Pentair PRF RO Merlin Tankless Reverse Osmosis
High-Flow Tankless Reverse Osmosis Water Filter
Enjoy exceptionally pure drinking water with one of the highest-flow domestic reverse osmosis systems available.
The Merlin Tankless Reverse Osmosis System combines advanced reverse osmosis technology with an innovative tankless design, delivering fresh purified water directly from your mains supply whenever you need it. Producing up to 720 gallons (approximately 2,725 litres) per day, the Merlin eliminates the need for a bulky storage tank while providing a significantly higher flow rate than most conventional reverse osmosis systems.
Unlike traditional reverse osmosis systems that slowly fill a storage tank before water can be used, the Merlin continuously produces purified water on demand. This means you benefit from fresh, cool, great-tasting water without waiting for a storage tank to refill or sacrificing valuable cupboard space.
Why Choose the Merlin Tankless Reverse Osmosis System?
- Produces up to 720 gallons per day (GPD) of purified water.
- Delivers approximately 0.5 US gallons (around 1.9 litres) per minute.
- Tankless design for fresh water on demand.
- No bulky storage tank required.
- No booster pump required (subject to suitable incoming water pressure).
- Removes up to 99% of many dissolved contaminants, helping to improve the quality, taste and odour of your drinking water.*
- Compact under-sink installation.
- Only one pre-filter and one post-filter typically require replacement every six months.
- High water production makes it ideal for demanding domestic and specialist applications.
Fresh Water On Demand
The Merlin is designed for households that want a premium reverse osmosis system without the compromises of conventional tank-based units.
Because water is purified as it is required, you don't have to wait for a storage tank to refill after heavy use.
Exceptional Purity
Reverse osmosis is recognised as one of the most effective methods of producing high-quality drinking water.
The Merlin's high-performance membrane can reduce a wide range of dissolved solids and contaminants, helping provide exceptionally pure water for drinking and food preparation.
Its impressive flow rate also makes it suitable for applications where larger volumes of purified water are required.
Ideal Applications
The Merlin Tankless Reverse Osmosis System is ideal for:
- Drinking water
- Cooking and food preparation
- Tea and coffee machines
- Ice makers
- Aquariums and marine systems
- Hydroponics
- Laboratories
- Filling dehumidifiers and steam appliances
- Window cleaning systems
- Producing purified water for spot-free car detailing when feeding a deionisation (DI) vessel, helping achieve a mineral-free rinse for a streak-free finish.
Easy Maintenance
The Merlin has been designed for reliable long-term performance with minimal maintenance.
Under normal domestic use:
- One pre-filter typically requires replacement every six months.
- One post-filter typically requires replacement every six months.
- The reverse osmosis membrane has a considerably longer service life, depending on incoming water quality and usage.
