Usages: it can be used with deep well pump to dive the water pump, also can be used in the water-treating equipment, the environmental protection, the sea water transforms into the industrial water and life use water desalination treatment, running water treatment, water softening treatment; the petroleum industry, the petroleum product terminal filters; and the chemical acid, the alkali liquid filters, the ethyl alcohol and the organic solution recycling filters.

Features:
1. Screens with high open area are more suitable for the construction of high-quality water wells, oil wells and gas wells.
2. Low cost operation. Screens with high open area shall favor groundwater infiltration. Abundant water shall reduce the water levels down, thus to save energy consumption.
3. Reduce the abrasion of the pump. Under the same condition, high open area can make the speed of groundwater entering into the screen much slower than any other filtration apparatus, which will avoid sands entering into screen because of high pressure, thus reduce the abrasion of the pump.
4. Extend the life span of well. Comparatively, groundwater entering into screen with higher open area is much easier than the entering into lower open area screen. The slow water flow shall extend the life span of the well.
