An ACI blower-powered Air Knife System typically consists of the following main components – a centrifugal supply blower; appropriate ducting; and finally a suitable method of air delivery. We offer these types of Air Knives:
Stainless Steel Air Knives
Air Knives can be fabricated from stainless steel – a material that is perfectly suited for harsh or corrosive environments, in particular the food industry where cleanliness is of paramount importance.
Stainless Steel Air Knives could be Modular or Fully Welded.
Ring Air Knives
ACI ‘Ring’ Air Knives allow for circular and round product to be easily dried around their entire circumference.
‘Ring’ Air Knives are typically fabricated from Stainless Steel 304, and can be manufactured up to 750mm in diameter. They can also be produced in two separate halves when required, as this may be necessary for drying larger items such as cable and wire products where the loading process needs to be simplified. An example of where this may be particularly useful is drying continuous extrusion.
Square Air Knives
ACI has the capability of supplying multi-bladed and square air knives to industry. Fabricated from Stainless Steel 304, these air delivery solutions are particularly useful for cooling and drying square-shaped products that need processing on more than one facing side.
Chevron Air Knives
Within certain industrial drying processes, such as the drying of wide metal sheet or sheets with a lot of standing water present, ACI will supply Air Knives in a chevron style where they are proven to have some critical advantages over straight air knife designs. For example the chevron has the effect of pushing the water to product edges far more effectively and in less time than a straight air knife which in some circumstances creates a ‘bow wave’. When this occurs the overall drying effect of the air knife is severely minimised and moisture will remain on the product surface.
De-ionisation Air Knives
ACI’s blower-powered De-Ionisation Air Knives produce fast-moving ionised air which neutralises any present static electricity and simultaneously removes any contaminants present. This style of Air Knife is perfectly suited to clean plastic parts, mouldings, glass sheets, automobiles and other large objects – both removing the dust and eliminating the static electricity to prevent re-attraction
