Extraction and Filtration Technology for Dust and Smoke ULT UMWELT- LUFTTECHNIK Extraction. Filtration. Persistence.

Many production processes release dust and smoke. In most cases, functional extraction and filtration technology is required.

When handling powdery materials during production processes, e.g. during grinding or filling, dust will inevitably be released. The same applies, when wood, stone or metal material get sawn, milled or abraded. In addition, often smoke and gases are released. Modern techniques, such as rapid prototyping by laser sintering, release blends of extra fine air pollutants. Dust and Smoke Dust can cause respiratory and eye disease. The finer its granularity, the more harmful are its effects, as those particles can overcome the lung-blood barrier and penetrate into pulmonary alveoli. Therefore,...

Dust and Smoke do not equal Dust and Smoke. Two Filtration Systems. Saturation Filter Units With operating processes, extraction precedes filtration. When selecting extraction and filtration technology, however, the reverse order applies. The first question calls for an adequate filtration system. ASD systems offer users the choice between two alternatives. Saturation filter units are primarily used, where the amount of dust and fume is comparably small, for removal of sticky contaminants and for odorous emissions. Dusts and gaseous pollutants are retained by the filtration systems; the...

Cartridge filter units are mainly used to remove dry, intensive dust and smoke in rather high volumes. They feature long service life and low operating costs. Pollutants are collected on the surface of the filter cartridge. The filter cartridge is de-dustible. At intervals, the cartridge gets cleaned with compressed air counter-flush and the dust is completely gathered in dust collectors. Purified air is fed back into the work area.

Type and volume of dust and smoke are not the sole criterion when selecting the adequate filter system. The required extraction capacity is also of key importance. Work place and suction environment are essential here: Saturation filter units ASD How close can I get to the point of pollution generation? What volume capacity shall be extracted? How far must the exhaust air be transported? ASD saturation filter units are primarily designed for low to medium dust and smoke intensity. They are suitable for numerous single-user workstations in labs, manufacturing or industry. The normally small...

Cartridge filter units ASD Vacuum Nominal For high dust and smoke intensity, ASD cartridge filter units are the devices of choice. Due to integrated dust collectors they require slightly more space than saturation filter units. The highest-performing units are stationary devices. They are perfectly suited for extraction at large or central systems and efficiently remove high volumes of dust and smoke. Examples for cartridge filter systems: ASD 300 (left), ASD 300 Ex (middle) and ASD 500 (right)

Critical: Proximity, Geometry Quality of pollutant collection is the linchpin of extraction and filtration technology. In particular, closest proximity to the source of pollution is of critical importance: Doubling the distance, for example means a fourfold increase in required suction capacity and an exponential increase in energy consumption, to collect the corresponding amount of particles. In general, the type of capturing element used must best suit the selective extraction situation at each respective work place. This is a question of both geometry and dimensions. emission...

Individual Capturing Elements ULT selects the type of capturing element that best suits the selective extraction situation at the respective work place from the portfolios of leading suppliers. Often, the design will be adapted, to come to grips with the discharge impulse of pollution particles. Adaptations cover a variety of solutions, ranging from extraction tips and hoods to complete housing of the source of pollution. Naturally, total solutions include suitable extraction arms.
