Hollingsworth & Vose is a worldwide leader in filtration solutions. We have the broadest range of wetlaid and drylaid process technology platforms for filtration applications. One of our core capabilities is developing and producing multi-layer composite filter media. The construction of the composite is dependent on the application and exact requirements.
What Is Composite Filter Media?
Composite filter media contains two or more layers of filtration materials that are combined and bonded together to create a filter media with enhanced functionality designed for a specific industry application.
Many different filtration materials and combinations of substrates can be used to create composites, with each layer providing different filtration properties and physical characteristics. H&V composites can be designed to meet a variety of needs, including:
- Low pressure drop for a given efficiency for electrostatically charged or mechanical filtration or a combination of the two
- Increased or gradient dust-holding / dirt-holding capacity
- Extended lifetime
- Improved dimensional stability and strength
- Enhanced processability / pleatability
- Combined molecular (gas-phase) and particulate filtration
- Increased or decreased hydrophobicity / oleophobicity
- Reduced total cost of ownership
What Are Some Common Uses of Composite Filter Media?
H&V offers a variety of composite filter media solutions for specific end-uses. Typical applications for our products include:
- Cabin air combination filters (combining particulate and molecular filtration)
