Compressed Air Requirements

All HafcoVac industrial air-powered vacuums operate using compressed air. The air supply requirement is determined by your application and the availability of your air supply.  The power and performance of the HafcoVac venturi is determined by the amount of air consumed. Increased CFM results in being higher performing units.

There are many factors that will help you determine if your compressor is adequate. Horsepower, tank size, plumbing and current utilization all play a role. Your compressor must be able to deliver a minimum of 60 or 100 CFM @ 90 PSI, depending on which HafcoVac model you choose. A general rule of thumb is that most compressors are capable of delivering 4 CFM at 90PSI for every horsepower they are rated. For example, a 5 HP compressor typically will deliver 5HP x 4 CFM/HP = 20 CFM. HafcoVac recommends the following minimum compressor size to power our vacuums:

Vacuum Heads

HafcoVac Minimum Compressor Size

18 CFM Models

5 HP Minimum

48 CFM Models

10 HP Minimum

85 CFM Models

20 HP Minimum

185 CFM – Dual Venturi Models

40 HP Minimum

While HafcoVac vacuums will operate when air supply doesn’t meet specifications, please be aware that performance will be greatly reduced. If you are unsure if your facility’s air supply is capable of delivering the minimum requirements, choose the next size down. A 60 CFM pneumatic vac properly supplied will outperform a larger undersupplied model.
