UNMTM High Efficiency Filter Paper for Fan Filter Unit
It created a high-efficiency, hydrophobic filter medium with a filtration accuracy of up to 99.99997%, which can effectively intercept particles, water vapor and harmful gases in the air.
Acid & Alkali Resistance
Superior chemical resistance, superior resistance to acids (as hydrofluoric acid HF), bases and organic solvents.
High Porosity, Good Hydrophobicity & Air Permeability
Super waterproof, superior mechanical strength and durability.
Low Wind Resistance & High Dust Holding Capacity
This material has a multi-layer cascade structure, it can achieve a better balance between wind resistance and interception rate, and greatly increase the dust holding capacity of the filter media.
Overview
A fan filter unit (FFU) is a type of motorized air filtering equipment. It is used to supply purified air to cleanrooms, laboratories, medical facilities or microenvironments by removing harmful airborne particles from recirculating air. The units are installed within the system's ceiling or floor grid. Large cleanrooms require a proportionally large number of FFUs, which in some cases may range from several hundred to several thousand. Units often contain their own pre-filter, HEPA filter and internally controllable fan air distribution.
Our product created a high-efficiency, hydrophobic filter medium with a filtration accuracy of up to 99.99997%, which can effectively intercept particles, water vapor and harmful gases in the air. It can fully meet the processing and purification requirements of precision electronic products such as semiconductor chips.
Electron Micrograph
The air filters which made by our material can meet EN 1822-2019, GB/T 13554, ISO 29463, IEST-RP-CCOO1, etc.
Product Offerings
Through R&D and extensive field testing, we’ve developed a portfolio of Unm filter media designed to fit many air purification applications. We also offer membrane discs in custom sizes for diverse applications.
