Maintaining a specified level of fluid cleanliness is critical to the operation and reliability of aerospace fluid systems and equipment. Ultipleat filter elements feature a laid-over pleat geometry which offers improved performance and a reduction in filtration costs.
The pleats of Ultipleat filter elements are designed to support each other along the entire length of the pleat. The total flow resistance is similar, regardless of where along the pleat the flow passes through the medium. This creates a uniform flow velocity through the filter element and, therefore, uniform build-up of dirt within the filtration medium. The result is greater dirt-holding capacity and longer filter element service life.
Features
- Laid over pleat geometry; significantly increased area and uniform flow distribution (compared to traditional fan pleat)
- High-strength construction
- Size reduction (optional)
Benefits
- Extended filter element service life (same space envelope) or
- Smaller space envelope and reduced weight
- Consistent performance throughout filter element service life
- Reduced filter element and assembly weight with similar service life and efficiency

Longer Service Life or Finer Filtration...Your Choice
The increased filtration area due to the laid-over pleat construction combined with the uniform flow distribution leads to a significant improvement in filter element service life when compared to a fan pleat construction in the same space envelope. Alternatively, customers can choose to have a finer filter and still obtain the same filter element service life as a fan-pleat design in the same space envelope.Service Life of Fan-Pleat vs. Ultipleat Filter Elements
