800GPD Direct Flow RO System
The LSRO-800D is an under-sink reverse osmosis system that purifies tap water directly—without the use of a storage tank. By filtering water on demand, it reduces the risk of bacteria buildup and saves space. A smart LED faucet displays real-time water quality and reminds users when to replace filters—helping ensure consistently fresh, clean, great-tasting water.
Built for modern living, Lan Shan’s LSRO-800D Tankless RO System offers more than just clean water – it brings together advanced filtration, intuitive design, and smart functionality. Below are key features that make it an efficient and user-friendly choice for everyday water purification.
Key Features
Solve the TDS creep
Patented back flush technology automatically rinses the RO membrane, flushing out residual buildup. This ensures the first cup after idle time has lower TDS and maintains the same clean, great-tasting quality as every cup that follows.Smart Display & LED Faucet
A user-friendly touch panel shows real-time TDS levels and the inlet water temperature – an indicator of the total dissolved solids in your water, which affect its taste and purity – along with system status and alerts. The LED faucet displays water quality and reminds users when to replace filters.Quick, Hassle-Free Maintenance
All filters are tool-free quick change filter design and easy to replace using a magnetic side cover. Electric leak detection with auto shutdown inlet water source function adds extra peace of mind.Tankless, Space-Saving Design
Filters water on demand without a storage tank – freeing up valuable under-sink space.Efficient & Eco-Friendly
With a 1:0.8 pure-to-waste water ratio, it helps reduce water waste by up to 74% compared to traditional RO systems.Appearance design
LSRO-800D gets many appearance design patents in many countries, such as the USA, Europe, Taiwan and China.
Applications
Perfect for home kitchens, small cafes, baby formula preparation, tea and coffee brewing, or any setting where space-saving, high-quality water filtration is needed.
Designed for clean water and peace of mind, the LSRO-800D Tankless RO System makes daily hydration easier and smarter. Contact Lan Shan to learn more or request a quote tailored to your needs.
Q1: What is a Direct Flow RO system?
A Direct Flow RO system, also known as a tankless RO system, purifies water on demand without using a storage tank. Unlike traditional systems that store filtered water in a tank, Direct Flow systems deliver freshly filtered water straight to the faucet in real time.
Q2: What is the minimum inlet water pressure required for the LSRO-800D?
The LSRO-800D requires a minimum inlet water pressure of 20 psi to operate. Inlet water pressure refers to the pressure of the tap water entering the system. Sufficient pressure is needed to push water through the RO membrane; if pressure is too low, a booster pump may be required to maintain proper flow and efficiency.
Q3: What is the pure-to-waste water ratio for the LSRO-800D?
The LSRO-800D has a water recovery ratio of 1:0.8—meaning for every 1 glass of purified water, approximately 0.8 glass of wastewater are discharged. This is more efficient than many traditional RO systems.
Q4: Why is it important to solve TDS creep?
The TDS creep occurs when the system does not activate for a while. The pure water and the wastewater will be mixed together in the RO membrane housing. After a while when people get the water from the system, the initial TDS is high which we called TDS creep. Solving the TDS creep is to make sure users can drink the pure water every time when they take the first glass of water.
Q5: Why is the function of detecting water inlet temperature important?
The pure water flow rate depends on the water temperature. With the characteristic of the RO membrane, the lower temperature produces less pure water vice versa.The function of detecting water temperature can easily to determine the lower flow rate whether caused by the temperature.
