OASE Secure Flow 3000

• Required if pre-filtered water is not available
• Additional protection contamination of the actual Oase PhosLess cartridges
• Filled with ultra-smooth glass beads with excellent back-washing properties
• Easy cleaning of the pre-filter cartridge – to back flush just reverse the flow direction
• Can be combined with energy-saving pond pumps
• Apply a 4m delivery head when used in conjunction with a PhosLess Flow or PhosLess Power Flow

The Oase Secure Flow 3000 has been specially designed to provide an in-line pre-filter cartridge for the Oase Phosless Flow 3000 and Oase Phosless Power Flow 3000. The Secure Flow must be used when pre-filtered water is not available.

The Secure Flow pre-filter is packed full of ultra-smooth glass beads which filter out debris, preventing any contamination of the PhosLess cartridges. The Secure Flow can be easily cleaned thanks to the excellent back-flush characteristics of the glass beads, simply change the flow direction through the unit to black flush.

Installation Note:
When the Secure Flow is installed in conjunction with either a PhosLess Flow or PhoLess Power Flow a 4m delivery head must be taken into account when choosing a suitable pump.
