In laboratories, air quality is an important factor in assuring production and research quality. Airborne contamination can, at worst, lead to product recalls, expensive investigations and cleaning procedures, not to mention a weakened image and credibility. Reliability and repeatability of research results and protecting the staff from particles in the air are also a concern.
In laboratories, our strength is removing nanosized particles from the air. Genano Technology has been tested down to three nanometers particle size and it is capable of removing both organic and inert matter. Additionally, all living contamination is eliminated as part of the air purification process. Read more about our research results
Technically, a cleanroom is an environment with a low and controlled level of environmental contaminants such as dust, airborne microbes, fine particles, and chemicals. The international ISO 14644 standard establishes classes of air cleanliness for airborne particulate levels in cleanrooms and associated cleanroom areas, (clean zones).
The cleanroom ISO classes are defined according to particle count per cubic meter (depending on particle size) at certain conditions. To verify compliance with ISO class a discrete-particle-counting instrument is used to determine the concentration of airborne particles, equal to and greater than the specified sizes, at designated sampling locations.
In addition to particle count, other important factors in cleanroom design are the rate of air volume change per hour (ACH) and pressure difference between the clean room and outside environment. In some circumstances, relevant regulatory agencies may impose supplementary policies or restrictions. In such situations, appropriate adaptations to the standard testing procedures might be required. Organization-specific Good Manufacturing Practice (GMP) guidelines must also be considered.
The ISO 14644 standard addresses particles within the size range of 0,1- 5 um, while a new standard for monitoring of air purity by concentration of airborne nanoscale particles (pka ultrafine particles) is currently under development (ISO/DIS 14644-12).
HEPA filters commonly utilized to filter supply air flow in a cleanroom can only collect particles of 0.3 microns and bigger in diameter, which renders need for additional air decontamination technologies such as additional air purifier units in the room. Also, while most sub-micron and macro particles in cleanrooms can be related to human activity, nanoparticles are generated by electrostatic discharge, chemical reactions such as oxidation, and gas phase nucleation. Therefore majority of the nanoparticles in cleanrooms are process-related and cannot be effectively removed by ceiling-mounted pre-filtering HEPA systems.
Genano air purifiers are designed to protect your products, research and staff from airborne contamination. With Genano, you can build new laboratory cleanrooms rapidly and cost-efficiently; raise the air quality of an existing cleanroom; and protect your staff.
With Genano laboratory air purifiers, ISO class 6-7 cleanrooms can be reached cost-efficiently and rapidly. Genano air purification technology has been tested according to the ISO 14644 Standard. The solution can be designed to fit any room-spesific needs for ACH, pressurization or other details. Genano air purifiers also work as additional purification system in existing cleanrooms and clean zones, where nanoscale decontamination is needed.
Building cleanrooms with Genano is highly cost-efficient and fast compared to traditional HEPA systems. Only minor piping work is needed to connect the Genano air purifier to central ventilation. All of the supply air enters the room through the unit, while air flow is controlled to create positive pressure difference to outside environment. A second unit is utilized to constantly circulate and purify the air from any process and human-related contaminants.
In addition, Genano air purifiers are equipped with high-surface-area active carbon collectors that remove gaseous substances.
“Since using Genano air purifiers we have had a marked increase in our success rates in terms of first time pregnancy results and less miscarriages”, summarises Dr.
The air brought to the laboratories is decontaminated by a Genano air purifier before entering the room. In addition, stand-alone Genano units are
used to circulate and purify the air in critical spaces. “Genano system is a perfect solution for our needs”, summarizes Mr. Tenkanen.
