Theseall-in-one filters provide mechanical, biological* and UV sterilization and are designed to work in tandem with a solidshandling pumps such as Laguna’s Max-Flo. This great inline filter unit can be added to most pond installations by simplycutting a waterline from the pond pump to an existing water feature, like waterfalls or streams. The Click-Fit connectershelp make installation quick and easy.
The Laguna Pressure-Flo Filters also feature a revolutionary Backwash-Cleaning System that easily cleans the entiresurface of the foam filters without opening the filter. This patent-pending system is one of a kind. Backwash cleaningcan be done easily and comfortably in a few minutes without opening the lid. This feature ensures that the filtersperform at optimal levels for many days and prolongs the time between full maintenance sessions. An easy-viewcleaning indicator signals when it’s time to perform backwash cleaning.The Laguna Pressure-Flo Filters are for use in freshwater aquariums only.*Pressure-Flo 700 does NOT have a biological filtration chamber.Four Models of Laguna Pressure-FloUniversal Click-Fit fast coupling for ¾-inch, 1-inch, and 1 ¼-inch hosing.Intended UseThe Laguna Pressure-Flo filter is a sealed pressure filter with an integrated UV-C sterilizer designed toprovide mechanical and biological filtration in outdoor fresh water ornamental ponds with a temperature from 39.2° to95° Fahrenheit, with or without fish. The purpose of mechanical filtration is to trap and accumulate debris and wastematerial coming from the pond. The purpose of biological filtration is to convert toxic by-products of fish metabolismand other organic waste into much less harmful substances. The purpose of UV-C filtration is to inhibit single-celledalgae growth. All ponds will benefit fromthe addition of a filtration system. A good filtration system, such as the Laguna Pressure Flo ensures that the waterquality of the pond will remain clear of impurities which can accumulate and create a cloudy or toxic environment forpond plants and fish. The Laguna Pressure Flo will provide your fish with a clean and clear environment to live a healthylife in.How Pressure-Flo Filters WorkPressure-Flo filters are designed to provide three important water filtrationoperations that are essential for keeping pond water clear and healthy: mechanical and biological filtration, and UVCsterilization. The filters are designed to work in tandem with a solids handling pump. For best results, use a LagunaMax-Flo circulating pump. With the filter connected to the outlet of a pump, water enters the unit through the waterinlet. It is then forced to pass through the mechanical filtration stage, consisting of foam filters that intercept and trapdirt and debris. Next, water reaches the biological filtration* chamber where it comes into contact with beneficial
bacteria. Finally, dirt-free water passes along the UV-C lamp unit, where it is exposed to ultraviolet rays that inhibitalgae growth and green water. Water then returns to the pond through the outlet.Backwash-Cleaning SystemDuring operation, coarse debris is captured at the surface of the foam filters. As a result, sooner or later depending onpond conditions, the external surface of the foam filters will clog and hinder proper filtration, because of reduced waterflow. The limited water flow through the foam filters reduces the effectiveness of both the biological and UV-C filtration.This condition can easily be detected thanks to the cleaning indicator on top of the filter unit. Pressure-Flo filters feature a unique Backwash-Cleaning System that completelycleans the entire surface of the mechanical foam filters without opening the filter or shutting off the pond’s pump. TheBackwash-Cleaning is performed by two foam filter scrapers, which are operated by using the plungers located on top ofthe filter unit’s lid. While the pond pump is running, simply turn the backwash valve to the backwash position and beginpulling the plungers one at a time up and down until the water being discharged is clean. After cleaning the filter willperform at optimal levels for many days. The Backwash-Cleaning System prolongs the time between filter breakdownmaintenance sessions and in most cases only end of season breakdown cleaning will be necessary.Pond Tip:When backwashing or performing maintenance, use the backwash water in your garden - its an excellent naturalfertilizer! Unlike other pressurized filters, water travels through mechanical filtration (where large particles are filteredout) before entering the UV chamber, making the UV sterilization process much more efficient.Cleaning IndicatorThis unit features a cleaning indicator, which lets you know when the filter needs backwashing or cleaning. The redindicator height is approximately proportional to the filter clogging level. When the red indicator is low, the filter is clean,when the red indicator is at the top of its stroke, the filter needs cleaning.The cleaning indicator may be affected by many variables, such as waterfall height and pump performance. Itsoperating characteristics have been calibrated according to specific application conditions. Different applicationconditions may lead to different results.Breakdown of Filters
