Rain Bird CP3504PC Professional Rotor 12-Pack — Rain Curtain Nozzles, Full-Circle, 15'–35' Coverage, Adjustable Arc

The Rain Bird CP350012PK is a 12-pack of professional-grade CP3504PC gear-drive rotors with Rain Curtain nozzles, engineered to deliver uniform 15'–35' coverage and adjustable 40°–360° arcs for efficient residential and light-commercial irrigation.

This bulk set includes twelve CP3504PC closed-case rotors preinstalled with a 3.0 GPM nozzle plus twelve matching Rain Curtain nozzle trees (six nozzle sizes per tree), providing versatile flow and radius control for lawns, gardens, and landscape beds. The rotor combines water-lubricated, gear-driven reliability with a true 4" pop-up height, a factory 180° preset arc, and an easy radius adjustment screw that reduces throw up to 35% without swapping nozzles. Built for uniformity and durability, the Rain Curtain nozzles create large droplets that fall precisely where needed to resist wind drift and reduce runoff.

How do these rotors ensure even watering across a lawn?

The CP3504PC rotors use Rain Bird’s Rain Curtain nozzle technology to produce a rotating curtain of large droplets that maintain trajectory and placement. This minimizes gaps and dry spots while the micro-ramps add close-in coverage so turf near the head receives adequate moisture.

• Matched nozzle set: .75, 1.0, 1.5, 2.0, 3.0, 4.0 GPM for precise flow tuning.
• Rotating curtain design reduces wind-driven mist and improves uniformity.
• Close-in spray eliminates dry rings and reduces seed washout.

What adjustments can I make in the field without special tools?

Simple, screwdriver-accessible controls let you change arc from 40° to 360°, perform a quick-check arc while the head is running, and fine-tune radius up to 35% smaller using the radius adjustment screw. No special tools or nozzle swaps are required for most on-site tweaks.

• Flat-head screwdriver adjustable arc and radius settings.
• Quick check/fast-forward feature verifies arc during operation.
• Self-aligning nozzles and removable filter screens simplify maintenance.

How durable and maintenance-friendly are these rotors?

The CP3504PC’s closed-case, water-lubricated gear drive and dual-action wiper seal protect internal parts from grit and debris, extending lifespan in tougher soil conditions. Removable filter screen and nozzle removal features make servicing straightforward and reduce downtime.

• Closed-case design resists sand and creeping grasses.
• O-rings, seals, and rubber-encased cover add resilience in gritty water.
• Self-adjusting stator eliminates replacement when changing nozzles.

What installation and performance specifications should I plan for?

These rotors accept a 1/2" NPT female bottom inlet and operate efficiently at typical residential pressures (25–55 psi), providing spray distances between 15' and 35'. Each rotor ships with a preinstalled 3.0 GPM nozzle and the included nozzle tree allows you to match flow to site conditions.

• Flow rate range: 0.54–4.6 GPM depending on nozzle selection.
• Designed throw: 15'–35' at 25–55 psi; true 4" pop-up height.
• Factory preset arc: 180° for simpler layout; adjustable to full circle.

Who is this for? Landscapers, irrigation contractors, and homeowners who need a cost-effective bulk solution for consistent, durable sprinkler performance will benefit from this 12-pack. It’s ideal for new system installs, multi-zone retrofits, or replacing multiple rotor heads to improve uniformity, reduce water waste, and simplify maintenance across medium to large residential lawns or light-commercial landscapes.
