Product Description

Expanded metal filters also known as expanded mesh filter cylinders, the filters are made of expanded metal sheets, the commonly types include longitudinal welded pipes and spiral welded pipes. Expanded metal are being slit and stretched by punching machines, forming into various hole patterns, this kind of products has sturdy construction and hole shape can keep not deformed for long time, so that expanded metal cylindrical filters is more rigid and solid than the wire mesh filter tubes.

YILIDA can offer expanded metal filters in standard specifications, the size range from 10 mm to 300 mm, and manufacture length up to 3 m. The expanded mesh tube is commonly constructed with materials of aluminum, galvanized steel or stainless steel.

Applications
The expanded metal sheet can be used as support screen of the filter elements, such as dust filters and air filters, and also can be used in Y strainer for filtering solid, water and other goods.

ASK & ANSWER

1. How is expanded metal useful in the manufacturing of HEPA filters?

Expanded metal is the outside screen that protects the filter media while allowing air to pass through the filter at a predetermined air flow rate. 

1. What patterns and sizes of expanded metal is typically used in HEPA filters?

The expanded metal pattern for HEPA filters is typically .250" SWD x .500" LWD allowing for a 72% - 75% air flow rate.  The expanded metal is cut to the exact size of each HEPA Filter and is then powder coated white to an industry standard used internationally.

1. Where are HEPA filters used?

There are many applications for HEPA filters including:

1. Medical - hospitals and medical office applications require a safe and sterile environment
2. Vacuum Cleaners - used to pick up small particles and dust
3. HVAC - to remove particles form the air in residential, commercial and vehicles
4. Airlines - to reduce the spread of pathogens and viruses in re-circulated air
5. Cleanroom - when dust and particles cannot be tolerated due to industrial or research processes
6. Air Purifiers - reduce the amount of airborne viruses within homes and offices
