Sustainable air purifiers - Clean air

ARPACK’s photocatalytic air purification and decontamination system offers the most advanced and effective method for purifying air in applications such as: 

The special photocatalytic purification and decontamination process enables cost-efficient, sustainable and highly effective air purification for private and commercial use. 

AIR PURIFICATION USING TITANIUM OXIDE AND PHOTOCATALYSIS

The chemistry behind Arpack’s success

AIR PURIFICATION USING TITANIUM OXIDE AND PHOTOCATALYSIS

Titanium oxide (TiO2) is a semiconductor. In such compounds, the electrons can be in two states: free and bound. Normally the electron is bound, i.e. it is connected to the ions of the substance’s crystal lattice, forming a strong chemical bond.

It is necessary to expend more than 3.2 electron volts (eV) of energy to “knock” the electron out of the lattice (for comparison: The kinetic energy of a flying mosquito is about one trillion eV).

This is the amount of energy carried by a quantum of light with a wavelength of less than 390 nm. The light quantum “pushes” an electron out of the lattice and forms an electronic gap or simply “the hole”. The electron and the hole move actively within the TiO2 particles. As a result of the movement, they either recombine (meet, “marry” and return in a bound state) or break free at the surface and are immediately captured by it.

Both the hole and the electron are incredibly reactive. The whole surface being a catalyst creates a strong oxidation field. Oxygen coming into contact with the catalytic surface and gaining a free electron results in an oxidative radical O- that can destroy (oxidise) any organic compound.

The hole in turn reacts with the first organic compound encountered on the surface. The hole pulls an electron out of the compound structure and thus its electron is missing, causing the compound to dissolve into water and carbon dioxide.

Each time an electron/hole pair perform chemical reduction and oxidation, the hole rises to the catalyst’s surface like bubbles in a champagne glass, releasing a new pair. The oxidation process continues as long as light falls on the catalyst. 

The photocatalytic filter mineralises organic molecular impurities, mainly to carbon oxide, oxygen and water.

The best performance

ARPACK air purification units

with innovative technology from space travel

Our ARPACK AirClean technology enables effective reduction of microbiological air pollution without the disadvantages of traditional technologies associated with the release of ozone, the use of harsh UV-С radiation and expensive replaceable HEPA filters.

Our air purifiers do not contain mercury vapour, do not collect organic air pollutants (including all types of microflora) and do not require replacement of main operating components for continuous operation of up to seven years.

Schematic structure of

ARPACK air purifiers

The air flows by means of a fan (1) first through the dust filter (2) and then through the porous wall of the photocatalytic glass element (3). Volatile organic compounds, bacteria and viruses in the air are absorbed by the photocatalytic filter and mineralised into carbon dioxide and water vapour under the influence of an LED UV-A light source (4).

Confirmed
effectiveness

Our air purification devices have been tested and their effect confirmed by renowned institutes and laboratories.

The main types of volatile organic compounds that are removed by our units include:

Opinions of happy ARPACK AirClean owners.

Uwe H. | Use case:: AC20

"My wife suffers from allergies and is the biggest critic of new appliances, but since we got the AC 20 she doesn't want to give it back."

Beate P. | Use case:: AC200

"The air purifier seems to be doing its job very well, we’ve had fewer sick children despite the pandemic and the children like the animal motif." – Beate, Fourth Grade Teacher

Tilo M. | Use case:: AC50

"We use the AC 50 with the fan in our living room by the fireplace. The whole family are big fans of our new air purifier."
