WB-Coffin 320 Mini3 Variable Speed 2206210

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 Polytank 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, including garages, cupboards, and plant rooms.

For added convenience, the tank is supplied pre-fitted with a By-law 30 kit and ½” ball valve, and all interconnecting pipework is included as standard, ensuring installation is swift, clean, and straightforward. Energy-efficient operation is delivered through the Mini3’s advanced variable-speed control, providing smooth, stable pressure while helping to minimise running costs.
