HEPA filters are resistant to airflow, requiring a static pressure fan.
“Concentrated Compression Blade (CCB) for high-static pressure of demanding applications such as radiators, the CCB is engineered to focus the inner weaker circle of air outwards, allowing the outer section to pressurize and compress the air.”
“Tuned for high pressure air delivery directly to components.”
“The PH-F120MP, a high static pressure fan, can have the ability to overcome the airflow restriction caused by high fin density.”
“This 12 volt DC fan gives you extremely high airflow of 185.87 CFM and extremely high pressure of 12.15 mmH2O at a maximum speed of 4200 RPM and 58.7 dBA of the noise level.”
