4,000 Litre Insulated CAT5 Type AB Air Gap Break Tank

4,000 Litre Type AB Air Gap Break Tank Cat 5 is fitted with Type AB-Air gap with weir overflow (Fluid 5), the weir overflow (Fluid 5) which is non-mechanical backflow prevention for inlets up to 50mm. Many water authorities demand that water storage tanks connected to the mains water supply have suitable measures to protect the mains from contamination. The AB Airgap is designed to prevent the inlet to become submerged and stop the water within the tank from contaminating the mains water supply should there be a backflow pressure drop in the mains.  These 4,000 litre Break Tanks are made from rotationally moulded polyethene, fitted with a cowled overflow to prevent the ingress of light into the tank and a stainless steel mesh to prevent the ingress of debris into the tank. Larger weirs can be specially made for larger inlets.
