Cellulose is among the most commonly used fibers in filtration media. This versatile, proven, and cost-effective material is made from renewable resources and compatible with a multitude of filter production processes, such as embossing, corrugating, and pleating.
What Is Cellulose Filter Media?
Similar to traditional papermaking, cellulose media is manufactured using a wetlaid process. The result is a filtration media platform suitable for a broad range of filtration applications. Cellulose filter media can be made from pure cellulose fibers or cellulose fibers mixed with synthetic fibers or glass fibers for enhanced properties. It serves as a versatile filtration solution that functions by trapping contaminants and other particles within a matrix of fibers.
There are different grades of cellulose filter media designed to meet application-specific requirements. Grades are formulated from different combinations of fibers and resin systems, each providing different physical properties, chemical resistance, filtration efficiency, pressure drop, and flow characteristics. While each grade may differ in its capability and composition, all cellulose filter media contain resin and cellulose fibers.
Cellulose filtration media offers a host of benefits, including:
- Renewable fiber sources
- High strength and durability
- Large surface area
- Chemical stability
- Temperature stability
- Strong adhesion to glass or meltblown layers
- Good value
What Are Some Common Uses of Cellulose Filter Media?
Cellulose filter media is widely used in a range of applications. Each product platform has been highly engineered to optimize fiber content, structure, resin chemistry, and other characteristics. Common applications for cellulose media are:
- Engine air intake filters
- Gas turbine filtration
- Fuel and oil filtration
- Coalescing filters
- Hydraulic filters
- Process liquid operations
