Davey Microlene ETFN12 12" Manual Backwash pH Neutralising Filter with Sacrificial Neutrafil Bed

Higher flow acidic water correction comes from the Davey ETFN12, a manual backwash neutralising filter designed for elevated pH correction from bore and rainwater supplies.

A larger polyglass structural tank with fibreglass wrapping contains sacrificial Neutrafil media that dissolves to neutralise acidity. The manual rotary multi-port valve allows user-controlled backwashing and rinsing.

Pressures from 2.1 to 6.9 bar drive the system, delivering 40 to 70 L/min without electricity. The 25mm inlet and outlet ports connect to plumbing systems.

The 12 inch by 52 inch tank contains 60kg of Neutrafil media and 10kg of gravel foundation. Backwashing at 25 L/min prevents media compaction and maintains consistent flow.
