Integrated Booster System

The MAINSBOOST MB 450SV is designed for ‘direct on mains’ systems where incoming pressure exceeds 2.5 bar, but flow rate is insufficient to meet household demand (e.g. multiple outlets running at once)

The unit features a nominal vessel size of 450 litres and a pressurised cold water storage capacity of approximately 248 litres.

Each unit is supplied with the unique compact MAINSBOOST Monobloc 22/28mm Upstream Kit (USK) as standard which significantly simplifies installation.

Built to last, the vessel is constructed from an epoxy-coated steel body and a durable virgin butyl diaphragm for long-term performance.
