PURIFICATION PROCESS IN YOUR 
AQUAGUARD

®

 ASTOR RO+UV+MTDS

UV disinfects the water by eliminating waterborne 
disease-causing bacteria, viruses & protozoa, 
thereby making it safe to drink.

i-Filter™

Multi-layered 
Polypropylene roving 
wound cartridge

Chemi-Block 
(with built-in 
Particle Trap 
Filter™)

Dust Free 
Bacteriostatic  
Activated Carbon 
Block 

Removes fine suspended particles such as dust, dirt, 
mud and sand from water.

Reduces excess chlorine, bad odour, colour and 
organic impurities. It also removes very fine turbidity 
causing particles. 

Membrane Life 
Enhancer***

Special Anti-scalant 
Media

Prevents scaling of dissolved salts on the surface of 
the membrane thereby enhancing the membrane life 
and performance.

Thin Film Composite 
(TFC) Reverse 
Osmosis Membrane

UV e-boiling

Germicidal UV Lamp

Copper has antimicrobial, antioxidant, and anti-inflammatory 
properties that help to support healthy metabolism. It also helps to 
provide the body with energy and is much needed for growth and 
development. The activated carbon removes organic components 
and polishes the water, giving it a sparkling look, making it pure and 
great to taste.

Active 
Copper™

Bacteriostatic Taste 
Enhancer with Active 
Copper™ Technology

Reduces TDS, hardness, pesticides and heavy 
metals like arsenic, lead and mercury. Eliminates 
micro-organisms like bacteria, viruses, protozoa 
and cysts.

TDS Regulator Mechanical System

Adjusts the TDS of purified water to provide healthy 
water always.

TECHNICAL SPECIFICATIONS*

A QUICK CHECKLIST

CARTRIDGE LIFE

Note: Please refer Standard Test Conditions

#

 for filter life. 

**As per manufacturer's spec.

Water tastes 
bad 

1. Is the tank clean? 
2. Have you kept the purified 
    water in the tank for too 
    long? 
3. Is it time to change the 
    filter? 

Less water has
been purified 

1. Is the tap water valve 
    closed? 
2. Is the tap water pressure 
    too low? 
3. Filters may be clogged or 
    damaged?

Water doesn't
flow into the
storage tank 

1. Is there water available in 
    the overhead tank? 
2. Is the main water supply 
    tap closed? 
3. Not sure what is wrong?

Water is 
leaking

1. Is water coming out of 
    the top of the purifier?

1. Clean the storage tank. 
2. Dispose of water and clean the tank.
3. Call an authorised Eureka Forbes 
    service technician.

1. Open the tap water valve. 
2. If so, the amount of purified water will 
    be reduced. 
3. Call an authorised Eureka Forbes 
    service technician.

1. Ensure the overhead tank is filled with 
    water. 
2. Ensure the tap is open.
3. Call an authorised Eureka Forbes 
    service technician.

1. Close the tap water valve, unplug the 
power cord and call an authorised Eureka 
Forbes service technician.

PRODUCT SPECIFICATION

For Aquaguard

®

 Astor RO+UV+MTDS / RO / UV+UF (Refer model specific components)

***Not a part of the product, Membrane life enhancer is recommended if the input water TDS is more than 1000 ppm 
(mg/L) or input water hardness is more than 300 ppm (mg/L). Available at extra cost

*Technical Specifications are subject to change without prior notice.
Note: SMPS is designed to operate from 150VAC to 280VAC).
Note: The performance data presented in the table is applicable under standard laboratory conditions

#

Actual performance may vary depending on the input water quality, water pressure, turbidity and 
condition of filters. Input water quality/pressure/TDS are important determinants of recovery rate and 
rejection.
**If the input water pressure is more than 3.0 kg/cm

2

, installation of a PRV (Pressure Reducing Valve) 

is mandatory. If the input water pressure is less than 0.3 kg/cm

2

, installation of a booster pump is 

recommended.     
  If the input water TDS is more than 1000 ppm (mg/L) or input water hardness is more than 300 ppm 
(mg/L), use of a Membrane life enhancer is recommended.
These accessories are available at an extra cost.
    

Warranty void if not installed as per recommendations.
