The WaterBoost WB-Coffin 450 Mini3 is a compact, variable-speed water boosting system engineered to overcome low water pressure or restricted flow in domestic and light commercial applications. Designed for installations where space is limited, it delivers a cost-effective solution while maintaining excellent performance, reliability, and build quality.
The system combines a durable 450-litre WRAS-approved coffin-style tank with the proven DAB Esybox Mini3 booster pump, providing efficient and consistent pressure boosting of up to 50 litres per minute at 3 bar. This makes it ideal for improving water performance across showers, taps, and appliances without the complexity or footprint of larger boosting systems.
With compact dimensions of 1680mm (L) × 696mm (W) × 580mm (H), the WB-Coffin 450 Mini3 is perfectly suited to installations where height restrictions or access limitations are key considerations, such as garages, cupboards, and plant rooms. 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.
