Powder Systems

Mediprint's Powder system consists of various interlocking components.

Powder systems by Mediprint

Powder systems & powder extraction systems

Our powder extraction system prevents contamination of your printed sheets, reduces soiling and wear and tear of the printing machine, and reduces the fine dust pollution in the printing enviroment. An extraction system is indispensable, because with every sheet that is printed there is also some excess powder in the machine. This is extracted by the suction system precisely and efficiently. We offer you the best conditions for an optimal print result for further processing under the highest hygiene standard.

With Mediprint’s Modular Powder & Extraction System (MP&ES), the powder is applied very precisely, with our specially developed modular system concept in order to reduce powder turbulence to a minimum at high printing speeds during the dusting process.

On the one hand, we use our AST, which is manufactured according to your wishes, as a powdering system. The powdering step then takes place within the encapsulated spray chamber and is finally picked up and processed again by our filtered suction system.

The Mediprint suction system reliably loosens powder residues that would otherwise stick to the machine and cleanly removes the loosened dirt without impairing sheet travel. As a result, the printed sheets are kept free of falling clumps and the cleaning cycles as well as the durability of the machine are optimized.

The Mediprint powder system, which is individually tailored to your machine format, ensures precise and economical powder dosing, even with high powder quantities, with minimal machine stress and maximum suction power.

Powder Spraying System

Stationary powder spraying system for application of dry, flow able powder on web, consisting of

  • Two parallel working powder dosing units
  • Standard dosing units: D25/t0.5
  • Total output min/max.: 60-3.800gr/h
    (reference powder KSL S5/20 starch – grain size 20μm)
  • Two nozzle distributors (with 8 outlets, altogether 16, can be modified)
  • Spray bar 1.600mm with 48 Micro Jet single nozzles
  • Two low maintenance Rotary Multi-Vane Compressor 40m³/h each
  • Powder container with stirring device for up to 20-liter volume

The system will be supplied in a compact cabinet. An automatic adaption of powder quantity to the respective speed of web is integrated. Control via speed signal (0-12V) to be provided by customer. Monitoring of powder quantity by two capacitive sensors and monitoring of air pressure via pressure sensors fixed at the injector. This system enables application of pourable powder with medium-sized particles of 20-30μm.

Security information

Many types of dust are flammable and can, in conjunction with an ignition source, lead to filter fires and dust explosions in individual cases. Therefore, the operator of an extraction system has to take appropriate steps to avoid these specific dangers and especially has to ensure that during operation of the extraction system no ignition sources will be sucked. Additionally, he must meet the ATEX-directives.

System is delivered in a compact metal casing. The regulation occurs by the internal control box. Automatic adaption of powder quantity to the respective speed of web is integrated. Control via speed signal (0-12V) to be provided by customer. Monitoring of min. powder quantity by light barrier sensors and monitoring of air pressure via pressure sensors fixed at the injector. This system enables application of pourable powder with medium-sized particles of 20-30μm.

1 x ESC – spray chamber

Spray chamber with preparation for both sides connection to extraction system,

  • to avoid powder contamination of the environment
  • Exhausting including pyramid shape cartridge extraction device
  • Inspection opening upside for easy cleaning and film feeding
  • Pneumatic vibration cleaning system for permanent prevention of powder accumulation (Compressed air supply 4-6 bar provided by customer)
  • lonisation unit to prepare the film in front and after the spray chamber
    (consisting of high voltage power pack and ionisation bars El-RN)
  • System operation via powder system AST
  • Infeed size for max. web width 1.800 mm
Powder Extraction system

Stationary extraction system for dry dust and powders up to grain size 25mm. Innovative, two-parts housing structure of sandwich panel. For a compact and solid design and low sound level. Appropriated for dry, burnable powders.

Unit design

Filter unit:

  • Housing structure of sandwich panel with conductive internal coating
  • Inlet air entry with inspection opening
  • Integrated impact separator, coarser particles will be pre-separated for
    low dust concentration and long service life of the cartridges
  • Long life filter cartridges (oil and waterless compressed air supply with 4-6 bar required)
  • Mobile dust collection drawer with a volume of 150, two integrated, closable cartons, for dust-free discharge of the filtered material
Control unit
  • Integrated fully automatic control unit with on-/off switch, motor protection,
    warning signal for false direction of rotation and filter change
  • Filter cleaning unit with differential pressure monitoring
Technical data
    • Max. airflow: 2,900 m3/h
    • Max. negative pressure: 3,400 Pa
    • Motor: 3 kW, 400 V, 50 Hz
    • Intake diameter: Ø 200 mm
    • Compressed air adapter: 3/4″ (extern required compressed air 4-6 bar)
    • Air consumption: 19 I per impuls at 4 bar preassure
Custom builds and modifications

Mediprint Apparatebau GmbH is very proud of his history of highly modified and specifically fitted solutions for our customers. We find the best solutions for your specific needs, without unneeded additions driving prices.

Unique selling points

In addition to numerous product-specific unique selling points, Mediprint relies on the following features for all of its products:

Robust high-performance nozzles

Our tried and tested spray heads, designed for continuous operation, are ideally matched to our built-in tube technology and thus ensure a perfect powder result in continuous operation

Tube technology

Our tube technology with self-developed air-blow process enables you to dust evenly and economically, economically and at the same time with perfect results

Customized installations

We take the time to find the perfect solution for your problem and requirements, regardless of whether it is a more cost-effective retrofit or complex special requirements, we are extremely flexible when it comes to your machines and production and have the necessary know-how


Mediprint Powdersystem can distinguish between different input signals and therefore differentiate between use cases


The menu offers 3 different languages (ENG, FRA, GER) and can be extended by further languages if required

Aluminum housing

Mediprint deliberately uses aluminum enclosures to weather the heat and dust in packaging and printing machines

The services we provide for you!


Mediprint offers selected customers a subscription service on its own products at special conditions. This allows customers to automate the process free of charge and save additional money.


Especially for customers whose workload and machine park size fluctuate, we offer individual leasing contracts for our tape inserters in order to streamline their cost structure and at the same time to increase flexibility.


Since most of our products are manufactured in batch sizes <25, individualisation in production can be realised at relatively low cost.
