Complete set of RO3 aquarium filter cartridges membrane

Complete service kit for the RO3 system in an aquarium

The kit has been prepared for typical water filtration systems based on reverse osmosis. It includes all the basic elements needed to replace the most important consumable cartridges and the membrane in a water filter operating in an RO3 setup.

By combining mechanical filtration, carbon cartridge filtration, and separation on the membrane, the kit helps remove a broad spectrum of contaminants while protecting the key component of the reverse osmosis system.

Characteristics of the cartridges and kit components

WPL2 inline sediment cartridge

WPL2 is an inline cartridge made of polypropylene foam. Its purpose is preliminary mechanical water filtration and retaining typical solid contaminants that could impair the operation of subsequent filtration stages.

• Type: inline, polypropylene foam
• Function: filtration of sand, silt, rust, and other solid contaminants
• Filtration accuracy: < 20 mic
• Length: 10"
• Diameter: 2"
• Service life: 3-6 months
• Operating temperature range: 2-42 °C

WWL2 inline carbon cartridge

WWL2 is an inline carbon cartridge responsible for reducing substances that may affect water quality and membrane life. It is an important stage of water preparation before it reaches the osmosis membrane.

• Type: inline, carbon
• Function: removal of chlorine, chlorine compounds, and organic contaminants
• Filtration accuracy: < 5 mic
• Length: 10"
• Diameter: 2"
• Service life: 3-6 months
• Operating temperature range: 2-42 °C

VONTRON 100 GPD membrane

The VONTRON 100 GPD osmosis membrane is the main purification element in the RO3 system. It is responsible for retaining a very broad range of contaminants, making it a key part of every reverse osmosis filter used to prepare aquarium water.

• Function: retains 96%-99% of contaminants, including organic and inorganic contaminants, heavy metals, and some bacteria and viruses
• Capacity: 100 GPD (380 L/24h)
• Dimensions: 11,9*1,8"
• Operating temperature: 2-45 °C
• Operating pressure: 2,8-6 bar

FLOW 550 flow restrictor

FLOW 550 is responsible for properly reducing the water flow directed to the drain. This is an important component for correct membrane operation and maintaining proper conditions for the entire water filtration system.

• Function: reducing water flow to drain, membrane protection
• Quick connector: 2x 1/4" JG type
• Operating temperature: 2-42 °C
• Safety clips included

How this set works in a reverse osmosis system

The kit forms a coherent service setup for the RO3 aquarium filter. In the first stage, the sediment cartridge captures sand, silt, rust, and other solid contaminants. Next, the carbon cartridge reduces chlorine, chlorine compounds, and organic contaminants. Finally, the osmosis membrane performs precise filtration, retaining 96%-99% of contaminants, including organic and inorganic compounds, heavy metals, and some bacteria and viruses.

This combination of components supports effective water treatment and helps maintain the proper operating conditions of the membrane, which is the most important component of any reverse osmosis system.

Key benefits

• Complete kit for servicing typical aquarium water filtration systems using reverse osmosis
• High efficiency in removing a wide range of contaminants
• Combination of mechanical, carbon, and membrane filtration in one set
• Membrane protection thanks to the use of appropriate pre-filters and a flow restrictor
• Universal use in most RO systems, including aquarium systems
• Convenient replacement of the main consumable components during one service

Compatibility and application

The kit fits typical RO3 systems. It works well as a replacement set for osmosis filters used in aquaristics, where water purity and stable membrane operation are especially important.

This solution is intended for users who want to keep the water filtration system fully functional without sourcing components separately.
