A device for formation of an air envelope of the torch of paint from the paint sprayer is proposed, which contains internal and external diffusers, which are installed with possibility of removal on paint supply the channel of paint sprayer on common axle and form an annular recess, which passes into the annular nozzle of Laval with expandable annular socket. Annular recess for supply of air into the annular nozzle of Laval is a dual chamber, and internal diffuser is equipped with an extender of the channel of supply of paint fixed on it by one with regular paint-spraying head located at its second end, moreover, the divergence angle of external diffuser is greater than the divergence angle of internal diffuser, and both divergence angles of diffusers are commensurable with the angle atomization of the torch of paint.
