Product Features and Benefits
Extremely strong corrosion resistance
Polytetrafluoroethylene is one of the most chemically stable materials known to date, and can work for a long time in strong acids, alkalis, oxidizers, chlorine and other complex gases, IDEAL FOR PTFE DEMISTER APPLICATIONS.
High purity, no pollution
The material itself does not release any impurities, suitable for high-purity electronic gases, pharmaceutical aseptic environments and other occasions where the cleanliness of the gas is required to be extremely high.
Strong hydrophobicity, not easy to clog
Teflon screen structure is hydrophobic, even in high humidity conditions can maintain good air permeability and liquid droplet separation performance, not easy to scale or clogging.
High temperature resistance and anti-aging
It can be used for a long time under 260°C, and can withstand higher temperatures for a short period of time, with excellent aging resistance and thermal stability.
Lightweight and easy to install
Compared with metal wire mesh, PTFE mesh is lighter and easier to install, dismantle and maintain on site, reducing labor costs.

FAQ
Yes. PTFE does not react with almost any chemical substance and is suitable for working conditions with extremely high acid and alkali concentrations or strong oxidants. Stainless steel is prone to corrosion failure under such conditions, while PTFE is stable for a long time.
LiandaFiltration's PTFE wire mesh demisters can operate stably at 260°C, which is within the temperature range required in most tower gas-liquid separation processes.
No. PTFE itself is a high-purity material that does not release any impurities and is non-toxic and odorless. It is suitable for use in high-purity fields such as pharmaceuticals, food, and electronics.
Under standard operating conditions, the PTFE demister can operate stably for more than 3 to 5 years, with almost no need for frequent replacement and no need for anti-corrosion treatment, reducing maintenance costs.
Of course. LiandaFiltration can customize the PTFE mist eliminator solution according to the customer's tower structure size and process parameters to ensure installation and operation effect.
