The Electric Pump is the most common type due to its widespread use across different industries such as Medical, HVAC, Food Processing and Bulb Manufacturing. These pumps are best used when a high vacuum flow rate is desired (2-10 CFM) with a trade-off of a lower vac level (8-16″ Hg) – often times the maximum vac level isn’t even listed in the product specs.

Bottom Line – Fluids and particles are enemies of these types and perform best when evacuating dry gasses.
