Self-Sealing Filter FAQ Guide

What is the Working Principles of Self-Sealing Filter?

 

In the dry conditions, the polymer elastomer in self-sealing filter will not expand, so the air and other gas can pass through smoothly with high permeability. However, once self-sealing filter contacting water, the polymer elastomer will expands instantly and rapidly, blocking the pores of sintered PE filter, when the pathway closes, the water or liquid cannot pass through, hence the filter can be self-sealed.

With advanced sealing technology, Filson sintered PE filter can complete self-sealing in a short time and able to withstand high water pressure.

What Types of Medical Applications Use Self-Sealing Filter?

Self-sealing filter has wide range of applications in medical and biological fields, such as blood transfusions, dialysis, drug delivery, medical imaging, etc.

Can Self-Sealing Filter be Used With Different Types of Fluids?

Can Self-Sealing Filter be Used With Different Types of Fluids

With outstanding resistance to most chemicals and corrosion, Filson self-sealing filter has stable performance in any harsh conditions and can be used in wide range of fluids.

Can Self-Sealing Filter be Recycled?

Can Self-Sealing Filter be Recycled

It depends on the specific materials used in the filter and the recycling facilities available in customers’ area. Some self-sealing filter may be recyclable, while others may need to be disposed of as medical waste.
