The RH15W plaster machine has the hose pump as the conveying unit and the min. oilless air compressor as the unit supplying the compressed air. The work principle is: the materials are sucked into the hose pump. The pump conveys the material into the nozzle. At the nozzle, with the compressed air from the min. air compressor, the materials are sprayed at the work surface continuously and evenly. If needed, leveling or kneading compaction by hand.

The RH15W is suitable for pumping or plastering the materials without particle, such as slurry, coating, water-proof glue, etc.
