No fuel or electricity required: This is a huge plus and it saves a lot of time and money. Vacuum ejectors do not need any electricity or fuel to run. All they need is the motive gas (compressed air in most cases) to work. This makes these vacuum generators even more affordable and saves a lot of bucks in the long run
Quick replacement: Since there aren’t any moving parts and vacuum ejectors don’t have a long installation process, replacement of these type of vacuum pumps is a really quick process.
So, despite their small size and simple design, vacuum ejectors provide a very affordable and efficient way of vacuum generation for various systems. Not only do these save you a lot of money they also save a lot of effort as well.
