Oil Mist, Oil Smoke

Oil mist eliminator, oil mist filter

At high manufacturing- and processing-speeds in the metalworking industry, the cooling and lubrication of the workpiece or the tool, as well as the removal of the metal cutting is urgent necessary. Not only specially developed emulsions, cooling lubricants, but also oils are used. Reasons for the formation of the oil mist are the rapid rotational movements during the machining process, which causes the oil to be thrown in the work space. Thus, fine oil droplets form which connect with the ambient air. (Under certain circumstances even an ignitable oil-air mixture can arise!) The workpiece is subjected to high thermal stresses during the machining process. The cooling of the workpiece evaporates the oil to oil steam or oil mist, and at the same time burns a small amount of oil and creates additional oil smoke. If the oil mist reaches the atmosphere of the halls, an oil film will accumulate over the entire inventory over time.

In the case of oil steam or oil vapoure, the particle size is less than 1 μm, and can be inhaled but not coughed out. These particles settled in the leukocytes and thus present an increased risk of cancer. The oil smoke is an additional odor. E-filters can help in this area. Electrostatic filters or electrostatic oil mist separators can filter out up to 99% of the oil particles. Electrostatic air filters are particularly suitable for depositing very small particles (deposition up to 0.01 μm) and provide a separation efficiency of up to 99%. The filters suitable for this purpose are the filters of the elstar series.

Emulsion Mist

Emulsions Mist Collector - Cooling Lubricant Mist Separator

Emulsion is a mixed liquid, without visible demixing, of at least two immiscible components. Emulsions are used not only in the pharmaceutical industry (creams, ointments, etc.) but also in the metal processing industry. Since metal processing is usually carried out at a high process speed, it is necessary to cool and lubricate the workpiece and the tool as well as to transport out the metal cuttings.

Emulsions specially developed for the respective material are used. This emulsion is also called as cooling lubricants or coolant. These coolant fluids are very highly turbulent by the rapid processing process and partly burned by the high temperatures.

This results in the dangerous, negligible cooling lubricant fog or emulsion mist. This fine mist, droplet size smaller than 2.5μm to 2.0μm, is deposited in the processing hall, contaminates your further plants and generates increased fire risk. Much more dangerous are the health hazards:

- increased risk of skidding

- irritation of mucous membranes, skin and eyes

- microparticles settled in the pulmonary vesicles and can not be coughed out. (increased risk of cancer, see VDMA cooling lubricants)

Remedy is provided by an emulsion mist collector or a cooling lubricant mist separator. Electrostatic air filters are particularly suitable for depositing very small particles (deposition up to 0.01 μm) and provide a separation efficiency of up to 99%. Emulsions mist can be filtered out of the air with our elstar or mestar devices. For optimum operation and to extend the cleaning interval at coolant cleaning, we recommend the use of a pre-separator. The coolant filtered from the air can be traced back to the processing process. In general, the contaminated coolant is reprocessed using a suitable filter system. For further information about the wet filtration please refer to the filter fleeceor wet filtration section of our website. An optimally cleaned coolant not only reduces tool wear, but also improves workpiece surface quality

Minimal Lubrication

For the minimum lubrication, only small quantities of cooling lubricants are used.

The oil-air mixture is intended to prevent or reduce the heat of friction by means of an optimal lubrication. The main heat is to be dissipated via the tool and the metal cuttings. The coolant must be properly dosed and fed into the correct location in the cutting process. If less than 20 ml of cooling lubricant is used during a machining process, the term "minimum lubrication" is used.

Advantages of the MMS is the low disposal load, the high service life and the dry metal cuttings can be further processed as a recycling material in contrast to the wet processing. The aerosol vapors arising during minimum lubrication must be filtered accordingly.

Our elstar and mestar models are particularly suitable for this purpose.

Soldering Smoke and Soldering Fume

Soldering Smoke and Soldering Fumes

The material bonding of materials is called soldering. Soldering is differentiated in soft-soldering and hard-soldering or brazing. In soft-soldering, solders are used with a melting temperature below 450 ° C. and during brazing above 450 ° C.

Irrespective of the soldering process or the temperature range, soldering solder or brazed steam is produced during soldering. Depending on the flux or solder material used, these fumes can be very toxic. The components emanating from the solder are usually decomposed with lead, cadmium or other heavy metals. In the flux rosin is used, which completely burns according to the temperature. All these substances make the soldering dust particularly harmful to health.

Furthermore, fine and very fine dusts occur during soldering, which after the inhalation settle in the pulmonary vesicles and can thus pass directly into the blood circulation.

The direct handling of soldering smoke and soldering steam represents an increased health burden for the human eye, skin, lung and airways.

Proper suction is therefore essential for brazing without endangering the environment and health.

Electrostatic air filters are particularly suitable for depositing very small particles (deposition up to 0.01 μm) and provide a separation efficiency of up to 99%. The functional principle is described on the bottom electrostatic air filter principle.

To filter soldering fumes and soldering fumes, use our elstar filters.

Welding- and Laser Smoke

Welding Smoke Separator, Welding Smoke Filter

Laser smoke is generated during laser metal processing such as laser cutting, laser punching, laser welding or laser engraving. The main components of the laser and welding fumes are CO / CO2, ozone and vaporized metal in the electric arc. Microparticles are released to ambient air, which, depending on the quantity and metal material, present different health hazards.

The contact with welding smoke or laser smoke is to be avoided and a suction of the working place is absolutely necessary. Electrostatic filters or electrostatic separators can filter up to 99% of the particles.

Electrostatic air filters are ideal for depositing very small particles (deposition up to 0.01 μm) and thus provide a separation efficiency of up to 99%.

The corresponding dust filters of the duster series are the right choice for air purification.

Metal, Glas and Ceramic Dust

Inorganic dusts can cause severe pulmonary disease. Which disease depends on the mobility of the dust particles.

Dust inhalation diseases are often caused by work and are directly related to daily work or work processes. Often the consequences of lung fibrosis only occur after many years. It is therefore important to detect and filter the dust at the point of origin or exit point.

The legal regulations and the associated air purification for employee protection are therefore indispensable. In order to obtain a maximum cleaned air, our filters can be optimally adapted to your polluted air.

Various pre- and post-filters allow a flexible removal of the filter. Automatic cleaning mechanisms and well thoughtful collecting containers allow for almost contactless disposal of the dust waste.

The devices of the dustar series are the right choice
