Designed specifically for whole-home applications, the Lunde Series integrates seamlessly at the main water entry point, making it ideal for villas, apartments, and any residential setting where clean, sediment-free water is essential for protecting plumbing, appliances, and everyday water quality.

Uninterrupted Water Flow for Daily Household Use

The Lunde Series delivers up to 6.0 m³/h — equivalent to approximately 100 litres per minute — ensuring stable pressure even when multiple taps, showers, and appliances run simultaneously. Whether showering, doing laundry, or washing vegetables, the whole household enjoys consistent water pressure without noticeable drops.

Self-Cleaning Intelligence That Reduces Manual Maintenance

The innovative 3-in-1 cleaning system works automatically to keep the filter mesh clean — combining forward flushing, siphon backwashing, and 360° internal scraping to remove both loose and stubborn impurities. Once installed, the system takes care of itself, saving you the time and effort of frequent manual disassembly.

Smart Flushing That Adapts to Your Local Water Quality

The smart touch display puts you in control, allowing automatic flushing intervals of 7, 15, or 30 days depending on your local water conditions. A manual flush option is also available for immediate cleaning with a single touch when needed — adapting to your specific needs.

Clearer Water Throughout the Entire Home

With balanced 40 μm filtration precision, the system captures sediment, rust, and suspended particles before they reach your faucets, showerheads, and appliances. The result is noticeably cleaner water throughout your home — protecting washing machines, water heaters, and plumbing from sediment buildup while reducing unpleasant tastes and odours.

Built to Last with Minimal Ongoing Cost

The reusable 316L stainless steel filter mesh offers excellent corrosion resistance and long-term durability, eliminating the need for routine disposable cartridge replacement. Backed by rigorous testing including 120,000 water-hammer cycles and −30°C low-temperature material evaluation, the Lunde Series provides reliable protection for years to come — with lower maintenance costs and less waste.

Core Technologies & Benefits

The Lunde Series brings together five proven engineering solutions to achieve efficient, intelligent, and reliable residential water filtration.

1. 316L Stainless Steel Filter Mesh: The precision-woven 316L stainless steel mesh captures sediment, rust, and suspended particles. The corrosion-resistant material withstands repeated flushing without degradation, eliminating disposable cartridge replacement.

2. intelligent 3-in-1 Cleaning Assembly: The cleaning assembly integrates a forward-flush valve, a siphon backwashing channel, and a 360°internal scraper. The scraper loosens attached impurities while backwashing reverses water flow to flush them out — restoring mesh cleanliness without disassembly.

3. Smart Control Module with Touch Display: The electronic control module, operated via a touch display, allows automatic flushing intervals of 7, 15, or 30 days. A manual flush button provides on-demand cleaning, while the module tracks interval status for maintenance convenience.

4. Isolated Waterway and Electrical Compartment Design: The internal waterway is structurally isolated from the electrical compartment, preventing water contact with electronic components. The sealed electrical compartment ensures safe and reliable operation.

5. High-Flow Housing with Durable Construction: The housing incorporates an optimized internal bypass channel and large-diameter ports to minimize pressure loss. Reinforced sealing rings prevent leakage, and the housing has passed 120,000 water-hammer cycles and −30°C material testing for long-term reliability.
Reliable Filtration

-Filtration Flow Rate: 6.0 m³/h — supports simultaneous water use across multiple household water points without significant pressure loss
-Rated Total Purified Water Capacity: 1,000 m³ — ensures long-lasting filtration performance before maintenance is required
-Filtration Precision: 40 μm — balanced pore size captures sediment and rust while resisting premature clogging
-Structural Validation: Verified through 120,000 water-hammer cycles, structural pressure testing, and −30°C low-temperature material evaluation

Installation Requirements

For reliable installation, position the pre-filter at the main water entry point to protect the entire household water system from sediment, rust, and suspended particles.

-Position the unit at least 10 cm away from the wall
-Reserve approximately 300 mm of clearance beneath the drain outlet
-Confirm water-flow direction before installation
-Install the required inlet, outlet, and bypass valves
-Operating pressure range: 0.15–1.0 MPa (if pressure is too high, install a pressure reducing valve)
-Operating temperature range: 5–38°C

The compact footprint (170 × 92 × 307 mm) allows flexible placement in various technical spaces, while the clean, professional aesthetic blends discreetly into any environment.
