No-drip internal-mix atomizing spray nozzles work in the same way standard atomizing nozzles do but have the added benefit of positively stopping liquid flow when compressed air is shut off. The nozzles mix liquid and air inside the nozzle and produce the finest atomization of liquids up to 300 centipoise. When the compressed air supply is shut off, the no-drip nozzle positively seals off the flow of liquid, eliminating the possibility of drips. The patented no-drip design requires no additional airline. Ideal where no post-spray drip is permissible, the nozzles are available in four patterns: narrow angle round, wide angle round, flat fan and 360-degree hollow circular pattern.
