The PP pleated filter is equipped with top-of-the-line seals to ensure leak-free operation and maximum protection against fluid bypass. These seals are carefully selected and designed to meet the specific requirements of each filtration application.PP pleated filters are available in a variety of micron scales, giving you the flexibility to choose the most appropriate filtration level for.
1.For food and beverage air pre-filtration
* The filtration accuracy of PP pleated filter cores is typically at the micron level, capable of effectively removing pollutants such as fine dust, particulates, and oil mist from the air, ensuring that the air entering the food and beverage production line is clean and free from contamination. This, in turn, reduces the risk of equipment failure and product contamination during the production process;
* Integral support, high strength, high dirt-holding capacity and long service life;
* The flow rate of a single cartridge can reach 110m3/h;
* The filtration system is 50% smaller than the typical size system;
* Filtration efficiency up to 99.8%;
* 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;
