Powerful air blower with 3,900 m³/h for construction sites, water damage, industry and trade
The Master BL 6800 is a professional blower for high air volumes and versatile applications. With an air capacity of 3,900 m³/h, a powerful axial fan and a robust, rotationally molded plastic housing, it is ideal for building drying, water damage restoration, ventilation and air extraction.
The compact Master BL 6800 building dryer blower can be used for both blowing and suction. This allows air to be targeted into rooms, shafts or other areas, or extracted from contaminated areas. With a maximum pressure of 388 Pa, the unit is also suitable for applications where a certain amount of air resistance must be overcome.
In water damage restoration and building drying, intensive air movement is crucial. The Master BL 6800 supports drying by moving large volumes of air through the affected area. In combination with a suitable dehumidifier, it can effectively support the drying of walls, floors and other building components.
The blower is therefore a practical addition to professional dehumidifiers and building dryers. Its compact design makes it easy to position and transport on the construction site.
For controlled air flow, the Master BL 6800 can be used with a suitable Ø 305 mm PVC flexible hose. This allows air to be targetedly supplied or extracted over longer distances.
For example, the manufacturer offers a Master PVC flexible hose Ø 305 mm with a length of 7.6 m as an accessory for the BL 6800.
The BL 6800 can also be used with a suitable Master dust bag Ø 305 mm, 3 m. The dust bag is used to separate and collect solid particles from the airflow.
This makes the system suitable for, for example, light to medium construction and renovation work that generates dust. Typical applications include demolition work, sanding walls and floors, and processing terracotta or glaze. Workshops, production areas and warehouses with dust exposure can also benefit from targeted extraction.
The Master BL 6800 was developed for demanding areas of application. The rotationally molded plastic housing is stable and designed for use on construction sites and in commercial environments. At the same time, the unit remains relatively compact with dimensions of only 470 × 370 × 520 mm.
With a net weight of 14.7 kg, the blower is easy to transport and can be used flexibly in different locations.
