Description of Water Prefiltration
WECHANFIB polypropylene melt-blown filter adopts a new process, so that the whole filter has a very hard mechanical properties, the pressure resistance is more than 2 times that of ordinary melt-blown filter, and can be applied to some high viscosity and high solid content of the feed liquid. The process of melt-blowing makes it have a high contaminant capacity and can withstand more impurities. It has better good effect and low resistance to filtration of granular materials, such as metal paint.

Melting spray filters are a highly efficient filtering medium widely applied in air purification, water treatment, industrial filtration, and other fields. These filters are typically made from materials such as polypropylene (PP), polytetrafluoroethylene (PTFE), or other high molecular materials, which are known for their excellent chemical stability and thermal stability.
1.Security filtration
2.Clarification filtration
* Good chemical and thermal stability;
* Effective retention of particles, bacteria, viruses, and other impurities in air or liquid;
* To enhance filtration efficiency and dust-holding capacity, melting spray filters usually adopt a multi-layer structural design. Each layer of filter material has different pore sizes, forming a gradient filtration to further improve the filtration effect;
* 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;
