Overview of Davey's CrystalClear ER Series Media Filter
The CrystalClear ER Media Filter is a superior quality and seamless one-piece vessel which has been manufactured with precision filament winding machine and continuous strands of high quality fibreglass filament.
The CrystalClear ER Media Filter uses ‘depth filtration,’ where dirt is pushed through the filter bed and trapped in tiny spaces between the filter media particles. This process allows clean water to flow through the filter’s laterals and exit via the Multiport valve.
Features & Benefits:
- Seamless one piece fibreglass tank, manufactured with precision filament winding machine providing long and reliable working life.
- Specially designed fish tail laterals saves water, energy and time.
- Water saving 30% reduction in backwash time with improved hydraulic efficiency.
- Energy saving hydraulic efficiency halves the backwash flow rate, allowing for low powered energy efficient pumping options.
- Enhanced water clarify from lower flow rate.
- Liquid filled pressure gauge makes it easy to see when backwashing is required.
- Built-in waste port sight glass for high visibility of water during backwashing.
- Up to 350 kpa operating pressure.
- Suitable for sand, Zelbrite and glass media.

Energy Efficient & Water Saving Lateral System
Water Saving: Designed with a “Fish Tail” lateral system that provides superior coverage of the filter bed. Fish Tail laterals improve filtration and backwashing efficiency, significantly reducing backwash time and providing water saving of up to 30%
Energy Saving: The hydraulic efficiency of the “Fish Tail” laterals halves the backwash flow rate, allowing for low powered energy efficient pumping options
Clearer Water: a decreased flow rate offers the dual advantage of boosting filtration effectiveness and significantly improving pool water clarity.
Maximum Operating Pressure:
350kPA – DCM2440 & DCM2450
250kPA – DCM2850, DCM3250 & DCM3650
Applications:
- Ideal for inground and above ground pools.
- Suitable for salt, mineral salt and fresh water pools.
- Models suitable for pools up to 180,000 litres.
Structure:
- Quality 6-way multiport valve, integrated sight glass and liquid filled pressure gauge for optimum filter control.
- Robust barrel unions for easy installation and maintenance.
- Cylindrical shape provides the most efficient filtration operation and up to 350 kPa operating pressure.
- Superior quality and seamless onepiece vessel, no welds, or no seams or special tank linings that can cause corrosion or electrolysis.
- Long life UV stabilised, filament wound injection molded or fibreglass tank.
- Large media area means better filtration with high efficiency.
- Specially designed ‘FISH TAIL” laterals reduce flow rates allowing more efficient pumping and backflow operation.
- 40 or 50 Inlet and Outlet available.
