Before purchasing the Laser marking smoke purifier, you must understand the characteristics of the processing environment and the amount of smoke and dust: before purchasing the laser marking smoke purifier, you must figure out the smoke concentration generated during work, the average daily working time, etc., which is conducive to choosing the corresponding model of Smoke and dust purifier, thus saving the time of using the filter element of the vacuum cleaner!

At present, there are mainly physical filtration, chemical decomposition filtration, ion treatment, and electrostatic adsorption. Physical soot purification is the preferred technology, and it is best to use a variety of purification technologies to prevent too fast clogging.

Laser marking smoke purifiers have different purification effects. The Laser soot purifier uses four-layer filter elements. The first layer of primary filter cotton filters large particles of dust, suspended solids, and bacteria and viruses in the air. The HEPA filter element filters more than 70 kinds of pollutants such as bacteria, viruses, fungi, pollen, asbestos, etc. The filtering range is as small as 0.3 microns, and the purification rate of super penetrating particles can reach more than 99%. The three-layer activated carbon filter element effectively filters common toxic and harmful gases such as formaldehyde and benzene. The HEPA four-layer filter element is used for secondary filtration to prevent activated carbon powder from entering the machine with the airflow to ensure clean air.

Laser marking fume purifier filtration (purification rate): Purification rate is the key that each user should consider when choosing a laser fume purifier. In fact, the user pursues a high filtration rate, and there is no problem. It should be determined according to the environment in which it is used , Whether to consider the high filtration rate. For example, an operating room or a specific laboratory in a hospital has very high requirements for air cleanliness. At this time, the highest filtration rate must be considered. On the contrary, the working conditions of laser cutting processing do not have high requirements for air cleanliness. The cleanliness requirements will be very high, and the cleanliness requirements of the air will be very high.

When choosing a laser fume purifier, users should consider three aspects:

Can it withstand the noise brought by the maximum air volume; whether the sleep mode can really reach the silent mode; whether the noise is acceptable. Some laser soot purifiers, coupled with cotton mute technology, use DC brushless ultra-quiet motors, which can effectively reduce noise. The laser fume purifier using these two technologies can be selected first when purchasing. Using electrostatic dust removal and pure negative ion technology, there is no secondary pollution. The laser fume purifier will produce ozone, which is also the secondary pollution of the purifier that people often say. A certain amount of ozone can kill bacteria, viruses, and decompose gaseous pollutants, but excessive ozone can cause harm to the human body, affect the lungs, and cause asthma. In severe cases, it can cause cancer. At present, the technologies with higher safety and better purification effect are HEPA net technology and activated carbon technology. Pure ion technology will produce ozone. When purchasing, you should choose laser soot purifiers with HEPA net filter and activated carbon technology.
