Selecting a Pressure or Vacuum Convey System?
First ask yourself these two questions.
1. Where is the product now and where do you want it conveyed?
2. How many product pick-up points and how many destinations?
A system with a single pick-up point to multiple destinations is generally discussed as a pressure system first to use one air source and divert to multiple locations. An example of this type of system would be a company that has a bulk ingredient in a silo. The bulk material will then be conveyed to multiple destinations in the plant for different products (such as flour as a base for many baking products).
A system with multiple pick-up points conveying to a single destination is generally discussed as a vacuum system first. This way, only a single vacuum source is needed to convey products from many destinations. An example of this type of system would be a minor ingredient system for a batch process. Each ingredient can be metered into the convey line one at a time and vacuumed to a scale hopper and be ready to discharge.
A system that only has a single pick-up and a single destination can be conveyed with either vacuum or pressure. With all factors being equal, a pressure system will be more cost effective in the long run due to power consumption (blower horsepower).
