I hope this message finds you well. I'm currently working on an air filtration project where I'm utilizing a specific pump model. The system is designed to filter air through an area of 78.5mm², but I've noticed that I'm only getting around 0.5CFM with my current setup while trying to push air through a filter with a 4um pore size. I'm looking to improve the airflow significantly and would like to know if you have any stronger pump options available that could help me achieve a flow rate of 3.5CFM under these conditions. Your expertise and recommendations would be greatly appreciated as I aim to enhance the efficiency of my system. Thank you for your assistance!
