Toro E-2 Emitter Data Sheet
Micro-Irrigation
Features:
• Proven Classic
E-2®Emitter
Application:
Ideal Classic®emitter for short runs and non-sloped Ag,
Nursery & Landscape applications. Suitable for seedling,
young and established plantings, were precision water
placement is required. Its take apart feature and large
open flow path, allows easy field inspection, maintenance
and greater resistance to plugging.
®
(non-pressure compensating) hydraulic design
• Available in three flow rates:
DBK04 1.0 gph (4.0 lph)
DBK08 2.0 gph (8.0 lph)
DBK16 4.0 gph (16.0 lph)
• Economic emitter for short runs and non-sloped applications
• Fast, single-barb installation directly onto the hose
• Exit barb may be used with 1/4" (4mm) Leader Tube
(P/N EHD0433) for precision water placement
• Large open flow path for resistance to plugging
• Take apart feature, allows fast simple field inspection
