Enclosure Louvers
Relieve heat buildup and prevent condensation from forming inside enclosures and other small spaces.
All aluminum louvers have small openings between their blades to stop bugs from getting inside your enclosure. Anodized aluminum louvers withstand corrosion better than unfinished and powder-coated aluminum louvers. They’re good for settings such as saltwater environments. Darkroom louvers have a shield on the back that blocks out light—use them where light control is a concern.

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.

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.
