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

The company publishes no cleanroom classification, no shedding measurement and no packaging cleanliness class.

A requirement of that kind is matched against a named test or found not to be covered by one. 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.”

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.

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

It can: the filter's resistance adds to the pressure the system's fan works against, and the label directs that it is not used where it 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.

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: “A test of C-POLAR material, a component, or a prototype does not establish the performance of a finished product that incorporates it. Construction, processing, storage, wear, cleaning, other components, and actual use may change the result.”

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 charge is present whether or not air is moving, and 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. The filter captures airborne particles mechanically and by electrostatic attraction.

The label directs that the filter is stored flat or on edge in the original packaging, indoors and dry, and that a filter whose media is torn, crushed, wet or visibly damaged is not installed.
