Entegris filters Wafergard series precision filtration gas filters

The Wafergard series of Entegris filters is a series of high-performance gas filters, mainly used in semiconductors, photovoltaics and other fields, with high-precision filtration, high flow and other characteristics. The following is a detailed introduction:

Product Features

High-precision filtration: It can provide particle filtration with a precision of 0.0015 microns or even higher, which can effectively remove tiny particle impurities in the gas, ensure that the gas entering the process reaches ultra-high purity, and meet the strict requirements of high-tech industries such as semiconductors for process gases.

High flow design: Some models can achieve higher process gas flux while ensuring high-precision filtration, which can improve production efficiency and meet the process requirements of large-scale integrated circuit manufacturing and other processes with high gas flow requirements.

Compact design: Surface mount filters such as Wafergard C-seal and W-seal have a small footprint, which can save space on the gas panel and help improve the integration and space utilization of the equipment.

Good compatibility: It has excellent compatibility with various semiconductor process gases such as inert gases, hydride gases and reactive gases, ensuring stable and reliable operation in different process environments.

A variety of materials are available: Made of nickel, stainless steel, Alloy-22, PTFE and other materials to meet different chemical compatibility and process conditions.
