Air Knives for Blowers

Air Knife
Use with a blower for high-speed airflow at low pressure. Air knives create a sheet of high-velocity air for drying and cooling parts, wiping conveyor belts, controlling coating depth, and blowing liquids, chips, and dust from equipment.
A complete system requires a pipe nipple reducer, flexible duct hose, and hose clamps (all sold separately). Connect your blower to the duct hose using the reducer and clamps, and then attach the air knife.
