Fresco’s range of air knives are designed to remove loose packaging material, dust and features etc. from 25kg and 50kg bags. The top and bottom air knives blast high velocity air on to the bags’ surface removing foreign matter as they pass on a continuous basis. The dislodged material is collected via a dust collection system and easy slide removable tray. Inlet and outlet strip curtains enclose the internals of the air knife.
For added material removal a pair of rotating brushes can be fitted providing active surface brushing prior to passing the air knives.
Filter selection is based on the product type and is either cartridge or bag type with normal filtration efficiency of 99.999% on 0.5-micron material. Filter access is provided through a side access hatch with removal cell plate, options from the clean or dirty side of the plenum are also available.
Filters are cleaned via the continuous duty reverse pulse cleaning system which is designed for continuous online and offline operation.
An optional rotational brush set can be incorporated to assist with the dislodgment of foreign materials that may have settled on the top surface of the bag during extended storage.
