Point-of-Use (POU) filters are manufactured in a state of the art Class 100 Cleanroom using an ISO 9001 Certified Quality System. The filters are precision welded in a specially designed glove box with atmosphere purification. A deionized water flush, followed by a high pressure, 0.003μm filtered nitrogen flush removes particles and prevents particle shedding.
Our POU filters are vacuum dried to less than 10ppb moisture as needed and the organics are less than 10ppb THC. Particle free, chemically clean, organic free handling and bagging of the POU filters maximizes the out of-package cleanliness for installation in the most demanding microelectronics applications. Exceeding the high purity gas handling filtration requirements for semiconductor processing, Porvair's high quality products are extensively tested to insure that they meet the critical filtration efficiency, precise flow control and safety requirements for gas delivery systems in semiconductor manufacturing.

Features and benefits
- 100% leak checked for safety
To prevent exposure to flammable, corrosive, toxic and pyrophoric process gases, the filter housings are 100% Helium leak checked to greater than 1x10-9 atm scc/second.
- Corrosion resistance
Electro polished to a 5Ra surface finish to prevent corrosion. The wetted surfaces are electro polished to enhance the Chrome to Iron ratio on the surface layer, so the occurrence of corrosion generated particles is minimized.
- Particle free manufacturing
Extensive cleaning and flushing with deionized water and high pressure Nitrogen in a Class 100 Cleanroom eliminates particles.
- Extremely fine filtration media
Filter efficiency rated at 9 LRV for 0.003μm particles per SEMI F38 and ISO 12500 test methods, will remove any corrosion-generated particles and particles generated from moving parts such as pressure regulators, valves and MFCs used in the gas delivery systems.
- Mechanical strength
GasPro™ filter media is tested to insure superior service in manufacturing processes and for tools that often utilize high gas pressure and more rugged service environments.
- Exceeds standards
Porvair Filtration Group meets industry standards set by organizations such as the Semiconductor Equipment and Materials International and is a SEMI Corporate Member.
