How can NanoFlashing serve data centres and cleanrooms?

Could the filter introduce particles that matter to a semiconductor cleanroom?

A cleanroom requirement is matched against a named test or found not to be covered by one.

The company publishes no cleanroom classification, no shedding measurement and no packaging cleanliness class. The label instructs: “Store flat or on edge in the original packaging, indoors and dry, away from direct sunlight and moisture. Do not stack loads on the media.” A request for a measurement it has not published goes to [email protected], listed on the Contact page.

Is outgassing characterised for use near sensitive optical equipment?

The filter is passive. It draws no power, and it has no power supply, electrode, lamp or reservoir. The polarity is a positive electric charge at rest. C-POLAR publishes no outgassing measurement for the material. A requirement of that kind is matched against a named test or found not to be covered by one, and a question about a named material and a named use can be sent to [email protected].

Would the material affect an electrostatic-discharge control programme?

The filter has no electrical connection, and its charge is a property at rest.

The filter is passive. It draws no power, and it has no power supply, electrode, lamp or reservoir. The polarity is a positive electric charge at rest. It is measured as surface charge density, in nanocoulombs per square centimetre.

C-POLAR publishes no assessment of a static-control programme and none of a high-voltage installation. An assessment of that kind is made by the facility that runs the equipment, for the equipment it runs.

Can a filter retrofit change a data centre's hot-aisle and cold-aisle balance?

The label instructs: “Do not use where this filter would restrict airflow beyond the system's specification.” What that means for the balance between hot and cold aisles is decided by the design of that system.

The Validation page names Eurovent Certita Certification, Certificate No. 15.06.011, an ISO 16890 ePM1 certification with an A class energy rating. The one building energy measurement the company publishes is at a financial landmark in London over six months from March 2024 to September 2024, measured before and after the air handling unit filters were changed to NanoFlashing™. The Validation page reports: “Particulates down 92.1%, bioaerosols down 94.2%, energy down 18%.” The label also states: “Improper installation can reduce airflow or damage the equipment.” The label states: “Results in a building depend on the system, the airflow, and how well the filter fits its track.” The filter is specified by nominal size, rated airflow and maximum face velocity.

Can it be integrated into a fan-filter unit without invalidating its tested configuration?

Building the media into a fan-filter unit is the work of the partner that makes that unit, and that partner's own testing decides what the unit can be said to do.

The Terms of Use state: “A prospective partner or manufacturer must perform its own testing, validation, compatibility work, safety review, risk review, and quality controls for its proposed product and use.” The Terms of Use state: “A reported result describes only what the identified test found.” They also state: “Each reported result belongs to the C-POLAR material, component, or prototype that was tested. The maker of a finished product confirms the performance of that product, because construction, processing, storage, wear, cleaning, other components, and actual use are part of it.”

Every commercial NanoFlashing™ product is made by a manufacturing partner, in their facility, in their format. Development runs configuration by configuration, and each partner controls what is said about the work.

The company publishes no measurement of what a filter picks up before a system is started. The polarity is a positive electric charge at rest. It is measured as surface charge density, in nanocoulombs per square centimetre. NanoFlashing™ attracts negatively charged particles through electrostatic attraction.
