Description
The BTAF (A) is designed to overcome the need for high flow rates without the compromise on space. Still able to fit through a standard doorway, and not requiring a full-size plant room, the high duty range boasts an impressive 3.7 litres/sec. at 3 bar to 8 bar dependent on model. The unit has 100 litres of stored water, and a tank that is flooded from 3 number 1” Solenoids, to maintain the flow. The primary purpose is to boost water pressure to elevated areas, where the mains supply is inadequate for these needs. The set is approved for drinking (wholesome) water since it has the required screened overflow and vent, conforming to G16.13. The unit is quiet by virtue of inverter-controlled pumps, anti-vibration feet and flexible stainless braided connection hoses.
