800GPD Pro RO System
800GPD Pro RO System
The 800GPD professional RO system is an economical solution for getting high-quality purified water. It can produce up to 3,000 liters of RO water per day, or about 125 liters per hour.
This system is ideal for businesses that need a large amount of pure water. Click here for more details on this product.
Which consumables?
- 1 x 20-inch PP filter for professional and industrial use: These filters physically allow through only particles smaller than a certain diameter, removing dust and other large impurities.
- 1 x GAC filter for professional and industrial use: pre-filter with granular activated carbon, very effective at trapping impurities.
- 1 x CTO filter for professional and industrial use: activated carbon block filter that traps impurities such as chlorine, organic contaminants, pesticides and other chemicals.
- 1 x 400 GPD membrane for professional RO systems: removes heavy metals, bacteria and viruses. The pores of a reverse osmosis membrane are so small that they let only water molecules (H2O) through.
- 1 x T33 post-membrane filter cartridge: made of coconut shell carbon. It enhances the taste of your water after reverse osmosis and removes residual odors from the pure water leaving the tank.
How often?
Depending on the type of consumable, the replacement frequency will vary, for example:
- All filters: every 6 months to 1 year.
- The membrane: two years on average
- The post-membrane cartridge: optimal service life of 12 to 18 months
If you want to save money, we offer a maintenance kit for the 800GPD RO system with a 2-year service life that is more cost-effective than buying the consumables individually.
