The Netafim SuperNet PC Sprinkler Assembly is a professional-grade, pressure-compensating micro-sprinkler designed for orchard irrigation, vineyard blocks, nurseries, and new tree plantings. Each assembly arrives completely pre-built and ready to connect — including the sprinkler body with stock spinner, a 30" length of 1/4" supply tubing, and a 1/4" transfer barb for attaching directly to your mainline tubing. No assembly required; just punch in and start irrigating.
What makes the SuperNet stand out from ordinary micro-sprinklers is its pressure-compensating (PC) diaphragm, which maintains a consistent, uniform flow rate across a wide pressure range of 25–50 PSI. That means every tree on a long row — or on uneven, sloped terrain — receives the same amount of water regardless of pressure variation from one end of the line to the other. The result is dramatically better distribution uniformity, healthier trees, and less water waste. The SuperNet also features the largest water passages on the market, making it highly clog-resistant, and a drop-down swivel plate that acts as a bug-proof barrier to prevent insects from entering the nozzle.
The assembly is available in three flow rate options to match your tree spacing and water requirements: Purple base (5.3 GPH) for low-flow applications, Blue base (10.9 GPH) for medium coverage, and Black base (18.9 GPH) for high-flow, widely-spaced trees. All three models share the same PC technology and swivel spinner system.
One of the SuperNet's most practical advantages is its grow-with-the-tree spinner system. When a tree is young and its root ball is small, replace the stock spinner with the optional Blue Spinner with Breakaway Deflector (MSNSBLD) to concentrate irrigation right at the base of the young plant. As the tree matures and its root zone expands, simply snap off the deflector to widen the wetted diameter to full coverage. For fully mature trees, swap back to the stock spinner for maximum radius and flow. This three-stage system eliminates the need to replace hardware as your orchard matures.
Use the Blue Support Stake (MSNSTK) (sold separately) to elevate and stabilize the sprinkler above the ground. For a complete orchard irrigation system, pair the SuperNet with a filter (80 mesh minimum recommended), a pressure regulator to keep your system within the 25–50 PSI range, and a timer or controller for automated scheduling.
The table below shows the wetted radius (measured at 8" above ground) for each SuperNet base model combined with each spinner configuration. All flow rates are average mean values measured at 25–50 PSI.
| Base Model (SKU) | Flow Rate | Spinner Config | Wetted Radius |
|---|---|---|---|
| Purple Base (MSNP / MSNPT) | 5.3 GPH | Purple stock spinner | 8 feet |
| Blue spinner, with deflector | 2 feet | ||
| Blue spinner, deflector removed | 4 feet | ||
| Blue Base (MSNBLU / MSNBLUT) | 10.9 GPH | Purple stock spinner | 8.5 feet |
| Blue spinner, with deflector | 3 feet | ||
| Blue spinner, deflector removed | 5.5 feet | ||
| Black Base (MSNBLA / MSNBLAT) | 18.9 GPH | Black stock spinner | 10 feet |
| Blue spinner, with deflector | 3 feet | ||
| Blue spinner, deflector removed | 8 feet |
Note: "MSNPT," "MSNBLUT," and "MSNBLAT" are the assembly SKUs (with tubing pre-attached). "MSNP," "MSNBLU," and "MSNBLA" are the body-only SKUs. Flow rates shown are average mean values at 25–50 PSI.

What does "PC" mean, and why does it matter for orchards?
PC stands for Pressure Compensating. The SuperNet contains a floating rubber diaphragm that adjusts the internal flow path to maintain a consistent output regardless of fluctuations in inlet pressure. In an orchard or vineyard where rows may be long or the terrain is uneven, pressure at the end of a run can be significantly lower than at the beginning. With a standard (non-PC) sprinkler, that means trees at the end of the row get less water. With the SuperNet PC, every tree gets the same flow — which translates to uniform growth, more consistent crop yield, and less water waste.
Which flow rate (Purple, Blue, or Black) should I choose?
Base selection depends primarily on your tree spacing and the total number of sprinklers on each irrigation zone. The Purple base (5.3 GPH) is ideal for closer tree spacings or lower-flow applications. The Blue base (10.9 GPH) suits medium spacings and is the most common choice for established orchards. The Black base (18.9 GPH) is designed for wider-spaced, mature trees with larger root zones that require greater water volume per cycle. Consult your zone flow capacity and the spacing table in the Netafim spec sheet (available in the Downloads section) to confirm the right model for your layout.
How do I use the blue spinner with deflector for young trees?
When a tree is newly planted, its root zone is small and concentrated near the trunk. Remove the stock spinner from your SuperNet base and replace it with the Blue Spinner with Breakaway Deflector (MSNSBLD). The deflector concentrates the spray into a tight radius directly around the young tree's root ball — typically 2 to 3 feet depending on your base model. As the tree grows and its root zone expands, simply snap off the deflector to increase the wetted diameter to 4–8 feet. When fully mature, swap back to the stock spinner for maximum coverage.
What filtration is required?
Netafim recommends a minimum of 80 mesh filtration for all SuperNet micro-sprinkler installations. While the SuperNet features the largest water passages on the market for clog resistance, a proper inline filter protects the diaphragm and bearing from debris in your water supply. DripWorks carries a full range of compatible screen and disc filters. For surface water or well water with high organic content, a disc or media filter is recommended.
Can I use the SuperNet on a drip system with other emitters on the same zone?
Yes, but you should account for the flow difference. SuperNet micro-sprinklers operate at significantly higher flow rates than standard drip emitters (which typically run at 0.5–2 GPH). Mixing sprinklers and drippers on the same zone can make uniform scheduling difficult. For best results, run SuperNet micro-sprinklers on dedicated zones separate from inline drip tubing or emitters. Use a multi-zone timer to schedule them independently.
Can I hang the SuperNet from a trellis wire instead of using a ground stake?
Yes. The SuperNet body includes an integral hook that allows it to be suspended directly from trellis wire — a common installation method in vineyards. For ground-level mounting, use the Blue Support Stake (MSNSTK) to elevate the sprinkler above the soil surface.
What chemicals should I avoid using with the SuperNet?
Netafim advises against injecting harsh chemicals such as acids through the SuperNet. Fertilizers and amendments like gypsum and lime can clog the sprinkler and cause premature wear. If you plan to use a fertilizer injector, use only water-soluble fertilizers compatible with micro-irrigation systems and always flush the system after injection.
Is the diaphragm replaceable?
Yes. The rubber pressure-compensating diaphragm inside the SuperNet base can be replaced without discarding the entire sprinkler. Order the Replacement Diaphragm (MSNDIA) from DripWorks, available as part of the SuperNet Accessories listing.
