NGE®AL
Anti-Drain Pressure Compensating Emitter
Application:
The NGE AL pressure compensating emitter is ideal for
greenhouse and nursery applications, or any situation that
requires precise irrigation of containers or individual
plants. Water is applied uniformly from each emitter
outlet, and the unique anti-drain feature eliminates
drainage caused by differences in elevation.
Features and Benefits:
• Acid resistant high-grade material
construction provides the emitter with
superior weathering characteristics and
protection against chemical degradation.
• The unique emitter design and pressure
compensating diaphragm allows:
- The emitter to remain closed until an opening
pressure of 13 psi (0.9 Bars) is achieved. As a result,
start-up time is kept to a minimum, and uniformity is
maximized.
- Self-flushing during operation to facilitate cleaning.
- The emitter to shut-off at 3.0 to 5.0 psi (0.24 to 0.34
Bar) depending on the emitter flow rate. This
prevents complete drainage of system pipes and
facilitates efficient system pulsing. Quicker system
start-up also results in a reduction of chemical and
fertilizer waste.
- The emitter to close upon system shut down, thus
inhibiting back siphoning and reducing the risk of
emitter clogging.
• The semi-circle inlet filters and large
turbulent flow path design provide clogging
resistance by preventing large debris from
entering the emitter, and by allowing smaller
particles to exit the flowpath during the selfflushing cycle.
• The exceptional emitter design allows
uniform flow rates from 13 to 60 psi (.9 to
4.1 Bar). This wide range allows use in
demanding applications, even in nurseries
and greenhouses where exceptional
precision is required. The pressure
compensating feature, along with a
manufacturing Cv of 3% or less makes the
NGE one of the highest performing emitters
available.
• Also available in a male adapter (-MA) outlet
outlet configuration with an internal bug
shield, allowing use with 1/4" (4mm) leader
tubes or Black Spider multi-outlet devices.
• Available in four flow rates:
DPC02-MA-AL-Blue 0.5 gph (2.0 lph)
DPC03-MA-AL-Green 0.8 gph (3.0 lph)
DPC04-MA-AL-Gray 1.0 gph (4.0 lph)
DPC08-MA-AL-Red 2.1 gph (8.0 lph)
