Pleated Perforated cardboard filter for industrial spray booths belong to the category of disposable systems. They are constituted by two layers of cardboard, perforated and pleated, glued together in such a way to create “V”shaped separation cells.
In each of these cells, the holes position within the cell determines a Venturi effect or cyclone which causes the paint particles to deposit at the bottom of the cell. The high efficiency in the separation comes from this Venturi effect where the inertia of the particles is combined with important local variations in speed and direction within the cell itself.
The very long lifetime of pleated cardboard separators comes from its large inner cell volume available for the paint articles within the cell. According to the sprayed product type, impressing results can be achieved: a separation ratio reaching or even over passing 98% and a lifetime multiplied by 5 or 6 in comparison to fibre filters. Moreover, surface clogging does no longer appera, even with dense and sticky products.
It’s geometric design promotes distribution of The frontal speed
Low resistance to air, maximum filter efficiency
Frontal speed 0.5-1 meter per second
Lasts up to six time longer than any other filter type
All type of dry and wet booths can be converted to use pleated cardboard filters
