NonStop® - Bowsmith

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.

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.
