Following the introduction of ‘ring’ air knives, Air Control Industries has the additional capability of supplying square and multi-bladed air knives to industry. Typically fabricated from Stainless Steel 304, these air delivery solutions are particularly useful for cooling and drying products that will need processing on more than one facing side.
A recent example of how square air knives were applied involved a blower-driven drying system supplied to improve the manufacturing process of concrete railway sleepers. The ‘quadrangular’ air knife was able to improve the bonding process where the sleepers are attached to protective plastic jackets for anti-vibration purposes and easy replacement. The added flexible nozzle connections, fed from the air knife plenum, allows air to be directed at some of the smaller blind holes present on the sleeper bodies.
