X-Floc Dämmtechnik-Maschinen GmbH, based in Renningen near Stuttgart, has been developing blow-in machines since 1994. At that time, only blow-in machines from the USA were available in Europe, and the founders of X-Floc quickly recognised the weaknesses of these very simple machines. Since then, X-Floc has developed many innovations and design standards in the pneumatic conveyance of insulation materials, many of which have become established as state of the art. Milestones here include, for example, the convenient and advanced control options of the machines with the FFB2000-Pro radio remote control, as well as dynamic pressure control and automatic shutdown, sluice venting, advanced ergonomic standards, the compact and robust design of the machines, and the closed filling containers with strip curtains and the option of active dust extraction. Many of these innovations are part of the basic equipment of an X-Floc blowing machine. One important development goal of X-Floc has never changed: the blowing machines should be highly compatible with all blowing insulation materials available on the market (cellulose, wood fibre, mineral wool, granulates, bulk materials and composite
