The WaterBoost WB-Coffin 320 Mini3 is a compact, variable-speed water boosting system engineered to overcome low water pressure or inadequate flow in domestic and light commercial applications. Designed for installations where space is limited, it provides a cost-effective solution while still delivering excellent performance, reliability, and build quality.
The system combines a robust 320-litre WRAS-approved coffin-style tank with the proven DAB Esybox Mini3 booster pump, delivering efficient and consistent pressure boosting of up to 50 litres per minute at 3 bar. This makes it an ideal choice for improving performance to showers, taps, and household appliances without the footprint or complexity of larger boosting systems.
With compact dimensions of 1650mm (L) × 610mm (W) × 500mm (H), the WB-Coffin 320 Mini3 is perfectly suited to installations where height restrictions or access limitations are key considerations. The tank is supplied pre-fitted with a By-law 30 kit and ½" ball valve, and all interconnecting pipework is included as standard. The tank carries a 5-year warranty and the DAB Esybox Mini3 a 3-year warranty.
