Boost-A-Break® AB Gap 3-7A Variable 230 V

Break Tank assembly with Fluid Category 5 protection by virtue of the integral Type AB air gap. The unit is supplied as a complete package on a base plate ready for installation. The primary purpose is to provide backflow protection in accordance with the new Water Regulations. The BTAB unit also boosts the water pressure for elevated areas or where a high flow rate is required  e.g. wash-down. The cistern has a screened overflow and weir, making it suitable for unorthodox applications, which require a Hygienic Type AB air gap  e.g. butchery and vegetable preparation. The unit is quiet by virtue of the centrifugal pumps, anti-vibration rubber feet and flexible stainless braided connection hoses.
Product Code: BTAB3-7A
