Compact Home Reverse Osmosis in BOX All-in-One

The closed type 5 stage Hydra 75 Compact LCD unit provide plenty clean and healthy potable water with the safe method of Reverse Osmosis (RO). Main featurer is the innovative design BOX with microcomputer controller and LCD screen for status indication. The booster pump and storage tank inside gives to the unit the ability for installation in low pressure areas.

Compact construction with tank inside for quick and easy installation in any open place. Produces 24 hours every day up to 75 G or 284 liters of clean, fresh and healthy water for drinking, cooking, washing fresh vegetables and fruits etc.


The Best choice for

  • Houses, offices, small cafe-bars.
  • Tap water with high level of conductivity.
  • Well and ground water.
  • Areas with low pressure < 2,8 bar (booster pump included with the system).
  • Water with high concentration of heavy metals.
  • Well water in agricultures areas that might contaminant with .
  • Tap water that might have over dose chlorination.

Technologies included in Hydra 75 Compact LCD
Technology for automatic flushing (clean the membrane)*
Technology for changing the filters
Technology for protection from leaking
LED microcomputer controller with system status indication


Key Point*
The purpose of the flush system is to help prevent scaling or fouling of the RO membrane by providing a rapid rinse which washes away impurities and keeps the membrane clean. Necessary process for high performance and membrane lifetime.


Replacement Filters

Cartridge longevity and performance depend on water usage and level of contamination. We recommend you :
  • Stage 1: Changed Every 6 months  5 Micron Sediment filter (FIS2021)
  • Stage 2: Changed Every 6 months  5 Micron Carbon Block filters (FIC2022)
  • Stage 3: Changed Every 6 months  1 Micron Sediment filter (FIS2023)
  • Stage 4: Changed Every 2-5 years 75 GPD Membrane (ROM0075)
  • Stage 5: Changed Every 12 months 10 Inline Final Filter (FIC2025).
Changing the filters is as simple as push a button.

In the box

  • Fully pre-assembled purification unit with RO membrane 75 GPD and 4 filters.
  • LCD microcomputer controller.
  • 4 lt Water Storage Tank inside.
  • High quality and attractive design faucet.
  • Full fitting kit (10 mt tube, Drain Saddle Valve, Feed water connector).
  • Installation Instruction.



The system hides usually under your kitchen sink and produce 24 hours a day clear and healthy drinking water from a dedicated second faucet.

    Filtration Stages

    Stage 1
    5 Micron Sediment Filter (0,005mm), made from 100% pure polypropylene. Effective in removing dirt, rust and sand particles.
    Stage 2
    Carbon Block Filter (CTO Carbon block) 5μ micron, Removes 99% of the chlorine and organic chemicals. It provides enhanced reduction of taste, odour, and colour. It provides effective filtration to protect your RO membrane.

    Stage 3
    1 Micron Sediment Filter (0,001mm), made from 100% pure polypropylene. Effective in removing dirt, rust and sand particles that remains from the 1st stage.
    Stage 4
    Reverse Osmosis Membrane TFC (Thin Film Composite) It removes 95%-99,9% the following hard water contaminants that may be present in your water: lead, copper, barium, chromium, mercury, sodium, cadmium, fluoride, nitrite, and selenium, Viruses, Legionella, Cysts κ.α.
    Stage 5
    Post Carbon filter. This carbon post filter removes objectionable tastes and odours to enhance the quality of your drinking water. We only use NSF approved post carbon to guarantee the taste of water.
    Stage 6
    Inline Mineralisation Filter re-adds inorganic substances like Calcium Ca, Magnesium (Mg), potassium (K). This filter gives to our final water natural metallic characteristics.
    Stage 7
    Inline Alcaline Filter for increasing final water pH.
    Stage 8
    Ultraviolet Water Steriliser UV is a reliable, efficient & environmentally friendly solution for water disinfection. Efficient UV radiator with a 254nm wave length. 99.99% DESTRUCTION OF BACTERIA AND VIRUSES.
