1、根据应用需求，考虑是否需要连续工作，要充分考虑电源系统、整体性能等方面需求。
1. According to the application requirements, it is necessary to consider whether continuous operation is needed, and the requirements of power supply system and overall performance should be fully considered.
2、根据灰尘具体情况来选择干式还是干湿两用型，再根据灰尘浓度来选择功率大小。
2. According to the specific situation of the dust to choose dry or wet dual-purpose type, and then according to the dust concentration to choose the power size.
3、考虑产品质量和性能，如吸力、工作时间、功能、结构设计、外观、操作、保养等多个指标。吸力足够大，以满足应用需求，而工作时间能够可连续24小时工作，功能以丰富但不会带来操作麻烦为宜。
3. Consider product quality and performance, such as suction, working time, function, structural design, appearance, operation, maintenance and other indicators. The suction force is large enough to meet the application requirements, and the working time can work continuously for 24 hours. It is appropriate to have rich functions but not cause operation trouble.
4、根据预算和应用需求来选择进口产品还是国产产品。一般来说，国产品牌价格低但质量上很难保障，而进口品牌质量高，但价格却偏贵。

4. According to the budget and application demand, we can choose the imported product or the domestic product. Generally speaking, the domestic brand price is low, but the quality is difficult to guarantee, while the imported brand quality is high, but the price is relatively expensive.
5、考虑供货商是否有代理商的授权资质等。
5. Consider whether the supplier has the authorized qualification of the agent.
6、考虑服务，包括售前、售中和售后服务，尤其是看能否提供专业、持久的售后服务。
6. Consider service, including pre-sale, sales and after-sales service, especially to see whether professional and lasting after-sales service can be provided.
工业吸尘器能够吸取各类金属、非金属、油、水等颗粒污物及液体，能够吸收有毒有害气体，在纺织行业中可以提高产品的质量，在化工行业可以回收一些昂贵的催化物等，而且做为一种环保设备，工业吸尘器可以有效防止一些职业病的危害，如电焊工尘肺等。  工业吸尘器龙谷高压风机同家用吸尘器相比，工业吸尘器具有可连续24小时使用，吸力强劲、储尘容积大、使用寿命长、可耐高温等优点，特别是工业吸尘器对吸取物几乎无要求，各类材质、各种形状的废弃介质物都可以吸取，通过对过滤介质，如滤芯、滤袋等的调整，可以吸收达0.1微米精度的固体颗粒物，可适用于精细化工、精密机械等行业。
Industrial vacuum cleaner can absorb all kinds of metal, non-metal, oil, water and other particulate dirt and liquid, can absorb toxic and harmful gases, can improve the quality of products in the textile industry, in the chemical industry can recover some expensive catalyst, and as an environmental protection equipment, industrial vacuum cleaner can effectively prevent some occupational diseases, such as welder's pneumoconiosis. Compared with the household vacuum cleaner, the industrial vacuum cleaner Longgu high-pressure fan has the advantages of continuous 24-hour use, strong suction, large dust storage capacity, long service life, and high-temperature resistance. In particular, the industrial vacuum cleaner has almost no requirements on the absorbed materials, and all kinds of waste media of various materials and shapes can be absorbed Adjustment, can absorb 0.1 micron precision solid particles, can be used in fine chemical industry, precision machinery and other industries.
