The following calculation graphic can provide an initial clue for positioning your project. Your ventilation engineer can provide you with precise results based on your specific project. Appropriate documents and calculation tools are provided in certification training courses.
In principle, the following rule of thumb can be adopted:
Central positioning (location A on graph)
Controlled living room ventilation, smaller objects
A PURVECTOR is installed right after the ventilation system, central for all ventilation lines
Decentralized positioning (location B on graph)
Medium objects
Several PURVECTORS, each in front of several outlets or ventilation duct diverter installed decentrally
Arrangement in front of every single outlet
Large-scale projects
Of course, the locations can be combined. There is no overlay of PURVECTION that would resolve or limit performance. installation options
Purvectors can be easily and safely installed in any existing and new ventilation system without switching off or disrupting ventilation operations. The most effective installation option for large rooms is direct positioning in front of the ventilation outlets (position C). Flow tests have shown that correctly positioned and dimensioned swirl outlets (sources of supply) ensure the best efficiencies for general well-being and optimal purvection.
In smaller rooms, a Purvector can also be used to operate several outlets (position B). For example, the Purvector can be positioned in front of several outlets on the same channel or in front of a channel branch that serves different rooms. For smaller properties or residential buildings, the Purvector can also be positioned centrally (position A) with controlled comfort ventilation.

Purvection area of action
Purvectors can significantly and decisively improve air quality by optimising the balance of natural resources in indoor air. However, this requires that natural resources are available at all times. The physical process of purvectorization given by nature does not change the air composition in any way, as shown in the graphic below, but effectively neutralizes the pollutants, foreign odors and pathogens present in the room air.
Purvectors do not replace coarse and fine dust filters, but must be installed in addition to them.
Purvection does not replace or reduce a functioning ventilation system or periodic burst ventilation; it must be used in addition to these measures. Purvection has no influence on rising CO2 levels, due to the lack of a sufficient supply of fresh air, or due to the lack of fresh air. Even though the room air always smells relatively fresh due to the lack of fresh air supply and the continuous neutralization of foreign odors, the basic building blocks in sector A will still change unfavorably and must be corrected by appropriate measures.
Purvection does not produce any pollutants, such as ozone, nitrogen oxides or other pollutant emissions. The pollution-free Purvection is scientifically proven. Thanks to stable balance optimization in real time at all times, pollution-reducing performance is guaranteed safely and at all times.
The air we breathe consists of:
State of the art
According to the current state of technology, the majority of three systems are used to improve indoor air quality, some of which are used in addition to each other. The PURVECT AIR system does not replace existing filter technologies, but can be used in addition to them.
These are:
Air purification systems
Filter systems and UV-C lamps are integrated in a separate and closed section of the ventilation system. After flowing through the absorption of the filters, certain ventilation systems also have additional UV radiation, the air is generally well purified and flows cleanly through the air outlets into the room, where the fresh air mixes with the existing air. By means of a correspondingly high air exchange rate, the proportion of fresh air to the existing air can be increased. However, perpetrators of pollutants, pathogens or foreign odors staying in the room are not prevented from continuing to do so.
The difference to alternative systems is that Purvection neutralizes the polluters at the root, regardless of whether they produce pollutants, germs or foreign odors.
On the one hand, this reduces the risk of infection by pathogens by 5,000 times and also reduces energy costs. According to current assumptions, the lack of absences at work due to illness will also be reduced in the long term.
Ionization as an umbrella term
The ionization process does not necessarily result in a positive air-improving property, as is often suggested. Ionization simply describes a physical or chemical process.
What does ionize mean?
Ionization is any process in which one or more electrons are removed from an atom or molecule so that the atom or molecule remains as a positively charged ion (cation). The reverse process, in which an electron is captured by a positively charged atom or molecule, is known as recombination. Another form of ionization, which is particularly relevant in chemistry, is the addition of electrons to a neutral atom or molecule so that a negatively charged ion (anion) is produced. (Wikipedia excerpt from 19.10.2023)
This process takes place naturally during waterfalls, rain or thunderstorms. The cleansing and relaxing effect in the area of waterfalls has been scientifically documented. (Asthma Project Austria dated 19.2023)
Comparing air purification systems
Investigations by the Fraunhofer Institute in Stuttgart have shown that comparative measurements of different air improvement systems require the use of a very high-quality HEPA filter in order to achieve a certain degree of efficiency in the room, at the practice-oriented measurement point (see graph). HEPA filters are rarely installed in ventilation systems of normal residential and commercial buildings.
The following is a graph showing a comparable test setup and its performance at a practice-oriented measurement point directly in the room.

The vision
Neutralize pollutants, germs and foreign odors in the room air.
The mission
For years, under the leadership of Weigele Aerospace, a comprehensive team of competencies from various fields has not lost sight of the vision with much diligence, commitment and passion. Despite setbacks, it took years of development, research, tinkering and testing.
This has brought together incredible expertise in the area of “purvectorization”, which offers a new type of efficient, safe and sustainable indoor air improvement like no other system currently available on the market.
The scientific evidence
The Fraunhofer Institute in Stuttgart has scientifically proven the effectiveness of PURVECT AIR in recent years with test reports no. TR20230720, no. AN20230202, no. RS20230714, no. TR20230419, no. TR20211128 and no. TR20220901.

Measurement technology as a decisive milestone
It quickly became clear to the interdisciplinary research group that the measurement technology available on the market was unable to determine the data required for the vision. As a first development project, the right measurement technology had to be developed and provided.
A highly sensitive, mobile instrument was developed for the qualitative and quantitative classification of ions.
The underlying, novel measurement method was verified by ILM and ULM University and the underlying mathematical methods were refined.
This technology was gradually further developed by Weigele Aerospace so that these devices are easy to operate and can also be used by anyone on the go.
The Ion Counter developed by Weigele Aerospace is able to precisely measure the size, quantity, spectrum, mobility and polarity, i.e. the type of ions.

What does purvectorization mean exactly?
What does purvectorize mean exactly?
Purvectorization is a physical-technical process given by nature to improve indoor air through neutralization of pollutants, through real-time stabilized, balance-optimized purvectorization of mostly oxygen and water molecules.
The scientifically proven effectiveness of the pollutant-free neutralization of pollutants, foreign odors, germs such as fungi, bacteria and viruses in indoor air through purvectorization is reliably guaranteed at all times by consistently coordinated process technology.
Purvection takes over the natural resources present in the room air and gives them back what they have lost from the self-cleaning outdoor air on the way to the room air.
Purvection
Purvection is a physical, complex process in which the correct interplay of various elements and components uses natural resources in the room air in such a way that a purifying, neutralizing effect begins.
Only one component of Purvection is ion exchange. However, it is not completely correct and does not do justice to the process to speak of ionzation during purvection.
Ionization is the umbrella term for ion exchange (see Ionization section). With Purvection, however, this is only part of the system.
The characteristics of Purvection are:
Using AI-optimized algorithm control, two Purvec electrodes, which are precisely coordinated and designed in accordance with the requirements, deliver predefined Purvection energy in a consumption-efficient and flow-optimized airflow in such a way that the mostly important and most effective charge carriers for neutralizing the room air are purvectorized.
A third electrode ensures stable balance and optimised purvection in real time.
Drive:
Like “ionization,” “driving” is also an umbrella term as an example. It only describes the physical drive as it takes place, but still needs to be clarified in order to do justice to the corresponding technology and performance characteristics.
Purvectorization is therefore a comprehensive and complex process which only shares the umbrella concept of ionization, i.e. driving in our example.

Purvection
Various tests have shown that Purvection can only achieve its full performance when there is a uniform airflow. If the Purvection is not centered in the airflow, without turbulence, i.e. asymmetrical and in an air vortex, the effectiveness is impaired in an uncontrolled manner. In this case, the Purvector will go into fault mode and switch it off.
When the flow is uniform, the decisive correct charge carriers are purvectorized. Everything else is random and not constant and certain.
ionzation
Example of bi-polar ionization
ionzation
Our investigations have shown that when two electrodes are led into the airflow as thin, parallel rods, each with one electrode, that vortices develop around the same electrodes several times around the same one after the other, then circle around the second electrode several times again. This creates an uncontrolled vortex which, on the one hand, can cancel each other out and, on the other hand, releases ozone as a result of overload.
Only the measurable, high number of ions is not relevant for the effectiveness of indoor air improvement.
It is Purvection's balance optimization, stabilized in real time, which ensures the neutralization of pollutants in the room air.
Real time stabilization
With the third Purvector electrode and the AI-optimized Purvector control software, the parameters necessary for efficient Purvection are readjusted in real time. System fluctuations are detected and corrected.
This results in a stable balance optimization of Purvection at all times — safely, effectively and sustainably. This is done without producing emissions or pollutants such as ozone.
Balance optimization
Like a tightrope walker, the purvectorization of room air in the ventilation flow in such a way as to achieve the best possible neutralization of pollutants: safe, sustainable, efficient and maintenance-free.
