In a particularly preferred embodiment, the air-nuclide reduction device according to the invention preferably has a radial housing, depending on the size of the device, any number of glass probes, preferably arranged radially, preferably from 1 to 30 probes, preferably 4 to 15 probes may be present to an electrical To form field for the production of oxidizing gas. Laterally, the oxygen is supplied, preferably by means of a fan or ventilator, preferably from the ambient air to be routed past the probes and then carried out with oxidizing gas, such as ozone on the lower side of the air-depletion device, preferably one Fan or fan. The probes can be used in the

If the probes are arranged in the form of a probe package, 2 to 8 probes can be arranged vertically next to one another or horizontally one above the other, wherein a plurality of such probe packs can be arranged inside the housing of the air germ reduction device. The oxidizing gas produced in the air-nuclide reducing device of the present invention, which is mainly ozone, is generated in an amount such that an ozone concentration of preferably at least 180 μg / m ³ , preferably 300 ppm to 1000 ppm, is present at every angle of the room.

The device by means of which an electric or electromagnetic field is provided for the formation of oxidizing gas can be any which oxidizing gas is provided, it is preferred in the device, via which an electromagnetic or electric field is provided for the formation of oxidizing gas, by at least one probe, preferably by up to 4 probes, more preferably by up to 10 probes but it can also be up to 20 or more probes, depending on which effect is to be achieved.

These probes which are used are preferably each a hollow glass probe filled with an electrically conductive gas, preferably filled with at least one noble gas. In a preferred embodiment, the probe consists of a cavity of glass. The glass probe has a glass end at one end and at its other end, protrudes a metal piece, which may be connected to an energy supplying device, such as a piece of metal wire in the probe, with which it is connected to a device that the provides necessary energy, preferably the glass probe is connected via a positive clamping connection, preferably a metal closure. The glass probe is preferably with at least one electrically conductive gas, preferably at least one noble gas or noble gas mixture, at a reduced pressure of preferably 0.1 to 1000 mbar, preferably 0.1 to 500 mbar, particularly preferably 0.1 to 10 mbar, very particularly preferred 2 mbar to 5 mbar filled. Preferred noble gases are any desired mixtures of noble gases or preferably of argon and neon, which may additionally contain one or more other noble gases, mixtures containing more neon than argon being preferred, preferably 0% by volume of argon to 100% by volume .% Neon, preferably 10 vol.% Argon to 90 vol.% Neon, more preferably 30 vol.% Argon to 70 vol.% Neon, most preferably a mixture of 30 vol.% Argon and 70 vol.% Neon. In a preferred embodiment, the probe has a grounding device connected to ground. This current-carrying device is preferably a wire Metal passed from the glass end of the probe along it to the earth. Preferably, the wire is guided outside or inside the probe along to the ground. If the wire is passed inside the probe, the probe must be double-walled, with the wire in the outer probe cover preferably in contact with oxygen.

The Luftkeimverminderungsvorrichtung invention generates the oxidizing gas directly to a glass probe, preferably from the surrounding atmospheric oxygen or pure oxygen, by the principle of silent electric gas discharge an electric field between at least two poles, here the one probe and there the other probe or a Metal piece in the case in which only one probe is present, which are separated by an insulator, namely air. From a limiting field strength, electrons are generated in the electric field due to continuous discharging, which cleaves the oxygen contained in the ambient air into radicals, such as highly reactive substances (oxygen in the statu nascendi), such as atomic oxygen, which is mainly formed.

Hydroxyl ions, ozone, and others formed. After the application of an alternating voltage of up to 35,000 Hz, a discharge process is created between the electrodes of the glass probes and, linked to this, an electric field with a high electron density. The radicals are formed by molecules of the air are hit by electrons and thereby reach a higher energy level. The atomic oxygen, which is highly reactive, reacts with the germs in the air and on objects, thereby producing ozone. It is surprising that especially in the range of the current intensity and the frequency according to the invention, a great deal of atomic oxygen is produced. The atomic oxygen is formed both before the formation of ozone and during the decomposition of the ozone. The ozone formed in the air-nuclide reducing device according to the invention decays, as far as it comes in contact with moldings, in particular in the aqueous medium within about 10 minutes to half the value of its original concentration. With the Luftkeimverminderungsvorrichtung invention can under Laboratory conditions 1 to about 300,000 ppm of ozone (this is measurable) are generated, which can be deduced indirectly on the concentration of atomic oxygen, because if this is not consumed, also slightly reacts to ozone.
