FAQ

Q
What is the grammage (GSM) range for this aramid (Nomex) needle-punched felt filter media? What are the common specifications?
A
Our aramid needle-punched felt filter media is available in multiple specifications ranging from 300 GSM to 600 GSM. Common specifications include 450 GSM, 500 GSM, 550 GSM, etc. For applications requiring higher strength or durability, we also offer products with a basis weight ≥850 GSM.
Q
What are the primary characteristics and advantages of aramid needle-punched felt filter media?
A
Aramid needle-punched felt filter media exhibits exceptional high-temperature resistance, outstanding chemical corrosion resistance (particularly excellent alkali resistance), superior abrasion resistance, and good dimensional stability. It maintains long service life and stable filtration efficiency under high temperatures and harsh chemical environments.
Q
What is the normal continuous operating temperature for this filter material? What is its maximum instantaneous temperature tolerance?
A
Aramid needle-punched felt typically has a continuous operating temperature ≤204°C (396°F) and can withstand instantaneous temperatures of 220°C to 240°C (428°F to 460°F). Products using glass fiber backing can achieve a continuous operating temperature ≤220°C (396°F) and an instantaneous temperature of 240°C (460°F).
Q
How does aramid filter media perform against chemical corrosion?
A
Aramid fibers exhibit good acid resistance and excellent alkali resistance. However, their acid resistance is moderate, requiring caution when used in strong acids or specific chemical environments.
Q
In which industries or applications is this filter media typically used?
A
Aramid needle-punched felt filter media is widely used in high-temperature flue gas treatment across industries such as cement, steel metallurgy, chemicals, carbon black, foundry, refractories, and waste incineration. It is particularly suitable for high-temperature conditions with moderate chemical corrosion.
