Fluoroplastic Porous Film for Air Filters TEMISH™ NTF9000 Series

TEMISH NTF9000 series is a high performance air filter which combines a PTFE porous membrane with excellent dust collection properties and a non-woven fabric chosen for its high performance air filtering/using advanced technology. In the semiconductor industry, higher integration and larger LCD screens create a demand for a cleaner environment, and the need for air filters with higher performance is increasing accordingly.The attention is paid to the maintenance free of the vacuum cleaner filter made of PTFE porous membrane.Because the PTFE porous membrane has the function of the dust resistance (proofness).

Features

ULPA(Ultra Low Penetration Air） grade, HEPA（High Efficiency Particulate Air） grade, and semi HEPA grade are available.
Better balance between pressure drop and dust collection efficiency compared with glass fiber filters and electrets filters.
Superior chemical resistance, moisture resistance, water resistance, dust release properties, resistance to acids (such as hydrofluoric acid), alkali, and organic solvents.
The Dust can be released easily with mechanical vibration or brushing.
No self-dusting characteristics, as glass fiber filters.
Performance does not degrade with washing.
No boron, phosphorus, or impurities.
Low pressure drop and high dust collection efficiency.
