The Laguna Pressure-Flo pressurised pond filter provides important water filtration functions that are essential for everyday pond maintenance: mechanical and biological filtration, as well as UVC sterilisation, which is great for keeping your pond algae free.
The Laguna Pressure-Flo pond filter features a revolutionary patented Easy Clean Backwash-Cleaning System that completely cleans the entire surface of the foam filters, and has had significant improvements so is now even easier to use than before.
Pressure-Flo is designed to work in tandem with a solids handling pump, ideally a Laguna Max-Flo waterfall and filter pump. With the filter connected to the pump, water enters the unit through a water inlet. It then passes through the mechanical filtration stage, consisting of highly durable foam filters that intercept and trap dirt and debris.
Next, water enters a biological filtration chamber where it comes into contact with BioRock biological filter media* which remove ammonia, and harbour beneficial bacteria keeping the water healthy for plants and fish. Dirt-free water then passes along an integrated UV-C lamp, where it is exposed to ultraviolet rays that inhibit the growth of algae. Water finally returns to the pond thoroughly cleansed.
This patented system is the only one of its kind. Backwash cleaning can easily and comfortably be completed in a few minutes without opening the lid. This feature ensures that the filter performs at optimal levels for many days and prolongs the time between full maintenance sessions. An easy-to-view cleaning indicator signals when it's time to perform backwash cleaning.
*Only foam filtration included with the Pressure Flo 3000 version (PT1715).
