Air Knives used for drying, cleaning or material removal complete their work in a two-stage process: Firstly, a high velocity air stream is intended to roll the liquid or material back, creating a standing wave at the point of shear and leaving a thin, residual layer. Secondly, as the point of impact of the imposing air flow passes over the residual layer, this layer is crushed or atomized to form minute liquid droplets which are carried away by the air stream to leave a clean, dry surface. Non-liquids are also blown away and removed in this second phase.

Air Knives can make use of temperature or convenient air pressure to offer extra evaporation, materials-setting, cooling, heating, curing or coating control ability. Each system is planned taking into consideration the exact material distinctiveness and processing requirements of the products involved .Air Knife provides clean, precise air flow for any application.
