With the rapid development of the global economy, people’s quality of life has gradually improved, but the resulting environmental problems have become increasingly severe. For example, air quality is the focus of concern for all mankind. PM2.5 (inhalable particulate matter) is one of the culprits of air pollution.

What is PM2.5?

PM2.5 (inhalable particulate matter) refers to particulate matter with a diameter of less than or equal to 2.5 microns in atmospheric particulate matter, usually composed of solid and liquid particles from various sources. The main components of these particulate matter include:

  • Automobile exhaust: including particulate matter produced by fuel combustion, such as carbon, sulfur, and nitrogen oxides;
  • Industrial emissions: particulate matter produced in various industrial production processes, including metals, chemicals, smoke, etc.;
  • Wood and biomass combustion: particulate matter produced by home heating, wild fires, etc.;
  • Construction and road dust: particulate matter produced by construction sites, road construction and transportation;
  • Atmospheric reactions: PM2.5 can also include chemical reaction products in the atmosphere, such as nitrates, sulfates, etc.

What are the hazards of Pm2.5?

PM2.5 particles are dangerous because they are small enough to penetrate deep into our respiratory tract, including the nasal cavity, throat, bronchi and lungs. This tiny size allows them to bypass the defenses of nasal hair and mucous membranes and enter our respiratory system directly. Long-term exposure to PM2.5 can cause a series of respiratory problems, including asthma, bronchitis and lung cancer.

In addition to the threat to the respiratory system, PM2.5 also poses a significant risk to the cardiovascular system. These tiny particles can enter our blood circulation and cause diseases such as heart attacks, strokes and high blood pressure. They can induce thrombosis, lead to vascular stenosis, and ultimately cause cardiovascular problems.

The necessity of industrial fume extractor?

At present, in industrial fields such as engineering machinery, shipyards, mining equipment, heavy machinery, bridge manufacturing, metallurgical equipment, rail transportation, nuclear power and other industries, manual CO2 gas shielded welding and manual arc welding are still the main methods. The welding, cutting and grinding processes in the production process will produce dusty exhaust gas.

Workers working in a fume-filled environment have a huge impact on their health. If welding fumes are inhaled for a long time, it will cause dizziness, headache, cough, chest tightness and shortness of breath, and induce complications such as welder pneumoconiosis, manganese poisoning, fluorine poisoning, metal fume fever, pneumonia and blood system diseases. This is a potential huge risk for enterprises and employees. Appropriate industrial fume extraction measures must be taken to minimize the harm of PM2.5 to the environment and human body.

Industrial fume filtration solution

The welding fume particles are small in size and in fragments with a particle size of 0.01-10μm, of which most of the fume particles are distributed around 0.38μm. The amount of dust generated during the welding process is large. Generally speaking, the amount of fume generated by a welder in one day is about 60~150g. And these particle sizes of fume are also the easiest to enter the worker’s respiratory system and dissolve in the blood, which is extremely harmful to the worker’s health. Therefore, the filtration efficiency of industrial dust collectors is extremely high.

The welding fume extractor produced by Mengfei Filtration has brought the most effective and affordable industrial fume filtration solutions to many business owners. This welding fume purifier adopts high-precision and high-efficiency filter membrane materials, which can effectively clean the welding fume in the working area. It is easy to move and suitable for a variety of working environments. It can automatically clean the dust through microcomputer control, effectively remove the fume generated during welding, cutting and grinding, and protect the health of workers.
