The Rigid Manta Ray is a special weir suction head designed for oil recovery. The skimmer is suitable for thin oil slicks under relatively calm conditions where small debris is present in e.g. lakes and slow moving rivers.
The Manta Ray is a half-moon shaped flat suction head with several thin suction channels. The skimmer's top surface can be quickly opened while in operation to clear straw or small debris and closed to return to use.
