专注通风管道加工·排烟罩

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.

系列选型按净化风量选择，计算公式：风量=风速*截面积（Q=V*S）。一般我们取以一个炉灶处理4000m3/h风量选择，风量越大净化效果越好。（注：此选择方式为一般情况，若遇川菜湘菜或油烟量大的地方，设应增加净化器的处理风量。）

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系列净化器进风口的位置应安装在距离炉灶8-10m的位置，烟罩出口后面需预留少5米以上，以确保消防和净化效果；净化器与风机的距离在2米以上比较合适。

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.

设备箱体必须接的高空油烟净化器和低空油烟净化器设备选型对比：

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

安装位置不同，低空排放型油烟净化器一般安装在一楼或与厨房同一楼层位置。高空排放型油烟净化器一般安装在距离厨房三楼及以上的位置。

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.

净化级不同，低空排放型油烟净化器属于2级净化。高空排放型油烟净化器属于一级净化。

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，低空油烟净化器设备配置高功率大净化时间长，因此净化效率与出除味效果都很好。4不同，由于净化级的增加低空排放型油烟净化器相对高空排放型油烟净化器高出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.
