💧 Lacron Finaflow ZZ3260NS 30″ Complete Sand Filter with Valve & Gauge
Professional deep bed filtration for larger pools, ready to install
🌊 Product Overview
The Lacron Finaflow ZZ3260NS is the complete 30″ (760mm) deep bed sand filter system, delivered ready for installation with factory-matched 6-way multiport valve and pressure gauge. This turnkey package combines the proven Finaflow tank with all necessary valve components, eliminating specification complexity and ensuring guaranteed component compatibility for professional-grade results.
Delivering a robust 20.0m³/h flow rate through 2″ connections, the ZZ3260NS provides 48% more filtration capacity than its 24″ sibling whilst maintaining the signature deep bed technology that sets Finaflow apart. The minimum 1-metre media depth ensures extended water contact time, capturing finer particles and colloidal substances that pass straight through conventional shallow-bed filters – the result is noticeably clearer water with reduced chemical demand.
The complete package includes the commercial-grade GRP tank with side hatch for rapid media changes, sight glass for visual bed inspection, and connecting unions for straightforward installation. Ideal for larger residential pools, holiday let properties, and light commercial applications operating with warmer water and higher bather loads. With Lacron’s 35+ year industry track record and Waterco Group backing, the ZZ3260NS represents the professional choice for pools up to 160,000 litres demanding superior water clarity without the hassle of sourcing separate components.

🔄 Maintenance Guide
Routine Maintenance Schedule:
| Task | Frequency | Method |
|---|---|---|
| Check pressure gauge | Weekly | Note baseline reading when clean |
| Visual bed inspection | Weekly | Check through sight glass during operation |
| Backwash filter | When pressure rises 0.5-0.7 bar | Run until sight glass shows clear water |
| Rinse after backwash | After every backwash | 60-90 seconds to settle media |
| Inspect valve seals | Seasonally | Replace if worn or leaking |
| Check media level | Annually | Top up if low via service hatch |
| Full media replacement | Every 5-7 years (sand) | Access via service hatch |
Pressure Gauge Guide:
📊 Clean filter baseline: 0.8-1.2 bar (typical)
📊 Backwash recommended: 0.5-0.7 bar above baseline
📊 Maximum operating: 2.5 bar
Deep Bed Advantage: The 1-metre minimum bed depth provides significantly greater dirt-holding capacity than standard filters, meaning longer intervals between backwashes and reduced water wastage.
Using the Integrated Pressure Gauge: The included pressure gauge is your primary indicator for filter condition:
- Note the pressure reading when the filter is freshly cleaned (baseline)
- Monitor weekly – pressure will gradually increase as debris accumulates
- When pressure rises 0.5-0.7 bar above baseline, it’s time to backwash
- After backwash and rinse, pressure should return close to baseline
Sand Dump Port: The ZZ3260NS features a purpose-designed lower outlet (sand dump port) for efficient media removal during changes, significantly reducing maintenance time.
Winterisation (Essential for UK Climate):
- Switch off pump and allow system to depressurise
- Set multiport valve to “Winterise” position or between settings
- Drain filter tank completely via manual drain
- Open air vent to assist complete drainage
- Remove and store drain plug safely
- Leave multiport valve in intermediate position to prevent seal compression
- Cover filter or relocate to frost-free storage if possible
⚠️ Critical: The deep media bed retains significant water. Ensure complete drainage before freezing conditions to prevent tank damage.
🪨 Filter Media Information
The Lacron Finaflow ZZ3260NS’s deep bed design is optimised for use with specific filter media to achieve maximum performance.
Recommended Media Types:
| Media Type | Size | Filtration Rating | Benefits |
|---|---|---|---|
| Lacronite (Zeolite) | As supplied | 3-5 microns | Superior clarity, reduced chemicals, longer life |
| Filter Sand | 0.5-1.4mm (16/30 grade) | 20-40 microns | Economical, proven performance |
| Glass Media | 0.5-1.0mm | 5-15 microns | Finer filtration, eco-friendly |
Media Capacity: Contact Parts4Tubs for specific media quantities for the ZZ3260NS deep bed configuration.
💡 Lacronite Advantages: Lacron specifically recommends their Lacronite zeolite media which offers superior water clarity, remarkable dirt retention, reduced backwashing frequency, lower chemical costs, and improved bather comfort.
Graded Bed Option: The deep bed design allows for graded media installation with different grain sizes to achieve specific filtration fineness – consult Lacron documentation for recommended configurations.
Signs Media Needs Replacing:
- Persistently cloudy water despite correct chemical balance
- Shortened filter cycles requiring frequent backwashing
- Visible media particles in pool returns
- Media channelling visible through sight glass
- Increased chemical consumption without improved clarity
Media Change Access: The ZZ3260NS features both a dedicated service hatch and sand dump port for rapid media removal, significantly reducing maintenance time compared to filters requiring complete disassembly.

⚙️ Valve Positions & Functions
The included 6-way multiport valve provides complete control over all filtration and maintenance operations:
| Position | Function | When to Use |
|---|---|---|
| Filter | Normal filtration mode | Daily operation – water flows through media and returns to pool |
| Backwash | Reverses flow to clean media | When pressure gauge rises 0.5-0.7 bar above baseline |
| Rinse | Settles media after backwash | 60-90 seconds after every backwash cycle |
| Waste | Bypasses filter, drains to waste | Vacuuming heavy debris, lowering water level |
| Recirculate | Bypasses filter, returns to pool | Distributing chemicals, troubleshooting |
| Closed | Stops all water flow | Maintenance, winterisation |
⚠️ Important: Always switch off the pump before changing valve positions to prevent damage to the valve and seals.

❓ Frequently Asked Questions
Q: What size pool will this filter handle? A: The ZZ3260NS is suitable for pools up to 160,000 litres with an 8-hour turnover, or optimally up to 120,000 litres with a 6-hour turnover.
Q: What’s included in the package? A: The ZZ3260NS includes the 30″ Finaflow deep bed tank with side hatch and sight glass, 6-way side-mount multiport valve, pressure gauge, connecting unions, and filter base. It’s a complete, ready-to-install system.
Q: What’s the difference between this and the FF30416? A: The FF30416 is the tank-only version, while the ZZ3260NS is the complete package including valve and gauge. Both use the same 30″ Finaflow tank with identical filtration performance.
Q: What connection size does this filter use? A: The ZZ3260NS uses 2″ (63mm) connections – larger than the 24″ model’s 1.5″ fittings. This reduces friction loss and suits larger pump installations.
Q: How often do I need to backwash? A: Backwash when the pressure gauge reads 0.5-0.7 bar above your clean baseline. The deep bed design provides greater dirt-holding capacity, typically allowing longer intervals between backwashes.
Q: What filter media should I use? A: Lacron recommends either Lacronite (zeolite) for superior 3-5 micron filtration, or 16/30 grade sand (0.5-1.4mm) for standard 20-40 micron filtration. Glass media is also compatible.
Q: What is the advantage of the deep bed design? A: The minimum 1-metre media depth provides extended water contact time, capturing finer particles and colloidal substances that pass through shallow-bed filters. This results in noticeably clearer water and reduced chemical demand.
Q: Is this suitable for commercial use? A: The Finaflow range is designed for commercial and domestic pools, particularly those with warmer water and higher bather loads. For regulated commercial pools, verify compliance with PWTAG guidelines.
Q: What pump do I need? A: Pair with a pump delivering between 15.0-20.0m³/h through 2″ pipework. Never exceed the filter’s maximum flow rate.
Q: What warranty is included? A: Lacron products are backed by manufacturer warranty. Contact Parts4Tubs for full warranty terms and conditions.
