Sky filter for painting booths

The sky cabin filters for oven cabinets for industry and bodywork are resin-coated non-woven fabrics of very fine polyester fibers, needled and moistened with adhesive resin

The air outlet side of the ceiling filter is finished with mesh and a protective anti-lint layer
The resulting structure is a random arrangement of the fibers with progressive density in the direction of the air flow

The primary function of the sky filter

The ceiling filter removes solid particles from the air entering the spray booth plenum so that the finishing process is flawless

The first cause of defects in painting operations is airborne dust
The dust that is deposited on the component to be painted can cause creepings and defects visible to the naked eye in the form of raised dots

A good sky filter limits the entry of dust from the outside, changing the sky filter is one of the first solutions to be implemented in case of defects

The top filter must be very efficient and have a good accumulation, these characteristics guarantee filter life and cleanliness of the air entering the oven cabin.

Other functions of the cab head filter 

In painting systems, the Cielo filter has the dual function of making the air coming from the plenum uniform and reducing the particulate matter present in the air inlet to the booths

For this reason the top filter must have a high pressure drop, contrary to what is required of other filters

The high pressure drop allows to distribute the incoming air evenly and limit the formation of vortices in the oven cabins

A good sky filter is the basis of a quality finishing process; the Cielo filter must be the best in the range in terms of weight, progressive structure, adhesive oiled surface, support net on the air outlet side
