Fiktech B.V. products

An air knife is a compressed air-filled chamber with converging route to a controlled output slot. This provides a uniform velocity distribution across the entire length of the blade. Due to the Coanda-effect at the same time ambient air is sucked in with the primary air flow. Hereby an even more powerful secondary air flow is obtained.

The circular air knife - Fiktech AirWipe - is a simple solution to many clean elongated products from and moisture with compressed air Compressed air of up to 7 bar (R) is supplied to the inlet and is evenly distributed in the circular plenum. Through a narrow gap, the expanding air is blown at an angle of 30 º. This primary airflow moves along the Coanda-surface in the direction of the object to be cleaned. Negative pressure is created through which ambient air adds to the primary airflow. The combined airflow forms a closed ring of 360 º and cleans the exposed object / product.

As an additional support for removing dust Ionizing Bars may be applied. These bars neutralize static charge of sheets, webs and other planar materials. A High voltage generates at the tips of a static bar the required electric field. This turns the air molecules around the emitter points into positive and negative ions. Electrostatically charged material is thus neutralized, preventing dust particles from clinging.
