Features:

1. A continuous slot opening which significantly increases the available open area, thus providing greater access to the water

bearing zone.

2. Under the same condition, high open area can make the speed of groundwater’s entering into the screen much slower than

any other filtration apparatus, which will avoid sand’s entering into screen because of high pressure, thus reduce the abrasion

of the pump.

3. Our product have good character of anti-acid,anti-alkali and anti-corrosion,it can adapt to the oil well’s special demand.the crack won’t become bigger because of corrosion.it has good stability.

4. They have the features of easy backwashing, durable in use,safety and reliability as well as low comprehensive cost.

Inspection:

BV,SGS,ROHS etc.

Packing:

Generally speaking.the inside is packed by plastic membrane,the outside is packed by non-woven fabrics,then we bundled them by steel strip.also we can pack them according to customers’demands.
