Power Grow RO Unit 500 by GrowMax is a high quality reverse osmosis system capable of producing up to 20 litres per hour of pure water. GrowMax Water reverse osmosis systems are the best available for the growing and gardening industry today. These units produce pure water-this unit produces 500 liters per day and includes features like pressure gauges, flow restrictors, and automatic shut-off valves to ensure your system will maintain optimum performance and reliable service for many years.

The Power Grow 500 reverse osmosis unit is designed to lower the PPM / EC, remove chlorine and sediment from your water supply. Water with a lower EC 0.0 - 0.2 allows much more of the correct nutrients to be fed and absorbed by your plants. Chlorine and sediment free water is essential to growing healthy plants and maintaining beneficial micro organisms, bacteria and fungi in your root zone and growing media. These microbes cannot survive in the presence of chlorine.

Water usage with the Power Grow 500 reverse osmosis system has been optimised to achieve 60% waste water / 40% pure water. If needed 10-20% tap water can be added to aid pH stability.

IMPORTANT: A minimum of 2.75bar 40 psi is required to operate the system properly. To increase water pressure a booster pump kit is available separately. Do not install the system where the incoming water pressure higher than 5.5bar / 80psi, pressure can be reduced by installing a pressure regulator. Only use with cold water supply, hot water will damage the filters and membrane. Protect unit against frost.
