The newly re-designed MultiStar Filter System is innovation at its finest. The second generation filter system, like Hocker Polytechnik, is Always One Idea Ahead.
Industrial dust collectors from Höcker Polytechnik
MultiStar filter systems at a glance
What the dust collectors from Höcker Polytechnik can do
The purpose of a dust collecting system is the dust extraction, to clean a certain amount of air from production processes of processing machines with a dust/air mixture to such an extent that specified limit values for dust and pollutants are reliably adhered to. The filtered air from the industrial dust separators can usually be returned to the production rooms as clean, warm return air. A number of aspects must be taken into account here, such as the composition of the dust/air mixture, the particle sizes, the filter medium and the operating mode of the systems.
Applicable in both industry and trade, the dust collecting systems are suitable for sectors such as: Woodworking and processing, plastics processing, paper, printing and packaging industry, wood industry, furniture industry as well as everywhere where process waste disposal takes place and dry filtration and dust extraction is necessary.
Hoecker also offers each customer a maintenance and service contract after commissioning of the industrial dust collecting system. In the meantime, we have more than 1500 maintenance and service contracts at home and abroad. In addition, we offer a 24/7 emergency service hotline where customers can receive emergency service 365 days a year. All Höcker Polytechnik customers have a lifelong, free-of-charge entitlement to advice on new or existing systems.

Productivity increases through air filtration - filter systems from Höcker Polytechnik
Production machines, regardless of the industry, generate chips and dusts through the machining of material. Here is an efficient dust extraction by a dust separator obligatory to ensure high quality production processes. Due to the outstanding filtration results of usually 0.1 mg/m3/h combined with fresh air admixture or heating, the operators of our dust collecting systems save heating costs and there is a pleasant room and working climate.
Industrial dust collectors from Höcker Polytechnik work for you in the process waste disposal of production processes. We keep your production processes clean so that limit values for maximum dust concentrations at the workplace are observed.
For this purpose, the processing machines are connected to the dust extraction systems through precisely dimensioned pipelines and extracted with the necessary energy and speed. The extraction fans generate a precisely calculated negative pressure beforehand. In this way, the dust deputy extracts the production machines properly and keeps them free of dust and chips.
Efficient operation of the dust collecting systems is important to us and to you. We can meet this standard through the optimal design of the filter systems with regard to blowing-in, pre-separation, cleaning and filter media. This keeps the electrical energy costs and the operating costs of the dust deputy very low.
The modular, highly flexible module filter system of the Multistar filter systems offers a feasible solution for every customer and every available space. With 5-6 different material discharge types, the MultiStar filter systems can be used multiflexibly and offer individual bag filter materials adapted to the material situation as well as three different cleaning techniques such as vibration cleaning, low-pressure rinsing air cleaning or the Jet Impulse compressed air cleaning process.
All MultiStar filter systems have been pressure shock tested by neutral institutes since their market launch. The filter housings are also certified according to fire resistance class EW 90, which means that the systems may be built up to 1 m from production halls, depending on the external wall construction of the building. All rotary valves from Höcker Polytechnik are also flame penetration tested and certified.

All rotary valves from Höcker Polytechnik are also flame penetration tested and certified.
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.
Dry materials are required for the filtration of the MultiStar filter units. The moisture content should be below 20 %. For more humid materials, filter material with a corresponding oil- and moisture-repellent coating is available as an alternative.
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 airlocks 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
