Lyra Top Mount Sand Filter – 8 m³/h (400 mm)
The Lyra Top Mount Sand Filter is designed to deliver clear and hygienic water with consistent and reliable performance. Featuring a 1.5″ top-mounted multiport valve, it allows easy operation for filtration, backwashing, rinsing, and routine maintenance.

With a flow rate of 8 m³/h, a 400 mm (16″) tank diameter, and efficient filtration performance, this filter effectively removes dirt and suspended particles from the water. Its compact, corrosion-resistant construction ensures durability, easy installation, and low maintenance.

Ideal for swimming pools, fountains, and decorative water features, the Lyra sand filter provides dependable water filtration in a user-friendly design.

Key Highlights

• Flow rate: 8 m³/h
• 1.5″ top-mounted multiport valve
• Tank diameter: Ø 400 mm (16″)
• Durable, corrosion-resistant, and easy-to-maintain design

1. Efficient Filtration

   • Uses silica sand or glass media to trap dirt, debris, and contaminants as small as 20–40 microns.

   • Ideal for removing organic matter, algae, and fine particles.

2. Durable Construction

   • Made from high-strength, corrosion-resistant materials (like fiberglass-reinforced plastic or polyethylene) to withstand outdoor weather and pool chemicals.

3. Multiport Valve System

   • Typically includes a 6-way valve for easy control:

     • Filter – normal operation

     • Backwash – cleans the sand bed

     • Rinse – resets the filter after backwashing

     • Waste – bypasses filter to drain

     • Recirculate – bypasses filter to circulate water

     • Closed – shuts off water flow

4. Easy Maintenance

   • Requires backwashing (flushing out dirty water) periodically.

   • Sand needs to be replaced every 3–5 years depending on usage.

5. High Flow Rate

   • Supports high gallons-per-minute (GPM) flow, making it suitable for large residential or commercial pools.

6. Low Operating Cost

   • Energy-efficient with minimal maintenance compared to cartridge filters.

   • Does not require frequent replacement of filter media.

7. Versatile Sizes

   • Available in a wide range of sizes to suit small residential pools to large commercial installations.

8. Pressure Gauge

   • Built-in pressure gauge to monitor the system and indicate when backwashing is needed.

9. Top or Side Mount Options

   • Different configurations available for plumbing flexibility.
