K-Rain 13003 MiniPro 4-Inch Gear-Drive Rotor

K-Rain 13003 MiniPro 4-Inch Gear-Drive Rotor

Brand: K-Rain | SKU: 13003

Product Overview

The K-Rain 13003 MiniPro is a compact 4-inch gear-driven rotor for small to medium lawns and landscape zones. It combines adjustable part-circle and full-circle operation in one head and uses five interchangeable nozzles to help match coverage to the site’s pressure and flow.

This is the standard MiniPro model rather than the separate factory check-valve or reclaimed-water configurations. Before ordering, confirm the 1/2-inch inlet, required radius, available dynamic pressure, total zone flow, head spacing, and exact model suffix needed for the project.

Frequently Asked Questions

Is K-Rain 13003 a K1 Smart Set rotor?
No. K-Rain identifies model 13003 as the 4-inch MiniPro rotor.

What is the adjustable arc range?
The MiniPro adjusts from 40° through full-circle operation.

Does model 13003 include a check valve?
Do not assume it does. Choose the specific CV model when a factory-installed check valve is required.

Can it replace any spray body?
No. The connection may fit some systems, but pressure, flow, spacing, and precipitation must also be compatible.
