Metal Dust Collector System For Laser Cutting

Metal processing refers to the various methods used to transform raw metal materials into finished products or components. The process involves a wide range of techniques including cutting, shaping, drilling, welding, stamping, forging, and casting, among others. The primary objective of metal processing is to convert raw materials into products with desired shapes, sizes, properties, and functions.

Metal processing can be used to create a wide range of products, including construction materials, automotive components, machinery, and electronic devices. The process can involve the use of various metals, including iron, steel, aluminum, copper, and alloys.

A large amount of dust and fume will be generated in these production processes. If it is not handled in time, it will cause healthy problems to employees and affect work efficiency. Therefore, the dust removal system is a very important equipment for the metal processing industry.

What Kind of Dust is Produced During Cutting Process?

Laser cutting produces different types of dust depending on the material being cut. Some common materials that are often cut using lasers include metals, plastics, and wood.

When laser cutting metals, the primary type of dust produced is metal particulate, which consists of tiny fragments of the metal being cut. This metal particulate can be hazardous to health if inhaled, and it is important to have appropriate ventilation and safety measures in place to protect workers.

When laser cutting plastics, the dust produced can be a combination of fumes and particulate. The fumes can be toxic and can irritate the eyes, nose, and throat. Particulate can also be hazardous if inhaled and can cause respiratory issues.

When laser cutting wood, the dust produced is primarily sawdust, which can be a respiratory irritant. It is also important to note that some types of wood, such as oak or mahogany, can produce carcinogenic dust when cut using lasers.

Overall, it is important to take appropriate safety measures when working with lasers, including using dust removal system, appropriate ventilation and personal protective equipment to reduce the risk of exposure to hazardous dust and fumes.


  • Health problems: The small size of metal cutting dust particles means that they can easily be inhaled into the lungs, leading to respiratory problems. Prolonged exposure to metal dust can cause lung diseases such as silicosis, pneumoconiosis, and chronic bronchitis.
  • Fire and explosion risks: Some metals, such as aluminum and magnesium, are highly combustible, and metal cutting dust from these materials can pose a fire or explosion risk if not properly handled.

Why Laser Dust Collector Is Important For Metal Industry?

Laser cutting produces hazardous dust and fumes that can pose significant health and safety risks to workers if not properly managed. Therefore, laser cutting dust removal is essential to ensure a safe and healthy work environment. Here are some reasons why laser cutting dust removal is important:


  • Worker safety: Laser cutting produces fine particles that can easily become airborne and be inhaled by workers, causing respiratory problems and other health issues. Dust removal systems, such as local exhaust ventilation, help to capture and remove these particles before they can be breathed in by workers.
  • Equipment protection: Laser cutting dust can accumulate on equipment and cause damage, resulting in increased maintenance costs and downtime. Removing the dust can help to extend the life of the equipment and reduce maintenance costs.
  • Product quality: Dust can interfere with the laser cutting process and affect the quality of the final product. Removing the dust can help to ensure that the laser cutting process is consistent and that the finished products meet quality standards.
  • Environmental impact: Laser cutting dust can also have negative environmental impacts if it is not properly managed. Dust removal systems can help to reduce the amount of dust released into the environment and minimize the risk of contamination.
    Overall, laser cutting dust removal is critical to ensure the safety and health of workers, protect equipment, maintain product quality, and minimize environmental impact.

Dust Collector System For Laser & Plasma Cutting

1.Dust and Fume Remove Solution

Equipped with PEKAVAC DJS series filter cartridge type automatic pulse industrial dust collector is the best choice for laser cutting machine dust removal. When the laser cutting machine cuts various plates, it will produce a lot of smoke invisible to the naked eye. If it is not cleaned up in time, it will affect the health of the production workers in the workshop.

Different laser cutting machines adopt different dust removal pipe installation methods. 

Single-table and semi-enclosed laser cutting machines will be installed in the way of lower dust exhaust.
For fully enclosed laser cutting machines, we usually use the installation method of upper suction and lower suction pipes.

If you are not sure what model your laser cutting machine is, you can tell us your laser cutting machine model or take a photo directly to help you judge.

2.Piping Design Solution

Some general guidelines can be followed when designing an industrial dust collector pipeline scheme:

  1. Air volume required: The air volume required for the dust collection system should be calculated based on the type and amount of dust produced by the equipment. This will determine the size of the dust collector and the diameter of the pipeline needed to handle the airflow.
  2. Determine the required velocity: The velocity of the air flowing through the pipeline should be sufficient to carry the dust particles without allowing them to settle. A velocity of 4000-4500 feet per minute is recommended.
  3. Plan the layout: The layout of the pipeline should be designed to minimize the number of bends and turns, as this can cause turbulence and reduce the efficiency of the system. The pipeline should also be kept as short as possible to minimize pressure drop.
  4. Choose the right material: The material used for the pipeline should be chosen based on the type of dust being handled. For example, if the dust is abrasive, a harder material such as stainless steel may be required.
  5. Include necessary components: The pipeline should include necessary components such as blast gates, elbows, and transitions, as well as a dust collector and filter. These components should be selected based on the requirements of the system.
  6. Consider safety and maintenance: The design should include safety features such as explosion vents and fire suppression systems, as well as easy access for maintenance and cleaning.
    Overall, an effective industrial dust collector pipeline scheme should be designed to handle the airflow and velocity required to capture and remove the dust particles efficiently, while also considering safety and maintenance requirements.
