Description
Magna-Flo Top Mount Fibreglass Sand Filter
Bobbin-wound fibreglass construction engineered for Australian conditions
The Magnaflo Top Mount is a purpose-built media filter designed for the Australian market, manufactured from long-lasting, non-corrosive fibreglass and resin using bobbin-wound automatic technology with UV-resistant composites. This construction allows the filter to withstand extreme weather conditions with no corrosion, delivering a long working life backed by a robust, ageless design.
A balanced internal hydraulic design maintains even flow through the media bed for maximum filtration performance, while a large-capacity media bed and manual 6-way multiport valve assembly extend filter cycles and reduce maintenance time. The range covers small residential pools through to large-volume commercial applications, with both 40 mm and 50 mm multiport valve options across mid-size tanks to match your plumbing and pump configuration.
Key Features
- Bobbin-wound fibreglass tank – non-corrosive, chemically resistant and UV-stable for harsh Australian conditions.
- Glassy gel-coat finish – stylish, smooth exterior that resists fading and weathering.
- Balanced internal hydraulic design for even flow distribution and maximum filtration efficiency.
- Manual 6-way multiport valve – filter / backwash / rinse / waste / recirculate / closed.
- 40 mm and 50 mm valve options on the 25” and 28” tanks to suit different plumbing and pump setups.
- Large-capacity media bed – longer filter cycles and reduced maintenance frequency.
- Compatible with 1 mm silica sand or glass filter media – capacities listed per model.
- Suited to swimming pools, marine parks, aquaculture, and industrial water treatment.

Frequently Asked Questions
Q1: What media can I use in the Magnaflo Top Mount?
The Magnaflo tank is engineered for 1 mm silica sand or glass filter media. Required quantities (in kg) for each tank size are listed in the specification table above.
Q2: How do I select the correct model for my pool?
Match the filter to your pump using the Recommended Pump Size column. Oversizing the filter relative to the pump generally improves filtration quality, extends backwash intervals and reduces head-loss — when in doubt, size up.
Q3: What’s the difference between the 40 mm and 50 mm multiport valve options?
The 25” and 28” tanks are available with either a 40 mm or 50 mm multiport valve. The 50 mm valve reduces hydraulic restriction through the filter, which generally improves flow efficiency and pairs well with higher-flow or variable-speed pumps. The 40 mm valve is the simpler, direct retrofit for existing 40 mm plumbing setups.
Q4: Why does the glass media weight differ from sand?
Glass filter media has a lower bulk density than silica sand, so a smaller weight fills the same tank volume. Both medias deliver effective depth-bed filtration; glass typically offers finer particle capture and longer service life.
Q5: What is included with the filter?
Each Magnaflo Top Mount tank ships with a manual 6-way multiport valve (filter, backwash, rinse, waste, recirculate, closed) in your selected size. Filter media is sold separately.
Q6: Is the tank suitable for harsh weather?
Yes. The bobbin-wound fibreglass and resin construction with UV-resistant composites is designed to resist corrosion and weathering, making it well suited to Australian outdoor pool installations.
