Arrow Stealth Booster

Ultra-compact Domestic Cold Water Booster Pump Set with integral Automatic Bypass Valve. The unit is designed to boost pressure for tall buildings where space is limited and the mains supply is inadequate. The Arrow Stealth Booster is supplied as a complete package on a stainless steel base – the exceptionally small footprint allows the unit to be installed in a kitchen cupboard, negating the need for a plant room. The integral Bypass Valve ensures a continued mains supply (at mains pressure) in the event of power failure or maintenance. The variable speed pump, anti-vibration rubber feet and flexible stainless braided connection hoses result in the unit being extremely quiet during operation. Fast filling is achieved by a servo controlled solenoid valve with solid-state level probe control.
