WB-Coffin 500 Esybox Variable speed 2209310B

The WaterBoost WB-Coffin 500 Esybox is a complete variable-speed water boosting system engineered to overcome low water pressure or restricted flow in larger domestic homes and light commercial premises with high simultaneous demand. 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 variable-speed pump, delivering 80 l/min at 3 bar and a maximum delivery pressure of 6 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.
