A Spray Booth Dry Filter DB series spray booth has no washing chamber. Instead, the fan draws overspray into a paper filter at the back of the booth. This traps the paint and allows clean air to be exhausted.
The disposable paper filter use principle of inertia separation. The overspray suffers several radical changes in direction. The paint particles, heavier than air, are projected out of the air stream. The filter have a holding capacity 3 to 7 times higher than most common mesh filters.
The filter has a long life but when it is fully laden with paint it can be removed and replaced easily.
