GlassFiber Needle Felt
Glassfiber needle felt is a good choice for gas filtration applications. Glassfiber needle feltis a specially engineered fiberglass feltmedia designed to meet the most demandingparticulate filtration applications.
Glassfiber Features:
Glassfiber is high-speed, high efficient and high-temperature resistant filtermaterial.In compare with other high temperature resistance felts, glassfiber felt is cheaper and could resist higher temperature, but due to high resistance, filtering efficiency is lower.
Advantages:
- High temperature resistance
- Excellent dimensional stability and low shrinkage rate
- High breaking strength
- High cost performance ratio, low price compared to other high temperature filter felt
Disadvantages
- Easy breaking and un-extendable
