Large flow water filter:
The area design of the filter is only on the lower line and not on the line. That is to say, the increase in area within the specified parameters has many advantages for life：
The large filtration area of the large-flow water filter has the advantages of small footprint, long life, high filtration efficiency, and convenient manual replacement, and has been widely promoted.
Reverse osmosis RO system pre-filtration, purification of various process water：
Power plant: condensate, stator cooling water (starting filter 20μ, working filter 5μ)
General industry: various fluids, process water, condensate, cooling water, wastewater treatment, etc.
Microelectronics industry: deionized water pre-filtration
Food and beverage industry: process water, etc. (pool, children playing with water)
Chemical industry: various chemicals, alkalis, solvents, quench water, salt water and other chemicals
Water filtration is divided into five levels:
Pre-filtration: melt-blown filtration, wire-wound filtration, high flow rate, sintering filtration, etc.
Microfiltration (MF): Folding filter 10′′ per section (0.5-0.6M2)
Ultrafiltration (UF): hollow fiber, membrane filtration.
Nanofiltration (NF): nanoscale
Reverse osmosis (RO): Dow filter.
At present, large-flow water filtration is a product of two large companies.
Pall: With a handle, it is the first water filter designed from the inside to the outside.

3M company：
3M's large-flow water filter has a handle at the end, which is filtered from the outside to the inside. There is a guide strip on the mating head.
After the guide is pressed in the installation, the rotation is locked.
