It can be said that the use of smoke exhaust hood in Jinan is becoming more and more common. Exhaust fan, namely exhaust fan, is an air conditioning electric white device, which is driven and rotated by motor to drive air flow, so as to exchange indoor and outdoor air. Also called a ventilator. The purpose of ventilation is to remove indoor dirty air and adjust temperature, humidity and sensory effect. Exhaust fans are widely used in homes and public places.

排氣扇也可稱為排氣扇、排氣扇、換氣扇等。但是產品還是一樣的，這一點大家肯定都知道。但是排氣扇的規格有146*146*95cm，138*138*40cm等。大風量達到8000m3/h。

Exhaust fan can also be called exhaust fan, exhaust fan, ventilation fan, etc. But the products are still the same, which everyone must know. However, the specifications of exhaust fan include 146 * 146 * 95cm, 138 * 138 * 40cm, etc. Until the large air volume reaches 8000m3 / h.

排氣扇采用壓鑄鋁合金外殼的專用電機，防護等級達到高等級IP12。電機可不間斷連續使用2400小時。外殼采用玻璃鋼(玻璃鋼)，輕質、絕緣、防銹、耐老化、防潮、防酸堿、堅固耐用，使用壽命長。

The exhaust fan adopts a special motor with die-casting aluminum alloy shell, and the protection grade reaches the high grade ip12. The motor can be used continuously for 2400 hours. The shell is made of glass fiber reinforced plastics (FRP), which is light, insulated, rust resistant, aging resistant, moisture-proof, acid-base resistant, durable and long service life.

采用獨特的流道技術，外觀防水防雨。采用特殊電機，直接結構免維護(改變傳統皮帶傳動)，提高功能，簡化結構，降低維護成本。空氣順流的原理，百葉窗，無功耗，無開關，能有用防止雨水入侵。計劃安裝不占空間，不需要風管，可以安裝在任何地方。

The unique runner technology is adopted, and the appearance is waterproof and rainproof. The special motor is adopted, the direct structure is maintenance free (changing the traditional belt drive), the function is improved, the structure is simplified and the maintenance cost is reduced. The principle of air downstream, louvers, no power consumption, no switch, can effectively prevent rainwater intrusion. The planned installation does not occupy space and does not need air duct. It can be installed anywhere.

通風換氣方面：安裝在車間窗戶外，一般選擇在百葉負壓風機外排風，提取異味和熱空氣;一般工廠等應用比較多。

Ventilation: it is installed outside the workshop window. Generally, it is selected to exhaust outside the louver negative pressure fan to extract peculiar smell and hot air; Generally, there are many applications in factories.

排風罩是目前國內外廣泛使用的一種通風設備，功能齊全，保護嚴密。它不僅為操作人員提供全方面的保護，還能承受各種化學酸、堿和有 機試劑的腐蝕，不污染內部實驗樣品。保障有毒有害和有氣味氣體的順利排放，使實驗環境達到標準規定的安 果。適用于空調廠、超凈廠的新工藝設備，也廣泛應用于電子、化工、機械、醫藥等行業，以及高校文物保護和實驗室。

Exhaust hood is a kind of ventilation equipment widely used at home and abroad, with complete functions and tight protection. It not only provides all-round protection for operators, but also can withstand the corrosion of various chemical acids, alkalis and organic reagents without polluting internal experimental samples. Ensure the smooth discharge of toxic, harmful and odorous gases, and make the experimental environment reach the safety effect specified in the national standard. It is suitable for new process equipment in air conditioning plants and ultra clean plants. It is also widely used in electronics, chemical industry, machinery, medicine and other industries, as well as cultural relics protection centers and laboratories in Colleges and universities.

總而言之，濟南排煙罩對于我們的飲食環境甚是家庭環境，都起到了關重要的作用，希望大家在日常生活和使用中多加注意維護和清理。

In short, Jinan smoke hood has played a vital role in our eating environment and even our family environment. I hope you will pay more attention to maintenance and cleaning in your daily life and use.
