The Glossy surface of melt blown filter cartridge is prevent the sand from fouling into blocks. the sediment Adsorbed in the cartridge's outside, making sure the water can flow through.
It's made of the pure polypropylene, It used gradient diameter process production, the fiber formed three-dimensional Microporous structure during thermal bonding.
The out layer is loose and the innner layer is booded tight, have high sediment holding capacity, good at filtration.
Melt blown filter is suit for the all kind of filter housing, have good sealing, could make the pressure won't loss so much and increased the flow rate.
