Steel Wire Cloth Discs

These discs are die cut to an exact diameter with smooth edges for use in tube, pipe, and duct. They are made of steel, which has excellent strength and good wear resistance. They are good for use with abrasive materials in noncorrosive applications and are often used to filter hydraulic oil.

Porous Stainless Steel Discs

Also known as sintered filters and frits, these discs have tiny holes that trap very small particles. Discs are often used in laboratories and gas-bubbling applications (sparging). They’re made of 316L stainless steel for excellent corrosion and abrasion resistance.

Select discs based on the size of the particles you wish to remove. For example, the particle size of talcum is about 10 microns. View more information on particle size in microns.

Filter Paper Discs

Disc

Pleated Disc

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.

Porous PTFE Adhesive-Back Discs

Color: White
Maximum Temperature: 250° F

Stick these discs onto breather and other circular vents to guard against water and dirt without obstructing flow. Often used in the electronic and automotive industries, they have very small holes so air, gas, and vapor can still pass through. These discs are made of PTFE to wick water away. They also won’t break down from most chemicals, except alkali metal and high-temperature fluorinated agents.

IP rated except for their adhesive, all seal out dust and stand up to some submersion. IP65-rated discs also handle low-pressure washdowns, while IP66-rated discs withstand high-pressure washdowns.
