The nozzle easily handles dirty, contaminated liquids even without filtration system. It has a robust, yet reliable design with vanes locked in place.

Conventional low flow whirl nozzles use a whirl-vane element machined from bar stock and have a variety of slots or holes strategically oriented to produce a vortex. Typically, the edges of these critically toleranced features are sharp and therefore, subject to accelerated corrosion rates. Corrosion of these surfaces removes material and this, in turn, affects spray performance. The smooth surfaces of the s-shaped MaxiPass L vane are less subject to such corrosion, and are made from 316 stainless steel, even in nozzles with brass bodies, extending nozzle life.
