We design, project, manufacture and implement industrial dust extraction systems. Application of our exhausting products in various industries.

Welding smoke extraction

Solution of the welding smoke extraction

Our filter units are suitable for extracting smoke, dust, fumes and aerosols generated during metal welding. The extraction of the welding process is very important to ensure a clean working environment inside the work hall.
Recycling operations extraction

Solution of the recycling operations extraction

Material recycling is a waste management process that leads to its reuse. In the recycling process, the input material is always technologically divided into unusable waste and output raw material, which is used for subsequent cyclic processing. A large amount of dust accompanies practically the entire recycling process, from the receipt of material to the packaging output product.
Textile dust extraction

Solution of the textile dust extraction

We sort textile dust, respectively textile fibers, for vegetable fibers, animal fibers and inorganic fibers. Textile dust is created during the production of any fabric. Production processes in textile industry we can divided into two main groups: mechanical operations (spinning, weaving, knitting) and finishing (wet processing, where the main useful properties are added to textiles).
Laser and plasma extraction

Solution of the laser and plasma extraction

We ensure extraction and filtration of harmful substances by extracting fumes during machining of the material by laser or plasma in the form of fumes and exhaust gases, that are released during the cutting of the material. Exhaust system is connected to extracting table and ensures extraction of exhaust gases from below. During laser and plasma extracting, dust particles, particles of divided material and sparks are also part of the extracted fumes.
Extraction during cutting aluminum

Solution of the extraction during cutting aluminum

During cutting aluminum with saw blades a large amount of aluminum sawdust is produced. The volume of aluminum sawdust for powerful automatic cutting machines is so large, that it is impossible to remove sawdust from machine manually and their removing is solved using exhaust system. The exhaust system ensures constant draft in the extraction pipe so that aluminum sawdust doesn’t settle inside the machine and in the extraction pipe.
Aluminum dust extraction

Solution of the aluminum dust extraction

The aluminum dust generated during grinding or polishing of aluminum profiles created together with air a highly explosive mixture. The aluminum dust is dangerous not only in the air, but also in the deposits of this dust in the machine space or in the grinding machine.
Blasting booths and blasters extraction

Solution of the blasting booths and blasters extraction

We focus on dust extraction in blasting booths and blasters. Dust extraction is an important part of this surface treatment during blasting or sandblasting. Blasting is technological process of surface treatment of various, usually hard, materials by jet pressurized abrasive particles. The most used abrasives are for hard materials steel shot and steel granulate S, silica sand, corundum, ballot paper, steel grit, white cast iron. slag crumb or ceramic microspheres.
Sawdust extraction during woodworking

Solution of the sawdust extraction during woodworking

Sawdust extraction during woodworking is an integral part of production of any wood product. During processing raw wood are sawdust wet and heavy and the method of their extraction and subsequent processing is different from the dry sawdust extraction. We often use small mobile sawdust extractors to single-purpose woodworking machines and also central sawdust extraction systems in wood production halls. Subsequent processing of sawdust has a constantly higher priority.
Dust extraction from metallization of products

Solution of the dust extraction from metallization of products

The metallization means applying a layer of molten metal to the surface of the metallized product. Metallization is used as a surface protection of the product or its components, where increased chemical resistance of the base material to corrosion is required. Metallization is used not only for metal surfaces, but also for non-metallic products, as wood, rubber, and leather.
Extraction of melting furnaces and cupolas

Solution of the extraction of melting furnaces and cupolas

Flue gas extraction from melting furnaces is one of the most important extraction systems in foundries, smelters, and ironworks. During metal melting a large amount of flue gas, which must be extracted with a performance-stable extraction and filtration system, is created. Flue gas extraction from melting furnaces is divided into hot and cold applications according to the temperature of the flue gas extracted. Hot flue gases are created in gas melting furnaces, cupolas, and rotary kilns. The temperature at the outlet of the furnace is around 350 to 500 °C.
Extraction during grinding and polishing

Solution of the extraction during grinding and polishing

Abrasive dust extraction is one of the most common applications of air extraction and filtration systems. Product grinding is a part of most production, not only in mechanical engineering. In mechanical engineering and automotive, we most often apply the extraction of grinding mills for metal products, when welds are ground before painting. Grinding does not have to be just a dry process, where we extract dry dust particles, but grinding with cooling emulsion is often used in CNC machining.
Extraction in the food industry

Solution of the extraction in the food industry

High-performance extraction in food operations is very important to ensure a clean working environment. The dust is freely spread into the space of production lines can be a source of impurities and bacteria, which are in food production completely undesirable. Food dust deposits in the corners of the production line can create an explosive environment, which means danger for production workers. Main applications of food operations extraction are sugar dust extraction, flour dust extraction, extraction in the production of spices, and extraction of product packages. The most common application of food operations extraction is the extraction of material weighing points and mixture hoppers.
Dust extraction in the quarry

Solution of the dust extraction in the quarry

Dust extraction in the quarry ensures the protection of the environment by dust extraction, but mainly ensures the cleaning of individual fractions of crushed stone from dust particles. The previously used pressurized water mist is a system effective in reducing the spread of dust to the environment, but the dust associated with the water mist ends up back in the gravel. Recipients of gravel fractions today control, among other things, the amount of residual dust - filler - in the purchased gravel fraction, which increases the requirements for dry dust extraction.
Extraction of vibrating grinders during cement grinding

Solution of the extraction of vibrating grinders during cement grinding

We produce high-pressure filter units for extraction of vibrating grinders during cement grinding. Extraction of vibrating grinders consists of connecting a high-pressure exhaust hose directly to the nozzle of the vibrating grinder. The cement extraction takes place through abrasive sandpaper, which is from the manufacturer equipped with suction holes. In high-pressure extraction of the cement directly from the grinder, the sanded dust is not spread into the grinding booth space, but the dust is exhaust directly into the high-pressure filter unit.
Extraction walls for wet and powder coating

Solution of the extraction walls for wet and powder coating

Paint extraction walls are an integral part of wet and powder paint shops. They ensure the extraction of paint splashes and released volatile substances from the paint shop or production hall. Extraction walls are equipped with several stages of filtration.
Extraction of oil mist and aerosols

Solution of the extraction of oil mist and aerosols

Oil mist extraction is an application characteristic of CNC machining using a cooling emulsion. When we are machining with high-speed tools, a large amount of thermal energy is released and for this reason a cooling emulsion is used to cool both the tool and the workpiece. In the CNC machine, the cooling emulsion is sprayed in the form of an aerosol formed by micro-droplets of the cooling emulsion. At the same time, the emulsion evaporates due to high machining temperatures. Evaporation of the emulsion produces oil fumes. In the absence of extraction of the CNC machine, oil emulsions and vapors are spread into the production hall through leaks in the machine cover.
Flue gas filtration of biomass boilers

Solution of the flue gas filtration of biomass boilers

Dedusting and filtration of flue gases from a coal or biomass boiler is a very important topic due to the increasingly stringent requirements for the discharge of solid pollutants into the air. Most of the operated biomass boilers, mostly of older production date, are equipped only with cyclone separators or multicyclones. These flue gas ash capture technologies do not achieve the required separation efficiency and the boilers thus exceed the permitted TZL emissions. Dust removal of flue gases from biomass boilers is specific to the large occurrence of non-burnt in the form of unburned particles of sawdust, bark, or wood chips.
