WaterBoost CAT 5 WB-Coffin 340 Esybox Variable Speed 2206120CT5

The WaterBoost WB-Coffin 340 Esybox Cat 5 is a complete, variable-speed water boosting system that delivers the highest level of backflow protection in common use in a low-profile coffin format — fitting under stairs, inside cupboards, and in low-ceiling garages and plant rooms where an upright tank would not. The mains supply discharges into the tank through a Type AB air gap — the float valve sits above an unobstructed air gap and the cistern carries a weir overflow sized to handle the full inlet flow. Because there is a permanent physical break between the incoming mains and the stored water, the system protects against fluids up to and including Fluid Category 5 — the most hazardous category. The DAB Esybox variable-speed pump draws from the 340-litre tank, delivering a strong 80 l/min at 3 bar — enough for multiple bathrooms in simultaneous use. The intelligent inverter adjusts continuously to match demand, maintaining stable pressure across every outlet with low noise and reduced energy use. Supplied complete with weir overflow, ½” connection, 1″ brass outlet and all interconnecting pipework. WiFi via the DConnect app, Google Home and Alexa compatible. 3-year DAB warranty. Delivery typically 2 to 3 working days.
