Mainsboost iBoost CAT 5 water pressure and flow boosting systems feature a weir overflow making them suitable for use in commercial applications where the risk of back flow contamination from Category 5 fluids exists.

The Mainsboost MB 450SV features a nominal vessel size of 450 litres and a pressurised water holding capacity of approximately 248 litres.

Mainsboost Insulation Jackets are tailor made to ensure a perfect fit and protect Mainsboost vessels from extremes of hot and cold temperatures, ensuring the potable water stored within the Mainsboost vessel is at the perfect temperature.

The 2 vessel Mainsboost 450 litre vertical steel system with 28 mm connections are installed directly onto the incoming water supply and under mains pressure fills with water. When the chamber is full the unit reaches a state of pressure equilibrium. The Mainsboost system now has a volume of pressurised water ready for distribution throughout the property.

Where vertical space is not an issue the Mainsboost vessel mounted Charger pump may be the answer. Mainsboost vessel mounted Charger pumps offers the same performance benefits as the wall mounted variant and can be used in conjunction with Mainsboost Steel vessels.

These fully integrated systems combine a 200 litre cold water storage tank and a high performance, multistage pump to overcome restricted water flow and insufficient pressure.
