Laguna Pressure Pressurised Pond Filter Range for Ponds up to 21000L

The Laguna Pressure Flo 21000 Pressurised Pond Filter provides excellent pond filtration, combining both mechanical and biological filtration, with a powerful 36w UV clarifier. Suitable for ponds up to 4,000 litres the Pressure Flo 21000 Filter can be installed either in or above ground for simple and easy installation. The Laguna Pressure Flo 21000 Pond Filter comes backed with a 3 year warranty for peace of mind.

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.

The Laguna Pressure Flo Filter features a revolutionary patented Easy Clean Backwash-Cleaning System that easily cleans the soiled surfaces of the foam filters. This patented system is the only one of its kind. Backwash cleaning can easily and comfortably be completed in just a few minutes without opening the lid. This feature ensures that the filter performs at optimal levels for extended periods and prolongs the time between full maintenance sessions.

The Pressure Flo Filters are designed to work in tandem with a solids handling pump, ideally one of the Laguna Max-Flo waterfall and filter pumps. Depending on fish stocking and position the Pressure Flo 21000 is recommended for use with the Laguna Max Flo 16500 pump for both a light loading in shade or heavy loading in full sun.
