PP Pleated Filter Cartridge for Microelectronics Air Prefiltration
5μm/20"
General Description of Microelectronics Air Prefiltration:
The PP pleated filter cores are mainly used for air pre-filtration
in the microelectronics industry. They are made of polypropylene
(PP) as the filtering material, which has good chemical and thermal
stability. It can effectively filter particles and impurities in
the air and also has certain tolerance to acids, bases, and organic
solvents.
Application of Microelectronics Air Prefiltration:
1.Prefiltration of photoresists, organic solvents, deionized water
in the microelectronics industry
Features and Benefits of Microelectronics Air Prefiltration:
* They can effectively remove pollutants such as fine dust,
particulate matter, oil mist, and others from the air, providing
good pre-treatment for subsequent precise filtration;
* Depending on the operating environment and the degree of
filtration load, the service life of the PP pleated filter cores is
approximately 3 months to 1 year, which varies depending on the
type and concentration of the pollutants being filtered;
* Regularly check the degree of contamination of the filter cores.
When the filter resistance increases significantly or the
filtration efficiency decreases, the filter cores should be
replaced in a timely manner to maintain the efficient operation of
the system;
* Strict quality control system, complete production process flow;
* Short delivery period;
* Flexible payment method: T/T, L/C, West Union, Paypal;
* Free technical support;
* Other specific sizes can be customized;
