I'm looking for a highly effective air pump suitable for my air bearing turntable project. The pump needs to provide an airflow of around 7L/min with a consistent air pressure of 0.5 bar. It's crucial that the airflow remains smooth and uninterrupted, as this will directly impact the performance of my project. Additionally, noise levels need to be minimal, so a design that prioritizes low noise and vibration is essential. I also require very low pulsation to ensure the integrity of the turntable's operation. If you have any suitable options that meet these parameters, please let me know your recommendations and specifications. Thank you!
