The floor conveyorised painting or Batch type painting line will have a downdraft dry type booth either because of low consumption of paint or due to environmental aspects.
The modular constructed will have the civil pit underneath and a pleated washable paint arresting filters will be fitted in the bottom. This will have a provision for regular replacement and maintenance. These filters are going to be a consumable. A differential manometer will be provided to know the percentage of clogging in the filters.
The suction will be effective in the downwards and operator need to face the gun always towards the bottom during coating. If the component calls for all sides coating, the operator can go around the object and coat or otherwise, if the size of the booth is big, then two operators can simultaneously do the painting.
The booth can be made pressurized (dust proof coating system), by pushing an external air from Air Supply Unit (ASU).
