detalyadong pagpapakilala

The LFN high-flow pleated Filter Cartridge uses a deep-layer fine polypropylene fiber membrane as the filter media, with a diameter of 6.5'/165mm.

The large diameter increases the effective filtration area, reducing the requirements for filter size and the number of filter cartridges during use.

This design significantly reduces equipment and labor costs, and is more convenient to operate. It features internal PP frame support and a single opening.

The filter is specially designed with an outside-to-inside liquid flow direction to ensure that all pollutant particles are intercepted on the outside of the filter element, making it widely applicable.

It is widely used in different fields.
