5μm 20" PP Melt Blown Filter Cartridges For Water Prefiltration
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.

General Description of Water Prefiltration:
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.
Application of Water Prefiltration:
1.Security filtration
2.Clarification filtration
Features and Benefits of Water Prefiltration:
* 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;
