Actually, it's a very good idea.
Industrial air knives direct air flow toward a product and use the air’s velocity for product drying, cleaning, coating and cooling in many manufacturing and packaging plants. In their most simplistic form, holes are drilled into pipes. Involutes or air amplifier designs are used in more advanced systems.
In either case, these applications require high air velocities but not high pressure.
While compressors are commonly used for air knife process applications, they are not the most energy efficient means when compared with SCB super centrifugal blowers.
A significant amount of energy is required to compress air to pressures of 5.52 – 7.58 bar before it is stored, dried and filtered.
However, SCB super centrifugal air blower is only pressurizing the air to 0.21 – 0.41 bar – mainly to overcome friction losses in the supply piping and through the air knife orifice – and this air does not require storage or further drying because of the low compression ratios.
