Industrial Dust Collectors from Höcker Polytechnik
MultiStar filter systems at a glance
Product Description: What Höcker Polytechnik’s Industrial Filter Systems Achieve
Production machines, no matter the industry, generate chips and dust through the material machining process. These need to be efficiently extracted to ensure high-quality production processes. Thanks to the excellent filtration results, usually at 0.1 mg/m³/h, combined with fresh air blending or heating, operators of our filter systems save on heating costs, and there is a pleasant room and work environment.
Höcker Polytechnik filter systems work for you in process waste disposal during production. We keep your production processes clean, ensuring compliance with workplace dust concentration limits.
To achieve this, the processing machines are connected to the extraction systems via precisely dimensioned pipelines, providing the necessary energy and speed for extraction. The extraction fans generate a pre-calculated negative pressure. This ensures the machines are properly extracted and kept free of dust and chips.
Efficient operation of the filter systems is important to us and you. By optimally designing the filter systems in terms of injection, pre-separation, cleaning, and filter media, we can meet this standard. This keeps electrical energy and operational costs very low.

What Höcker Polytechnik's Filter Systems Achieve for Your Industry
The purpose of a filter system is to clean a certain amount of air from production processes involving processing machines, mixed with dust and air, to ensure that predefined limits for dust and pollutants are reliably met. The filtered air can usually be returned as clean, warm air to the production areas. There are several factors to consider here, such as the composition of the dust/air mixture, particle sizes, the filter medium, and the operating mode of the systems.
Suitable for both industrial and craft applications, the dust filters are ideal for industries such as: wood processing and woodworking, plastic processing, paper, printing, and packaging industries, wood industry, furniture industry, and anywhere where process waste disposal occurs and dry filtration is necessary.
Additionally, Höcker offers each customer a maintenance and service contract after the filter system is commissioned. Currently, there are more than 1,500 maintenance and service contracts both domestically and internationally. We also offer a 24/7 emergency hotline, where customers can receive service in case of emergency, 365 days a year. All Höcker Polytechnik customers have a lifelong, free entitlement to advice on new or existing systems.
For the best possible filtration process, optimal distribution of the dust-chip air mixture in the filter as well as the best possible airflow and impact on the filter bags are required. The air and material flow pumped through the pipes into the filter expands in the raw gas area and is separated by physical gravity. Only light dusts reach the filter bag area. The air enters the filter bags from the outside and is filtered with the high-efficiency technical filter media to a residual dust content of 0.1 mg/m³/h. All filter materials and media used by Höcker Polytechnik are of tested and certified quality. The filtered air is then fed back into the air return system via fans, from where it is distributed back into the production facility.
Within this filtration process, the optimal construction of the filter housings ensures the best possible airflow to the actual bag filters. Combined with high-quality filter media and highly effective cleaning technology, the regeneration of the bag filters is achieved. The cleaning system plays a very important role in filtration technology. With the best possible cleaning even during the suction operation of the extraction system, the pressure loss of the filter is kept low, and the performance of the extraction fans remains at optimal efficiency and performance. As a result, very long standstill and operational lifetimes of the bag filters are guaranteed, often lasting many years even in multi-shift operations. The result is also low operating costs, as well as high cost and energy efficiency.
The modular, highly flexible filter system of Multistar filter systems offers a feasible solution for every customer and every space requirement. With 5-6 different material discharge types for multiflexible use, MultiStar filter systems offer individual bag filter materials adapted to the material situation as well as three different cleaning techniques such as vibration cleaning, low-pressure purge air cleaning or the jet impulse compressed air cleaning process.
All MultiStar filter systems have been pressure shock tested by independent institutes since their market launch. The filter housings are also certified according to fire resistance class EW 90, which means that, depending on the building's exterior wall construction, the systems can be installed up to 1 m from production halls. All rotary valves from Höcker Polytechnik are also tested and certified as flame-proof.
The MultiStar filter systems in longitudinal design can filter up to 500,000 m3/h. They can also be operated in positive or negative pressure mode. Negative pressure operation means that the fans are located behind the filter and suck through the filter housing. Such systems operate with fans arranged on the clean air side with the highest possible efficiency of up to 84 % depending on the system type and design. Vacuum filter systems from Höcker Polytechnik can be used up to a maximum vacuum of 5000 Pascal.
In case of higher pressure losses of the overall system, the fans are used on the raw gas side in the material and conveying flow. In this case, open transport impellers or optimised impellers with efficiencies of up to 75 % are used. The performance range of the fans is from approx. 6000 m3/h to approx. 65,000 m3/h per fan. The pressure range is covered from approx. 1500 - 7500 Pascal. If an even higher total pressure increase of the fans is required, special fans are used or support or boost fans are used. The electrical drive power of the fans in the above-mentioned range is between 5.5 and 200 kW maximum.
For the filtration of MultiStar filter systems, dry materials are necessary. The moisture content should be below 20%. For wetter materials, alternative filter media with oil- and moisture-repellent coatings are available.
The filter units of the MultiStar series can be planned very flexibly in length, width and height due to their modular design. In addition, the MultiStar series is a technically very mature filter design that has been sold worldwide for more than 15 years and well over 2,000 times. Filtration of this kind is used in a wide variety of industries. Low operating costs as well as efficient service life and durability make the MultiStar filter units particularly worthwhile. The test certificates of the units also receive the highest recognition and praise worldwide.
The heat recovery of our filter systems also offers enormous economic advantages for the operator, as heating and energy costs are considerably reduced. A MultiStar filter unit with return air system and heat recovery often pays for itself after 1.5 to 2 years.
All MultiStar filter units have been pressure surge tested by independent, leading institutes since 2005 and the rotary valves are certified flameproof.
- Pressure surge level: certified with 0.21 mbar
- Filter housing: tested and certified according to fire resistance class EW 90
- Possibility to install the filter units up to 1 m from buildings (with permission from the building authorities & depending on the nature of the building)
The MultiStar filter systems can be used in a wide range of industries where chips and dusts are produced. These include:
Wood and plastics processing
- Exhaust air filters for industry and trade
- Paper, printing and packaging industry
- Recycling industries and applications
- Metal processing
- Processing of materials containing minerals such as dry construction materials
- Production of chemical insulating materials such as polystyrene or foamed building materials
- Agriculture, grain processing
In order to minimise losses due to long pipes, it is advisable in the field of filter technology for all industries to place the MultiStar filter units as close as possible to the respective building. Furthermore, fire and explosion protection play an important role in installation planning. Thanks to the flexible modular design of the MultiStar units, we can plan and present a technical solution for any space available.
When buying a filter system, there are features and characteristics that you should pay particular attention to. In addition to a long service life and very good filter service life, these also include the following points:
- Structural conditions
- Fire and explosion protection
- Sound insulation
- Desired extraction capacity in volume flow
- Reserve capacity for later increases in machine performance
- Operating mode of the system (continuous operation without breaks or discontinuous operation with breaks for cleaning)
- Operating costs
- Energy efficiency of the extraction fans as well as the control and regulation of the systems
