Carbon Dioxide CO₂ Filters

1. Filter Media Design by Materials

In order to filtrate Nuclear, Biological and Chemical / Gaseous contaminants, we develop, search and use various Filter Media, including:

• High Efficiency Particle Filtration

• Microbe Elimination

• Activated Carbon

• Impregnated Activated Carbon

• Other Gas Absorbents.

Particulate Phase

Nuclear and Biological contaminants are often in (fine) particulate form. Therefore Particulate Filtration is the most efficient tool in their elimination.

As the size of Airborne Bacteria and Virus can reach very small dimensions (e.g. SARS, down to 0.06 μm), we have put efforts in the ultra fine particulate filtration efficiency development. The VONE^NBC Filter Media combined with a fine particle charger, has proved to be the most efficient technology to capture these utra fine hazards in particulate form, which are, later, eliminated by UVC radiation, while trapped in the filter media.

                     Principles for Tailoring NBC Filtration Solutions:

Gas Phase

Many gases and chemical agents require a special approach in filter media design. Our two major gas filtration lines eliminate gases by adsorption (above) or by (chemical) reaction with the Filter Media.

Examples of gases not absorbed by the traditional Activated Carbon Derivatives, include Carbon Dioxide CO₂ and Carbon Monoxide CO. The filtration of CO and CO₂ requires materials producing chemical reactions with the gases, resulting in the conversion of the gas into another chemical product, and therefore, into elimination of the gas as such. We have available the Filter Media Materials and Know-How to eliminate CO and CO₂.

2. Filter Media Design by Size and Form

We design specialty filters for use in buildings, vehicles and equipment and to be used as OEM components in products of other equipment and component manufacturers. To fulfill this task, we cooperate closely with our Clients, Suppliers and Research Laboratories. 

We can design combined low-air-flow-resistance efficient filtration solutions for a wide range of particulate, microbial, nuclear and gaseous contaminants.

We also offer tailored high efficiency low-flow-resistance Filter Bags in different shapes, for large scale, Client-Specific Particulate filtration needs in Specific Sizes and Forms as well as

Tailored CO₂ Filter Cartridges for large scale Client-Specific Carbon Dioxide filtration needs.
