Transport fans - Import export

A fan designed for material transport is often a centrifugal fan with an impeller adapted for abrasive particles in the air flow. Fans that transport different materials in the air flow are often extra robust fans, with the right material in the cover and fan wheel. Depending on the application, the fan wheels can be equipped with knives that not only beat but also cut the transported material into smaller pieces, this type of fan is called a knife fan. By developing a fan for your particular application, we ensure that the fan can perform over time – regardless of how tough the application is. With a durable design with a stable fan curve, we know that our fans for material transport can help you with your particular application. Our many years of experience and large product range give our customers peace of mind. Development, design and manufacture of fans takes place with the highest precision and with the highest quality materials.

A flue gas fan is a fan that usually has the task of extracting flue gases from an industrial application, e.g. a melting furnace or pan. Flue gas fans are almost exclusively radial fans and transport not only clean air but also flue gases up to 550° C continuously. Flue gas fans are often a very important component in an industrial system. Our many years of experience and large product range give our customers peace of mind. Development. design and manufacture of fans for flue gas takes place with the highest precision and with the highest quality materials. In order to choose the right flue gas fan, one should start from operating data and system design, as well as whether there are any special requirements.

For the transport of large solid particles with the conveying stream. Transport fans Fans can also be used for the transport of materials. A suitable blade shape and the employment of open impellers enable the transport of large solid particles with the conveying stream. Thanks to our large selection of impellers we can ensure the trouble-free flow of material. Apart from the wood industry, our clientele includes the plastics and paper industries.

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.
