Product Description
NonStop®
Bowsmith NonStop Series Emitters incorporate a series of flexible silicone orifices. The silicone is highly resistant to chlorine and most commonly used fertilizers. Each orifice retains its shape and performance for years.
Bowsmith’s famed NonStop emitter family, is known worldwide for unmatched performance under the most challenging conditions. The “NonStop” design features the exclusive Continuous Flushing Action, which continually flushes the emitter of slime and small particles while the emitter is in operation. This means fewer clogs and lower maintenance requirements.
Drip Emitters
Product Description The Bowsmith NonStop emitter design, patented in 1974, is based on a simple unique principle found in no other emitter. This Pressure Cascade Principle permits the emitter to tolerate large amounts of suspended solids in irrigation water, without clogging and without the need for fine-mesh screens. How filter it works
1 Under normal conditions, there is a slight pres-
sure differential across each orifice in the silicone diaphragm.

For over 40 years, millions of Bowsmith NonStop emitters have demonstrated that the unique NonStop Continuous 4.0 Self-Cleaning Action ( Pressure (15.1) Cascade Principle) really works, even under conditions that would quickly clog ordinary emitters. With only 30-mesh filtration (recommended minimum), Bowsmith NonStop emitters have operated successfully with water containing heavy 3.0concentrations of sand, silt, iron bacteria “slime”, calcium carbonates, even algae and moss.
