Automatic Screen Filters vs Hydrocyclones

Automatic screen filters and hydrocyclones are both used to protect water systems from solids, but they work differently. Hydrocyclones separate heavier particles using centrifugal force, while screen filters physically capture particles larger than the screen openings.

Main Differences

• Hydrocyclones are best for heavier particles like sand
• Screen filters capture particles based on size
• Hydrocyclones do not provide a defined micron cutoff
• Screen filters are better for mixed debris and equipment protection

In some systems, hydrocyclones and screen filters are used together. A hydrocyclone may remove heavy sand first, while a screen filter removes remaining suspended debris before it reaches downstream equipment.
