Standard Angle Spray - WhirlJet® AX Hollow Cone Spray Nozzle @ 40 psi (3 bar); Standard hollow cone WhirlJet® spray nozzles feature a hollow cone spray pattern with a ring-shaped impact area.

WhirlJet® nozzles also feature large and unobstructed flow passages, which minimize or eliminate clogging.; Use WhirlJet® hollow cone spray nozzles in a wide variety of applications - brine spraying, chemical processing, dust control, evaporative cooling in spray ponds and cooling towers, gas scrubbing, washing and cooling, metal treating, product degreasing, water aerating and water cooling.
