PCT No. PCT/SE95/00023 Sec. 371 Date Jul. 24, 1996 Sec. 102(e) Date Jul. 24, 1996 PCT Filed Jan. 13, 1995 PCT Pub. No. WO95/20438 PCT Pub. Date Aug. 3, 1995A mobile unit for applying fluids, such as paint, on large surfaces, in particular floor surfaces, comprises a number of spraying means (14) mounted in a casing (7). The spraying means are surrounded by an encircling shielding (9). The casing (7) has an opening exposed towards a fluid application surface. In the unit there is an air evacuating device (21) having the task of providing a flow of air into the interior of the casing (7) from an air gap established between the application surface and a free edge (16) of the shielding, so as to minimize the emission of particles from the unit to the surroundings in connection with the application of fluid onto the surface. |
