CV-15HS Vacuum Generator Pneumatic Exhaust Air Ejector Vacuum Ejector Air Fitting Vacuum Suction Cup with

Es un producto muy bueno

Why did you pick this product vs others?:Good value. Unit worked well in producing the required vacuum over a range of input compressed air pressures. However, no specifications were supplied with the unit or are available on the vendors page on Amazon (vacuum volumetric flowrate vs. desired vacuum pressure). I had to run a series of bench engineering tests to develop the necessary information on the unit. I deducted 1 star because of lack of specifications/engineering information.

you will need some additional parts to set up. at the time of writing (2025) pressure valves were available on amazon for $15 USD (optional) the rest can be purchased from Harbor freight for under $10 USD. so 25-40 USD for the whole set up.

There is a fine point of flow rate/pressure where too much can reduce resulting vacuum, but it's impressive all the way through it's ability.

I have several of these vacuum generators, and most of them will pull 26.5inhg. I had 1 that only pulled 24inhg. These work just as good as Airtech, but a fraction of the cost.

Used to clean out engine cylinders - ran up to 150psi
