The series of oil fume purifiers belong to the low altitude emission type and are suitable for installation on the first floor or the same floor as the kitchen.

係列選型按淨化風量選擇，計算公式：風量=風速*截麵積（Q=V*S）。一般麻豆精品国产传媒取以一個爐灶處理4000m3/h風量選擇，風量越大淨化效果越好。（注：此選擇方式為一般情況，若遇川菜湘菜或油煙量大的地方，設應增加淨化器的處理風量。）

The selection of the series is based on the purification air volume, and the calculation formula is: air volume=wind speed * cross-sectional area (Q=V * S). Generally, we choose a stove to handle 4000m3/h of air volume, and the larger the air volume, the better the purification effect. (Note: This selection method is a general situation. If encountering Sichuan cuisine, Hunan cuisine, or places with high oil smoke, the design should increase the processing air volume of the purifier.)

GJ係列淨化器進風口的位置應安裝在距離爐灶8-10m的位置，煙罩出口後麵需預留少5米以上，以確保消防和淨化效果；淨化器與風機的距離在2米以上比較合適。

The position of the air inlet of the GJ series purifier should be installed 8-10m away from the stove, and at least 5 meters should be reserved behind the smoke hood outlet to ensure fire safety and purification effect; A distance of more than 2 meters between the purifier and the fan is more suitable.

設備箱體必須接的高空油煙淨化器和低空油煙淨化器設備選型對比：

Comparison of equipment selection for high-altitude and low-altitude oil fume purifiers that must be securely connected to the equipment box:

安裝位置不同，低空排放型油煙淨化器一般安裝在一樓或與廚房同一樓層位置。高空排放型油煙淨化器一般安裝在距離廚房三樓及以上的位置。

The installation locations is different, and low altitude emission type oil fume purifiers are generally installed on the first floor or the same floor as the kitchen. The high-altitude emission type oil fume purifier is generally installed at a distance of three floors or above from the kitchen.

淨化級不同，低空排放型油煙淨化器屬於2級淨化。高空排放型油煙淨化器屬於一級淨化。

The purification level is different, and the low altitude emission type oil fume purifier belongs to level 2 purification. The high-altitude emission type oil fume purifier belongs to the first level of purification.

配置不同，低空油煙淨化器設備配置高功率大淨化時間長，因此淨化效率與出除味效果都很好。4不同，由於淨化級的增加低空排放型油煙淨化器相對高空排放型油煙淨化器高出2倍左右。

The configuration is different, and the low altitude oil fume purifier equipment is equipped with high power and long purification time, so the purification efficiency and odor removal effect are both very good. 4. The prices are different, due to the increase in purification level, the price of low altitude emission type oil fume purifiers is about twice higher than that of high altitude emission type oil fume purifiers.
