The gas collection (smoke) hood is generally processed as a whole, including equipment such as filtering, oil collection, and water collection, and is mostly produced by professional kitchen companies. Its appearance should be uniform, beautiful, and easy to clean. In kitchen ventilation, a certain amount of fresh air needs to be added. On the one hand, it can balance the air pressure and avoid excessive negative pressure in the kitchen (generally not exceeding 5Pa), and on the other hand, it can reduce the temperature inside the kitchen and improve the working environment. For the collection of cooking fumes, there are three main categories of gas collection (smoke) hoods used:

簡易不含擋油板和送風設備的集氣罩適合各種靈活機動場所，便于加工安裝，便宜。但由于沒有送風設備，集風效果相對較差，容易使油煙在廚房工作人員面前回旋，并且容易造成油滴散落。

The simple gas collection hood without oil baffles and air supply equipment is suitable for various flexible and mobile places, easy to process and install, and cheap in price. However, due to the lack of air supply equipment, the air collection effect is relatively poor, which can easily cause oil fumes to swirl in front of kitchen staff and cause oil droplets to scatter.

含擋油板和送風設備的集氣罩能夠較好地收集烹飪過程產生的油煙，油滴不散落，只要送風風量合理，廚房操作人員工作面的空氣質量就好。但安裝要求較高，投資較大。

The gas collection hood with oil baffle and air supply equipment can effectively collect oil fumes generated during the cooking process, and oil droplets do not scatter. As long as the air supply volume is reasonable, the air quality of the kitchen operator's working face is good. But the installation requirements are high and the investment is large.

運水集氣（煙）罩的設計原理是形成水幕循環，與油煙碰撞后達到凈化油煙的目的。影響運水集氣（煙）罩使用效果的關鍵是要形成連續的水幕，并需要對循環水系統進行定期清理。實際上由于管理不善，目前大部分運水集氣（煙）罩無法形成連續水幕，而只是形成了斷續流動的水滴或小水柱，因此使用效果非常差。

The design principle of the water transportation and gas collection (smoke) hood is to form a water curtain circulation, which collides with the oil smoke to achieve the purpose of purifying the oil smoke. The key to affecting the effectiveness of the water transportation and gas collection (smoke) hood is to form a continuous water curtain and regularly clean the circulating water system. In fact, due to poor management, most water and gas (smoke) hoods currently cannot form a continuous water curtain, but only form intermittent flowing water droplets or small water columns, resulting in very poor performance.
