DC3.7V mini air pump for adult products  

How strong a mini vacuum pump do I need? Determining the required dc electric vacuum pump strength depends primarily on your specific application and job requirements. Here are some key factors in determining the strength of your vacuum pump required: Vacuum requirements: Identify the vacuum level required for your process or experiment. For example, some applications may require very high vacuum levels (e.g., electron microscopy, semiconductor manufacturing, etc.), while other applications may only require lower vacuum levels (e.g., food packaging, medical suction equipment, etc.). Flow Needs: Determine the pumping rate or flow rate you require. This depends on the size of the container being pumped, the amount of gas that needs to be exhausted, and the required exhaust velocity. Gas composition: Consider the gas composition in the container being pumped. Different gases may require different types of vacuum pumps, for example, applications containing corrosive gases or vapors may req…
