How does dirt and particles affect a vacuum cups system?

Electric vacuum generators: The suction of particles through the suction cups can cause irreversible failure of vacuum pumps or turbines.

Traditional pneumatic vacuum generators: The internal orifices of the generator are very small and quickly become saturated when dust or particles are sucked in. The generator stops suctioning. In some cases, they include internal membranes that do not close properly when dirty.

Common solutions:

• Suction cup filters (mesh type or filtering grids) – Limit the air flow rate. In very dirty environments, they quickly become saturated, because the effective surface area is very small. Depending on their micronage, they may allow finer particles to pass through and may not be effective.
• Inline vacuum filters – Good solution in many cases (if properly sized), but require periodic inspection and maintenance.

Suggested solution:  Special pneumatic vacuum generators (ejectors) for applications with particle presence.

• No suction filter is needed. Internal construction allows passage of aspirated particles, that can be driven by exhaust.
• The removable lid allows easy cleaning.
• Models with a counter-blow tank discharge a powerful stream of cleaning air in each cycle.
• They do not clog or break down when suctioning dirt, dust or particles.
• The suction cups of the system do not need individual filters, allowing the total flow of the suctioned flow to pass through.
