房的室內吹風，務必選則大風量的工業(yè)電風扇，而非SF型崗位式軸流風機。這是從外觀及性方面考慮。

　　3) for indoor air blowing in gymnasium, it is important to choose an industrial fan with large air volume instead of SF type axial fan. This is in terms of appearance and safety.
