| you are: Colouring by pneumatic dispersion
The chambers of periodic action named sometimes deadlock, are applied mainly in individual and small-scale manufacture, in mass manufacture use chambers of continuous action - checkpoints.
In the chambers described above the painted product partially blocks a crack for otsosa air that worsens the ventilation, besides, some part of a painting dust gets from time to time on the worker. Therefore when for colouring of large-sized products it is necessary for worker to be inside, chambers of other design are applied.
Large-sized products - machine tools, trolley buses, buses paint with the help raspylitelnyh chambers in which polluted air is sucked away through lattices in a floor, and fresh and pure air moves through an aperture in a ceiling. The chamber is equipped by elevating platforms, using with which the worker can freely paint the top parts of a product and bypass it from different directions. The stream of fresh air at movement from top to down washes the worker, leaves through a trellised floor of the chamber and carries away a dust from a paint.
Under a trellised floor there is a bath with water in which heavy particles of a paint are besieged. Hydrofilters definitively clear air. In the described chamber there is also a douche of walls by water from atomizers. At douche by water the paint which has settled on walls, is washed off in a bath.
Feature of a design of the chamber consists that it has no top overlapping. Fresh air arrives from above through a forced ventilation box, the painting dust is sucked away through lattices in a floor.
