Toro Micro Irrigation NGE® AL Anti Drain Pressure Compensating Turbulent Flow Emitters

The NGE® AL pressure compensating emitter is made 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:

• Acid resistant high grade material construction provides the emitter with weathering resistant characteristics and protection against chemical degradation.
• The unique emitter design and pressure compensating diaphragm allows:
  1. the emitter to remain closed until an opening pressure of 15 psi / 1.03 bar is achieved to maximize uniformity.
  2. self-flushing during operation to facilitate cleaning.
  3. the emitter to shut off at 3.5 psi / 0.24 bar. 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.
  4. the emitter to close upon system shut down, thus inhibiting back siphoning and reducing the risk of emitter clogging.
• The 3mm barbed outlet is suitable for use with micro distribution hoses and the male adapter outlet is suitable for use with spider assemblies.
• 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 flow path during the self-flushing cycle.
• The emitter design allows uniform flow rates in demanding applications even in nurseries and greenhouses where exceptional precision is required. Manufacturing Cv of 3% or less allows for high performance.
• Available in 4 flow rates:
  Flow rate expressed in gph at 30psi (2 bar)
