Ultra-Thin Filter Fabric
With thickness similar to filter paper, this fabric provides higher flow and is more flexible than felt. It’s often used to filter water, light oil, and water soluble and synthetic coolants in metal polishing, grinding, and finishing applications. This fabric is also good for filtering air and petroleum.
Rayon/polyester fabric is commonly used in coolant applications.
Polyester fabric is 100% polyester for greater strength than rayon/polyester.

Filter Felt
Remove particles from water, organic solvents, petroleum, and weak alkalies.
Select felt based on the size of the particles you wish to remove. For example, the particle size of flour is about 100 microns and talcum powder is about 10 microns. View more information on particle size in microns.

Chemical-Resistant Filter Felt
This felt offers better resistance to acids and alkalies than standard filter felt.
Select felt based on the size of the particles you wish to remove. For example, the particle size of flour is about 100 microns and talcum powder is about 10 microns. View more information on particle size in microns.
Filter Paper Discs
Often used in laboratory testing, these discs are designed to capture tiny particles from fluids.
Pleated discs have a large surface area, which retains more particles than flat discs.
Cellulose discs are good for general purpose filtering, where exceptional strength or chemical resistance is not needed.
Fiberglass discs remain strong even when wet. Use them to filter large amounts of solids, or in applications with a high flow rate. They are autoclavable, meaning they can be sterilized with steam.
PTFE discs hold up to acids and solvents, and can be used with a wider range of chemicals than fiberglass and cellulose.

Ultra-High-Temperature Quartz Glass Filter Wool
Form unique shapes inside filters to sift corrosive liquids and gases at temperatures up to 1900°F. Because this wool is flexible, it’s good for use inside tubing and other lab equipment that doesn’t support flat filters. It won’t expand or contract when used with harsh materials, such as acids and acidic gases; however, hydrofluoric and phosphoric acids will eat away at the quartz material. Unlike natural quartz, this quartz is more than 99.95% pure, which means it won’t let in contaminants and is useful in applications where maintaining purity is crucial.
