Pentair Model 320 In-Line Rainbow Feeder

RRP: £216.00



Pentair Model 320 in-line rainbow feeder, not only saves time but also reduces manual handling of chemicals. They use large or small trichlor or bromine slow-dissolving tablets to make sanitizing your new or existing pool or spa easy and automatic. Both are installed easily on the pressure side of the pump, downstream of the filter and heater.

The in-line Model 320 feeder features an external fine-control valve that lets you adjust the feed rate to meet specific pool or spa requirements. Ideal for retrofitting existing pools for automatic sanitisation. The Model 320 feeder is designed for permanent installation in the return line of new or existing systems and dispenses sanitizer directly into your pool or spa, downstream of all equipment. Completely enclosed systems—no escaping fumes.

The Pentair Model 320 in-line rainbow feeder do not require special venting and hold 11x 200g tablets or 98 x 20g tablets, making refilling needed less frequently.
