Hayflow

Summary

Product identification

The HAYFLOW™ is a patent-pending filter element designed to combine the benefits of both bag and cartridge filters. It offers outstanding filtration performance with an enlarged surface area and improved dirt-holding capabilities.

Mechanical / hydraulic

• Design: Two concentric cylinders of high-quality, extended-life filter media, formed with unique welding technology to create a no by-pass seam.
• Sealing: Fitted with Eaton’s patented SENTINEL® sealing ring to ensure a positive seal and prevent bypass.
• Flow Path: Process fluid enters the inside of the element, passes through it, and exits through the vessel outlet. Filtered-out material remains inside the HAYFLOW element.
• Dimensions:
  • Filter Element: Ø 180 mm x 700 mm (for 'L' size)
• Compatibility: The cylinder diameter matches a standard filter bag, allowing for easy retrofitting into existing systems. Existing bag filter vessels require only a new HAYFLOW restrainer basket.
• Residual Liquid: Retains only 25% of the residual liquid volume of a similarly sized filter bag.
• Weight: When full, the element weighs up to 75% less than a filter bag. A full bag can weigh up to 15 kg.
• Construction: Rugged cylindrical construction provides strength over a full range of operating differential pressure. All-welded seams.
• Surface Area: Up to 65% greater than a similar size filter bag.
• Vessel Size Reduction: New bag filtration systems can be designed with filter vessels up to 50% smaller due to high flow rates.

Operating limits

• Materials of Construction:
  • Standard Elements: Polypropylene and polyester construction.
  • Filter Media: High-quality, extended-life DURAGAF™ needlefelt media with fine fibers and higher pore volumes. Melt-blown polypropylene media available for high micron retention and selective absorption. Any weldable filtration media can be used, including multilayered construction.
  • Sealing Rings: Polypropylene or polyester SENTINEL® sealing rings.
• Temperature: Designed to perform over a wide range of temperatures.
• Micron Rating: Available with high micron retention ratings. See the official PDF for exact tabulated values.

Features & Benefits

• Outstanding filtration performance.
• Longer filter element life and less frequent changing (up to 5 times greater life than filter bags).
• Reduced running costs.
• Higher flow rates possible.
• Reduced filter vessel size for new installations.
• No by-pass, thanks to 100% welded construction and SENTINEL® sealing ring.
• Up to 35 times more effective than standard filter cartridges.
• Low pressure differential results in less energy consumption.
• Easier maintenance: filtered material stays inside, lower residual liquid volume, and lighter weight when changing.
• Easy extraction of the element using handles on the SENTINEL ring and center sleeve.
• Quick and easy installation as the element is smooth and fits the basket walls without crimps or pleats.
• Easy retrofitting into existing filter vessels (with appropriate restrainer basket).
