CPP Series PP Spun Bonded Filter Cartridges with Furry Surface


On the basis of normal PP spun bonded filter cartridges, Hongtek developed a new type CPP Series PP Spun Bonded Filter Cartridges with Cottony Surface, which adopted advanced thermally bonded techniques to meet customers' requirements. PP spun bonded cartridges are manufactured of 100% FDA approved polypropylene, without surfactants, binders and adhesives. With hairy surface treatment, spun bonded cartridges have larger dirt holding capability and strong anti-pressure ability. PP spun bonded filter cartridges have consistent performance with a 99.9%(Beta 1000) efficiency rating during long service life and are widely used for many important industrial filtration applications.

Working Principle of PP Spun Bonded Filter Cartridges

● The drawing is the working principle of layers structure depth pp spun bonded filters

● Layers filtration keep pp spun bonded filters high flow rate, good filtration efficiency and long service life

● Small particles pass the outer layers, then filtered by inner layers wich made of fine fiber and high precision

● Large particles are hold in cottony surface layers of pp spun bonded cartridges which are constructed by coarse fine

Installation of PP Spun Bonded Filter CartridgesInstallation_Absolute_Melt_Blown_Filters.jpg

● Hongtek brand depth pp spun bonded filters used for pre RO water filtration

● After used pp spun filters compare with before used can apparent know the good efficiency filtration

● The central of pp spun bonded cartridges are still no polluted, so that keep liquid clear after filtration

● No fiber drop out, high dirt holding, low pressure drop, high flow rate and high pressure resisting capability

● High quality and reasonable price pp spun filter cartridges increase of longer service life and save much cost
