When the air passed the centrifugal blower / air blower and get into the air knife, the 0.05 mm thickness air flow will be blowed out in a high speed, In the use of the corresponding principle and the special shape of the air knife, the air flow will be 30 to 40 times more, slowly, there will be a very thin layer of air curtain.The air knife is seperated in standard air knife and a super air knife. The Dereike brand standard air knife will be blowed out after turning 90degree, and the super air knife's air curtain is blowed out horizontal.
The Air knife performance used with the vortex pump is very prominent, it is made of aluminum alloy, stainless steel, The air knife also have plating, therefore Dereike air knife working life is much longer than the normal one, Dereike stainless steel air knife can use in high temperature and high corrosion because of the super material. The maximum air flow of the air knife is 40 times more than the ambient air, however the air consumption is only 1/5 of air suction pipe. There is no any worn in side of the air knife, in the inner gasket it is also stainless steel material.
