Copa - Cyclone Brochure

Jacopa’s Copa cyclone is a non-powered, self-cleaning storm screen, developed in partnership with United Utilities. The Copa cyclone’s unique design eliminates the need for an external power supply and mechanical cleaning of the screen’s surface. The Copa cyclone does not start operating until the water level reaches the shaft level. An internal baffle creates an overflow weir, directing flows onto the internal vanes. The vanes are attached to the aperture drum and cause the drum to rotate. The internal baffle extends from the 3 o’clock position to the 12 o’clock position. This only allows flows to enter the drum when water levels are above the 3 o’clock weir level.
