The synthesis dust filter bag has been a very high quality option for commercial cleaning for more than 10 years. The non-woven material is very robust, so that e.g. stones, light moisture and fine dust can be absorbed. In addition, dust retention values, separation efficiencies and durability have been improved. For these reasons, the Synthese dust filter bag is also increasingly used for light cleaning jobs. Synthese 3, 4 or 5 ply, filter bags with dirt flap, sliding closure or plastic connection, Synthese dust filter bags also in set with motor protection filter, household filter bags

For the conveying of filtered-out materials to silos or containers. Pneumatic low-pressure conveyor systems For the conveying of filtered-out materials to silos or containers and for conveying distances of up to 200 m. The conveying air stream is generated by one or more fans. Product description Pneumatic low-pressure conveyor systems can be implemented as a single-pipe system or a ring system. In the case of the single-pipe system, a final separator in the form of a filter or a cyclone is always necessary. In a ring system the conveying air is driven in the ring. In this case the silo or container acts as the separator. Light dust particles that are not separated in the silo or container initially remain in the circulation. With most materials the fine dust particles tend to attach themselves to the coarser ones and are thus separated with them. Hence, a concentration of the fine dust particles in the conveying stream is avoided as far as possible. The loading of the conveying stream essentially depends on the grain size, density and form of the material to be conveyed. As a guiding value, one may assume 250 - 300 g/m³. Higher loads are possible under certain conditions. In cases where there is a high amount of material, e.g. in planing works, where the splinters are directly removed and transported away for further use, this can also be realised with a ring system and several containers. Switchover takes place automatically when the container signals that it is full. Containers are exchanged during operation.

Force-of-gravity separators, which are used as pre-filters or for the separation of large quantities of dust and swarf. Cyclone separator Cyclones are force-of-gravity separators. The separation principle is based on centrifugal force, which is produced by the tangential injection of the raw air. Cyclones are used as pre-filters or for the separation of large quantities of dust and swarf. The degree of separation of a cyclone is not normally sufficient to meet the usual environmental protection requirements. The cyclone exhaust air must be post-filtered in most cases. Product description A cyclone essentially consists of three parts: the intake cylinder, the cone and the immersion tube. In the intake cylinder, the raw air is brought into a circular path by means of tangential injection. Due to the taper of the subsequent cone, the speed of rotation increases sharply, so that the particles are pressed by centrifugal force against the outer wall and decelerated by friction, causing them to drop out of the air stream and fall down. The cleaned air leaves the cone in an upward direction via the central immersion tube. Cyclones are usually welded sheet steel structures. Cellular wheel sluices or, in individual cases, double-gate sluices are used for the pressureless discharge of the material. In order to increase the cyclone effect, or the degree of separation, counter-spirals with a pipe connection can be placed on top of the immersion tube. Further options are, for example, wearing devices, explosion pressure relief devices, control flaps, level monitoring devices and manufacturing in stainless steel or galvanised sheet steel.

Type RK/RF for continuous operation, suitable for virtually all types of dust. Round filter type RK / RF The round filters from this series are suitable for continuous operation and for almost all types of dust. What is special about them is the rotary cleaning device, which causes the dust to be sucked out of the filter hoses and discharged. Using other methods the dust is also continuously dislodged from the filter element, but contaminates the other filter elements in the next moment. Only a small part of the dislodged dust falls down and is discharged. The lower part of the filter is implemented like a cyclone and acts as a pre-filter, where coarse dust is already separated and discharged. Compressed air impulse cleaning is also possible as an option here. The filtering direction of the filter hoses is from the outside inwards. The hoses are provided with support frames.

The BIOCATDUOscrubber from WesselUmwelttechnik consists of two units. One unit is the already mentioned BIOCATscrubber. A second unit, the DLP (Dust Low Pressure) scrubber stage, is a cleaning stage for separating dust and fine fibres from the exhaust air. With the BIOCATDUOscrubbers from Wessel, gaseous pollutants as well as dust can be removed from the exhaust air at the same time. The BIOCATDUOscrubbers have two separate washing water circuits for this purpose. It is characterised by a compact design, as both units are housed in one column. COMMON USE CASES The BIOCATDUOscrubbers are used in the woodbased panels industry, for example. More precisely where MDF boards (medium density fibre) and moulded fibre parts are produced. Here the exhaust air contains fine wood fibres which have to be filtered out of the exhaust air. Furthermore, pollutants and odours must also be reduced.

HELIO®Clean 2 is a combined conveying-/ mixing-/ and dedusting device for virgin material and regrind. The dust is removed through a 2-stage dedusting system. The compact design makes it ideal for mounting on the feed zone of the processing machine or on a drying container. The separated dust content is sucked out into an external collection bin. Available in 1- or 2-component version, filling is carried out by the integrated compressed air conveying technology with Venturi suction lance(s). Quality: Dust in granules causes lowered mechanical properties of technical plastic resins, leads to problems with surface finish in case of transparent parts, to high rate of rejects basing on smudges or white/black dots in transparent injection moulding parts like for example optical lenses of PC and PMMA. Professional cleaning of resins brings the quality to the original state again and optically perfect parts can be produced.
