The PP pleated filter core is used for pre-air filtration and is an efficient filtration solution. The core features a unique pleated design, which increases the filtration area, thereby enhancing the filtration efficiency per unit volume. The pleated structure allows the filter core to more effectively capture particles in the air during the filtration process, thereby improving the filtration efficiency.
1.Pharmaceutical field: pre-filtration of all kinds of injections, medicinal liquids and injection washing water, and all kinds of antimicrobials, traditional Chinese medicine injections.
2.Food industry: filtration of alcohol, beverage and drinking water.
3.Electronic industry: pre-filtration of pure water and ultra-pure water.
4.petroleum and chemical industry: filtration of all kinds of organic solvents, acids and alkalis, and filtration of oilfield injection water.
* The pleated design not only reduces the thickness of the filter core, making it easier to install and replace in confined spaces, but also saves installation space and streamlines the filter replacement process;
* With the same filtration area, the pleated filter core occupies less space, making it particularly suitable for environments with limited space such as food and beverage production. This not only improves space utilization but also simplifies equipment layout;
* The PP pleated filter core has excellent durability, with a long service life, which reduces the need for frequent filter replacements. This not only lowers maintenance costs but also minimizes downtime caused by filter changes;
* 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;
