Complete Guide to N Series Pop-Up Scatter Nozzles: N4/N6/N8/N10/N12/N15/N17 Difference & Selection Tips
Pop-up scatter nozzles are the core interchangeable component of underground retractable sprinkler systems, widely adopted in residential yards, community lawns, municipal greenbelts, parks and roadside landscaping. Our N series scatter nozzles cover 7 complete models: N4, N6, N8, N10, N12, N15 and N17, with distinct spray radius, flow rate and atomization performance to match all irrigation scenarios from narrow flower beds to large open plazas.
This guide fully explains the naming rules, core parameters, key differences, layout standards and universal shared features of all N series models, helping landscape contractors, irrigation engineers and property managers pick the perfect nozzle for every project.
1. N Series Nozzle Naming Standard
The naming rule of N series pop-up scatter nozzles is simple and intuitive for fast selection:
- Letter N: Short for Scatter Nozzle, representing fixed spray scattering type;
- Suffix Number: Standard effective spray radius in meters under 0.2MPa nominal water pressure.
Core rule: The larger the number, the bigger the nozzle outlet hole, longer spraying distance, higher water flow per hour, and wider single-head coverage area.
All N series nozzles share universal compatibility: fit most mainstream 4-inch and 6-inch pop-up sprinkler bodies (including Rain Bird 1804, NV400 and other domestic equivalent shells), with adjustable spraying arc from 0° to full 360°.
Core Technical Parameter Table (0.2MPa Standard Working Pressure)
| Model | Standard Spray Radius | Flow Rate (m³/h) | Nozzle Hole Size | Irrigation Uniformity & Atomization | Suitable Application Scenarios |
|---|---|---|---|---|---|
| N4 | 1.2 m | 0.11 | Minimum | Fine mist, high uniformity, low impact | Narrow green strips, tree pits, sidewalk gaps, flower bed edges, building corners |
| N6 | 1.8 m | 0.18 | Small | Soft fine water droplets | Small flower borders, narrow isolation belts along walls |
| N8 | 2.4 m | 0.26 | Medium-Small | Balanced atomization & coverage | Small private lawns, shrub clusters, courtyard corners |
| N10 | 3.0 m | 0.35 | Medium | Even water distribution, universal performance | Standard residential yards, regular flower gardens, small green plots |
| N12 | 3.6 m | 0.48 | Medium-Large | Wide coverage, mild droplet size | Community public lawns, medium roadside greenbelts, large color-block planting zones |
| N15 | 4.5 m | 0.72 | Large | Long throw, low irrigation intensity | Park lawns, sports field perimeters, large flat green spaces |
| N17 | 5.1 m | 0.95 | Maximum | Widest coverage, thick anti-wind droplets | Large open lawns, urban plaza landscaping, extra-wide highway green belts |
3. Five Core Differences Between All N Series Models
3.1 Spray Range (Most Obvious Distinction)
The digital suffix directly decides the maximum spray distance: N4 delivers the shortest 1.2m radius, while N17 reaches up to 5.1m.
- Small-size N4/N6: Designed for cramped edge zones to avoid water splashing on walls, pavements or road surfaces;
- Large-size N15/N17: Optimized for barrier-free open green areas to cut down total sprinkler quantity and reduce project cost.
3.2 Water Flow & Pipeline Load Matching
Larger model numbers bring higher hourly water consumption under identical water pressure, which directly affects zoning pipeline design:
- N4 & N6: Ultra-low flow output. Each irrigation zone can install more sprinklers without pressure drop, ideal for scattered small green patches;
- N15 & N17: Heavy water demand. Engineers must reduce the number of nozzles per zone, otherwise insufficient water pressure will shrink spray radius and cause uneven irrigation.
3.3 Atomization Effect & Plant Adaptability
Different droplet sizes match diverse plant root characteristics:
- N4–N10: Ultra-fine mist droplets, gentle watering impact. Perfect for shallow-root flowers, seedlings and delicate shrubs; no soil erosion or seed washing away risk;
- N12–N17: Thicker, heavier water streams with weaker atomization. Resist wind drift under breezy conditions, specially suitable for deep-root turf grass.
3.4 Installation Spacing for Engineering Layout
Standard layout distance based on spray radius (30% overlapping coverage recommended for full uniform watering):
- N4 / N6: Dense layout, 1.2–1.8m between each sprinkler;
- N8 / N10: Standard residential spacing, 2.4–3m apart;
- N12 / N15 / N17: Wide layout for large projects, 3.6–5m separation to save material and construction labor.
3.5 Scenario Matching Guide for Quick Selection
- N4 & N6: Narrow roadside strips, tree pits, building wall corners, flower bed borders, sidewalk gaps;
- N8 & N10: Private home gardens, small residential lawns, shrub planting groups — the two best-selling models for household landscaping;
- N12 & N15: Residential community public lawns, city parks, medium-width highway greenbelts;
- N17: Extra-large open turf, sports complex outer green zones, city plaza landscape with no obstacles.
4. Universal Shared Features of All N Series Scatter Nozzles
All seven N series models retain the same core functional design, bringing unified installation, maintenance and compatibility advantages for irrigation projects:
- Full arc adjustment: Freely switch spraying angle from 0° to 360°, supporting quarter-circle, half-circle and full-circle watering to fit irregular plot shapes;
- Wide sprinkler body compatibility: Works with nearly all global mainstream 4-inch and 6-inch pop-up sprinkler housings, convenient for system renovation and replacement;
- Built-in detachable filter screen: Effectively blocks sand, sediment and debris in water pipelines to prevent nozzle clogging; the filter can be removed separately for quick cleaning without tools;
- Adjustable range control: A limit screw on the top of each nozzle allows manual reduction of maximum spray radius, flexible to adapt irregular edge zones without replacing nozzles.
5. Quick Selection Mnemonic for Engineers & Buyers
Narrow flower beds & tight corners → N4 / N6
Small private yards & home lawns → N8 / N10
Community parks & medium green belts → N12 / N15
Large open plaza & wide turf fields → N17
Conclusion
The complete N series pop-up scatter nozzles (N4 to N17) form a full-range irrigation solution covering all green space sizes, from tiny planting edges to large municipal landscapes. Standardized interchangeable design reduces inventory pressure for contractors, while graded flow and spray radius guarantee water-saving, uniform irrigation for every project.
