PP pleated filters, fully known as Polypropylene (PP) pleated filters, are a widely used air pre-filtering equipment in the food and beverage production sectors. They are typically made of polypropylene material, which is renowned for its excellent chemical stability and thermal stability, capable of resisting most common chemical substances encountered in food and beverage production processes. Polypropylene also boasts good thermal resistance, allowing for stable operation in high-temperature environments, while maintaining superior filtration capabilities.
1.For food and beverage air pre-filtration
* The filter cartridge features a pleated design, which increases the filtering area, resulting in higher filtration efficiency per unit volume. It also reduces the thickness of the cartridge, making it easier to install and replace;
* The pleated structure also means that the cartridge occupies less space for the same filtering area, making it suitable for food and beverage production environments with limited space;
* PP pleated filters have good durability and a long service life, reducing the need for frequent cartridge replacement and lowering maintenance costs. Additionally, their easy-to-clean and regenerative properties can extend the service life of the cartridges in certain situations;
* With a variety of installation methods and size options, they can adapt to the needs of different food and beverage production facilities, ensuring consistent and efficient air filtration;
* 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;
