Franz Ziel GmbH is a company based in Billerbeck, Germany and has almost 40 years of experience as a leading global provider of pharmaceutical systems and process solutions.
Ensuring aseptic conditions is our daily business. In order to live up to our guiding principle “PROTECTING LIFE WITH TECHNOLOGY“, a high degree of responsibility and know-how is required.

Based on this know-how and proven technologies, we have developed an air purifier with a special focus on flexible and mobile use in the professional sector.
Due to its multi-stage filter system, not only Covid-19 and other viruses are effectively reduced to a minimum, but the air is also cleaned of fine dust, bacteria and aerosols – for your employees and customers to breathe safely!

Air flow around the air purifier

1.500 m³/ h air volume flow (AIP 1.5T) ≙ e.g. the air requirement of approx. 50 people in the gastronomy or 75 people in the fitness area (according to DIN1946-2)


Air flow in the room

  • We have almost 4 decades of experience and know-how in the field of clean room technology for pharmaceutical applications.
  • Low background noise for concentrated work, this is achieved through the use of the most modern insulation, which is unique for air purifiers of this performance class.
  • Thermal filter decontamination can only be found on the market from very few suppliers, as it requires special know-how. However, it is crucial in order to prevent viruses from multiplying in the filter and infection of the maintenance staff when changing the filter.
  • In contrast to most air purifiers, the Air Infect Protect sucks the air evenly out of the room in a ring-shaped manner on the underside of the device and releases it again through outflow openings with adjustable air grilles on 3 sides (AIP 1.5T) or up (AIP 0.5T).
  • With a balanced ratio of flow through and exchange rate, the AIP ensures optimal flushing of the entire room.
  • A special filter seal ensures that no unfiltered, contaminated air can pass by the filter to the outside.
  • In addition to reducing disease-causing aerosol concentrations, the Air Infect Protect also removes any other suspended matter, such as pollen or fine dust from the air
  • High-quality components from German suppliers are used. (Camfil, Siemens, Ziehl-Abegg, Kalthoff)

Operation is intuitive via a modern touchpad. The device can be operated in both manual and automatic mode. In weekly operation, for example, both air cleaning and filter regeneration are fully automatic.

The reason for this is that the air purifier can only be used effectively in terms of health protection if it is handled and monitored professionally, in line with our mission statement and corporate understanding.
We do not see these prerequisites guaranteed when operated by a consumer in the private sector. We can also explain this in more detail on request. We therefore ask you, if you are interested in our product and if you are an ENTREPRENEUR, fill out the order form completely and send it to us:
