RA300-19 Rainbow 300-19 Off-Line Feeder for Chlorine or Bromine – Chemical Feeders & Solenoids

Introduction

Versatile chemical feeding requires equipment that accommodates multiple sanitizer types, and the Rainbow 300-19 provides reliable off-line feeding for both chlorine and bromine applications. As a retailer of hot tub & pool spare parts, I stock this dual-purpose feeder that delivers consistent chemical dissolution and distribution for flexible pool and spa sanitization systems.

Dual Chemical Compatibility

The Rainbow 300-19 is specifically designed to handle both chlorine and bromine chemicals, providing installation flexibility for different sanitization preferences and requirements. This dual compatibility eliminates the need for separate feeders when switching between chemical types or accommodating different seasonal requirements.

The versatile design ensures optimal dissolution characteristics for both chemical types while maintaining consistent feeding performance regardless of the sanitizer choice.

Off-Line Feeding Configuration

The 300-19 utilizes off-line feeding design that draws water from the main circulation system, passes it through the chemical chamber for controlled dissolution, and returns treated water to the pool circulation. This configuration ensures proper chemical mixing while protecting pool equipment from concentrated chemical exposure.

The off-line design provides consistent chemical delivery while preventing equipment damage that could occur from direct exposure to undissolved chemicals in the main circulation flow.

Professional Rainbow Construction

Rainbow’s proven manufacturing ensures the 300-19 delivers reliable performance with chemical-resistant materials designed for continuous feeding applications. The durable construction withstands exposure to both chlorine and bromine while maintaining structural integrity throughout extended service periods.

Quality construction ensures consistent chemical feeding while the proven design provides the reliability standards expected in professional pool and spa applications.

Controlled Chemical Dissolution

The feeder chamber design ensures controlled water flow that promotes complete chemical dissolution while preventing tablet bridging or incomplete dissolution that could cause inconsistent chemical delivery. Proper dissolution ensures steady sanitizer levels for optimal water treatment.

The controlled flow characteristics accommodate both chlorine and bromine tablets, ensuring optimal dissolution rates for each chemical type while maintaining consistent feeding performance.

Flexible Application Range

The 300-19 accommodates various installation sizes and chemical requirements, making it suitable for residential pools, spas, and light commercial applications requiring reliable dual-chemical feeding capability.
