The new and improved Laguna Pressure-Flo 4000 pressurized pond filter eliminates green water and kills algae. The Laguna Pressure Flo 4000 provides mechanical filtration coupled with a powerful UVC sterilizer to produce a clear, clean and healthy pond environment for ponds up to 4000 gallons.
Simple to install and easy to maintain and clean, Laguna Pressure Flo filters are the heart that will keep your pond beautiful all season long.
The new Laguna Pressure Flo filters include a variety of improvements to simplify the maintenance process and provide more powerful filtration. Starting with the filter handles and diverter valve, each has been re-designed and strengthened. The cleaning handles now feature an ergonomically designed grip with re-enforced brush connections. The diverter valve has been re-shaped and enlarged to accommodate an improved cleaning indicator system and makes the patented Backwash Cleaning System easier to use. Yearly UV bulb maintenance has been simplified by improvements to UVC-Head; the screws used to attach the head to the filter unit are permanently connected to the UVC head. No more misplacing or losing screws during maintenance.
