Technical date

Bridge Slot filter

The slots of this kind of screen are punched precisely in a flat sheet which then is rolled into a pipe. The sand and gravel can't easily block the slot because of the special bridge style design, and Bridge Slot Screens has great mechanical strength and water entering capacity. Meanwhile, Bridge Slot Screens use steel punching technology and is rolled in many ways, so they are light, cheap and easily operating.
