Filtration and Fume Extraction Applications
Laser Processing - Engraving, Cutting, Marking
Lasers can be used to process various materials including metals, woods, plastics, glass, foam, and much more. Due to laser versatility, companies are focusing intensively on utilizing laser technology. Regardless of whether YAG, CO2 or ultrashort pulse lasers are used, they all produce hazardous laser smoke. The health-threatening smoke or laser dust contains pollutants that dissolve from the processed material. Laser smoke can damage lungs as well as the respiratory tract and can be carcinogenic. Lasers Plus offers many solutions for extracting and filtering laser processing byproducts depending upon your unique process and laser configuration.

Soldering - Hand, Wave, Reflow Ovens
In the process of soldering, two different materials are joined together by melting. Fume extraction systems are necessary to extract particles and fumes from solder, flux, chemicals, and gasses ensuring a safer working environment. Soldering fumes contain carcinogenic substances such as cobalt or nickel. Although the toxic heavy metal lead is contained in less fluxes, it is still frequently used, for example, in medical processes. Whether your solder process is hand soldering, solder pots and fountains, wave solder machines, or reflow ovens it is important to equip the proper filtration system to suit your workflow needs and protect employees.

Welding Processes - Automated and Manual
Welding processes release very fine particles from the surface to be filtered. When these dangerous substances break down on the lungs, they can trigger permanent incapacity to work. There must be efficient extraction of welding fumes to prevent this from happening. Welding releases very fine particles, smaller than 1 µm, from the processed surface. The concentration of pollutants generated during the welding processes is carcinogenic and thus hazardous to health. Capturing fumes at the source using an extraction arm and hood is typically best to protect employees during the welding process.

Clean Room Processes
Cleanrooms are microbiologically controlled. They ensure air purification and sterilization and thus protect the health of people working in the food and automotive industries as well as in biotechnology, chemistry, electromechanics, electronics, pharmaceuticals and medicine. TBH filter and extraction systems extract reliably particles and gases directly at the point of origin.

Dusts and Chippings: Grinding, Machining, Drilling
Metal working processes such as milling, turning, drilling, and grinding produce hazardous dusts which are carcinogenic and can potentially trigger dangerous explosions. Dry machining of metals and plastics produce abrasive dusts and fumes that makes extraction essential. Wet machining releases drops of cooling water spray into the ambient air during eroding or electric discharge machining (EDM). Particles from electrically conductive materials such as aluminum or copper as well as oil mist or emulsion mist must be extracted from wet machining processes. Grinding processes also release large amounts of hazardous dusts that need to be removed to protect the workplace.

Gasses / Odors / Vapors: Cleaning, Painting, Restoration
Numerous cleaning processes, painting processes, and restoration projects release gasses and vapors which cause air pollution and health hazards in the workplace. Solvents are also used in analog and manual bonding processes, as well as in cleaning parts. While solvents are barely used in bonding processes anymore, it is indispensable in cleaning injection molds, e.g. for removing incrustations. Outgassing and evaporated particles occur in both processes. The vapors during thermal processing of plastics, i.e. plastic injection molding, must be extracted.

Medicine & Aesthetics - Laser Medical Treatments, Dental
Medical treatments can generate harmful particles and vapors. Patients expect infection protection and cleanliness during all medical procedures. To protect patients and staff members, more and more physicians are using filtering extraction technology during medical and aesthetic procedures, thus keeping the risk of infection to a minimum. For instance, during laser hair removal, highly toxic vapors are produced while burning hair follicles with the laser. Those must be reliably extracted and filtered. In addition to numerous laser skin care treatments and laser eye surgery, many dental practices require filtration for high aerosol concentrations that oral suction does not protect against.

Importance of Fume Extraction and Filtration
During many work processes in industrial, medical, or home operations dangerous particles can be generated in the environment. Many of these pollutants can enter the bloodstream causing medical issues such as lung cancer. Utilizing air filtration is essential to protecting workers, equipment, and the environment.
Pollutants in the air are considered the invisible enemy as they may appear invisible, tasteless, odorless, and untouchable. The human body can survive a maximum of five minutes without air. While eating is a conscious activity, oxygenation is an unconscious process. Think of what goes into your body 12 to 18 times per minute.
Smaller particles have longer settling times allowing them to remain in the environment for an increased duration. It is critical to capture these particles quickly.
It is common to have 3 stages of filtration for various processes: pre-filters are the first line of defense followed by a particle filter and molecular filter. Particles larger than 0.1 μm can be captured with a pre-filter rated M5-F9 or E10-U17; suitable to capture metallurgical dust and oil mist.
Particles that range 0.1 – 0.3 μm require a HEPA particle filter which can capture 99.95% of particles in this size range depending upon the classification of the filter. H14 filters can capture these particles 99.995% of the time.
A molecular filter is required for gas molecules sized less than 0.1 μm and activated carbon is the only filter medium for particles this small. The activated carbon filter can physically absorb these particles trapping them or chemically neutralize them breaking it down through a reaction.
