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.

The term inline filter refers to an expandable, bolted, modular system. Depending on requirements, appropriate filter and air injection sections are connected together in series. The capacity range extends from approx. 10,000–300,000 m³/h. RS / RX filter The RS / RX series are a proven, expandable, modular system with low-pressure purge-air cleaning. Depending on requirements, appropriate filter and air injection sections are connected together in series. The capacity range extends from approx. 20,000–300,000 m³/h. RS / RX filters are suitable only for vacuum and positive pressure operation. The housing parts are usually made of 2 mm thick galvanised sheet steel. A thicker material in a painted execution as well as in stainless steel is also optionally available. The RS / RX series is 2.85 m wide. Filter hose lengths of 3 m (standard) and 4 m are available for this. The RSEC series has been designed for smaller air quantities and for above-roof installation. This series has a housing width of 2.4 m and 2 m-long filter hoses. The filter hoses are manufactured from polyester needle felt; the filtering direction is from the outside inwards. Filter cartridges and filter tubes are alternatively possible. The filter hoses are cleaned off using the material-preserving low-pressure purge-air system. The purging trolley inside the clean air compartment drives over the hose openings either continuously or controlled by pressure. In the direction of movement the first filter hose row is neutralised, while the second row is flushed from the clean air side. The third row is likewise neutralised. This results in a draught delay, which is necessary in order to allow the dislodged dust to fall into the discharge. The dust is discharged by a tried-and-tested drag conveyor with a downstream cellular wheel sluice. The return air pipes are provided with fire protection flaps and switching devices for exhaust air operation. The filter housing has been tested for resistance to pressure surges. Standard safety devices include likewise tested explosion pressure relief devices, fire extinguishing systems, mechanical and thermal monitoring systems as well as pressure-surge-resistant and flameproof cellular wheel sluices. The transport fan is arranged on the clean air side and is not exposed to swarf and dust. Hence, the conditions of a dust explosion zone do not prevail in the transport fan. RSV/RXV filter This series essentially differs from the RS/RX series in that its fans are arranged on the clean air side. RSV/RXV filters are suitable only for vacuum pressure operation. The capacity range extends from approx. 20,000 - 300,000 m³/h. The filter hoses are likewise cleaned off using the material-preserving low-pressure purge-air system.

A bio scrubber combines physical scrubbers with a biological activation unit. In this process, air polluted with a wide variety of pollutants is cleaned with the aid of a washing liquid which is loaded with microorganisms and biocatalysts (various enzymes) taken from nature. The washing water absorbs the exhaust air and pollutants from the air. Subsequently, added microorganisms oxidise them. These microorganisms use the air pollutants as substrate and nutrient medium and convert them into naturally formed decomposition products such as CO2, water, and biomass. Here, the washing water is continuously regenerated and used in a closedcircuit water treatment system. TYPICAL APPLICATION AREAS These plants are primarily used for watersoluble ingredients of the exhaust air. The usual pollutants that are filtered from the exhaust air with the help of bio scrubbers include aldehydes such as formaldehyde, alcohols, ketones and other hydrocarbon compounds.

When it comes to filter material, there are a few points to consider. The filter material should have a large surface area. This ensures a good exchange rate between exhaust air and filter material and provides sufficient space for microorganisms to colonise. The filter material must be designed in such a way that it has a good water holding capacity. The colonised microorganisms are only viable in a moist environment. In general, different filter materials are used in one batch. The reason for this it ensures both a good stability of the filter bed and a larger surface. In addition, the added microorganisms must be sufficiently supplied with inorganic nutrients and trace elements, unless this is provided by the composition of the exhaust air. The temperature inside the biofilter system plays a decisive role as well. Temperatures between 5 °C and 40 °C are favourable for the microorganisms to work properly.

The compact electrode housings of our treatment stations are used for the reliable extraction of the ozone created by the corona treatment. Exhaust monitoring is an integral part of all corona stations and ensures that a corona discharge can not be activated without suction. The ozone is extracted by a pipe work and discharged to a safe height into the external atmosphere. To reduce the ozone load of the ambient air and comply with local environmental and health and safety regulations the extracted air can be passed directly into an ozone catalyser. Our ozone catalyser is a high performance filter unit designed specifically for ozone destruction in Corona treatment. Since ozone is extremely corrosive, all materials and seals used are corrosion resistant. The housing and all internals are made from corrosion resistant stainless steel. For reliable treatment of the exhaust air, three filter stages are contained within the housing.

100 - 3600 CFM / 170 to 6,100 m³/h The NASH SC vacuum pump and compressor, which replaced the popular NASH CL pump in the 1980's, is still being manufactured at Gardner Denver Nash.
