How does the filter change the operating point on my fan's performance curve?
The filter's resistance adds to the pressure the system's fan works against; the operating point on a fan's performance curve is taken from the finished filter's own data and the system's commissioning readings, and the company does not publish the pressure drop the filter adds.
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 names Eurovent Certita Certification, Certificate No. 15.06.011, which certifies a ten-pocket bag filter at ISO ePM1 70% with an A class energy rating; a rating belongs to the construction that was tested. This site publishes no fan curve, pressure-drop curve, motor load or duct data, and it does not model a particular system. NanoFlashing™ is a permanent positive polarity engineered into filter media itself. It is a physical property of the filter. The filter is passive. It draws no power, and it has no power supply, electrode, lamp or reservoir. The label for the NanoFlashing™ Air Filter states a rated airflow and a maximum face velocity, and instructs: “Do not use where this filter would restrict airflow beyond the system's specification.” It also states: “Improper installation can reduce airflow or damage the equipment.” C-POLAR markets a materials technology.
