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.

系列選型按凈化風(fēng)量選擇，計算公式：風(fēng)量=風(fēng)速*截面積（Q=V*S）。一般我們?nèi)∫砸粋€爐灶處理4000m3/h風(fēng)量選擇，風(fēng)量越大凈化效果越好。（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(shè)應(yīng)增加凈化器的處理風(fēng)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系列凈化器進風(fēng)口的位置應(yīng)安裝在距離爐灶8-10m的位置，煙罩出口后面需預(yù)留少5米以上，以確保消防和凈化效果；凈化器與風(fēng)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(shè)備箱體必須接的高空油煙凈化器和低空油煙凈化器設(shè)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，低空排放型油煙凈化器一般安裝在一樓或與廚房同一樓層位置。高空排放型油煙凈化器一般安裝在距離廚房三樓及以上的位置。

The installation location 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.

凈化級不同，低空排放型油煙凈化器屬于2級凈化。高空排放型油煙凈化器屬于一級凈化。

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，低空油煙凈化器設(shè)備配置高功率大凈化時間長，因此凈化效率與出除味效果都很好。4不同，由于凈化級的增加低空排放型油煙凈化器相對高空排放型油煙凈化器高出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.
