WaterBoost WB-Coffin 500 Mini3 Variable Speed 2207210B

The WaterBoost WB-Coffin 500 Mini3 is a complete variable-speed water boosting system engineered to overcome low water pressure or restricted flow in domestic and light commercial properties. Designed for installations where headroom is limited, the low-profile coffin format fits where upright tanks cannot — under stairs, inside cupboards, in low-ceiling garages and plant rooms — without sacrificing storage capacity. The system pairs a 500-litre WRAS-approved coffin-style tank with the DAB Esybox Mini3 variable-speed pump, delivering 50 l/min at 3 bar and a maximum delivery pressure of 5.5 bar. The pump’s intelligent inverter adjusts continuously to match demand — constant pressure to multiple outlets, lower energy use than fixed-speed alternatives. Tank dimensions 2200mm (L) × 600mm (W) × 630mm (H). Supplied pre-fitted with By-law 30 kit, ½” ball float valve and 1″ brass connection. All interconnecting pipework included as standard. 50l/min @ 3 bar 500L Tank storage 45dB(A) Ultra quiet 3yr DAB warranty WiFi · Google · Alexa WRAS tank & pump 630mm height Direct mains Pipework included 5.5 bar max
