The invention concerns an operating unit to generate a flow of air under pressure in aerosol therapy equipment, comprising a pump group (12) powered by a motor and having a head (19), with an air inlet duct (22) complete with filter (24) and an air outlet duct (23). The pump group is enclosed in a body made up of two shells, top and bottom, (13, 14) which overlap and fit together on a transversal plane at the level of their edges. The shells forming the body receive and hold the air inlet duct (22) with filter, the air outlet duct (23) and a plate with socket and switch following their overlapping for automizable assembly of the group. |
