These all-in-one filters provide mechanical, biological* and UV sterilization and are designed to work intandem with a solids handling pumps such as Laguna’s Max-Flo. This great inline filter unit can be added tomost pond installations by simply cutting a waterline from the pond pump to an existing water feature, likewaterfalls or streams. The Click-Fit connecters help make installation quick and easy.
The Laguna Pressure-Flo Filters also feature a revolutionary Backwash-Cleaning System that easily cleans theentire surface of the foam filters without opening the filter. This patent-pending system is one of a kind.Backwash cleaning can be done easily and comfortably in a few minutes without opening the lid. This featureensures that the filters perform at optimal levels for many days and prolongs the time between fullmaintenance sessions. An easy-view cleaning 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 sterilizerdesigned to provide mechanical and biological filtration in outdoor fresh water ornamental ponds with atemperature from 39.2° to 95° Fahrenheit, with or without fish. The purpose of mechanical filtration is to trapand accumulate debris and waste material coming from the pond. The purpose of biological filtration is toconvert toxic by-products of fish metabolism and other organic waste into much less harmful substances. Thepurpose of UV-C filtration is to inhibit single-celled algae growth. All ponds will benefit from theaddition 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 toxicenvironment for pond plants and fish. The Laguna Pressure Flo will provide your fish with a clean and clearenvironment to live a healthy life in.How Pressure-Flo Filters WorkPressure-Flo filters are designed to providethree important water filtration operations that are essential for keeping pond water clear and healthy:mechanical and biological filtration, and UVC sterilization. The filters are designed to work in tandem with asolids handling pump. For best results, use a Laguna Max-Flo circulating pump. With the filter connected to theoutlet of a pump, water enters the unit through the water inlet. It is then forced to pass through the mechanicalfiltration stage, consisting of foam filters that intercept and trap dirt and debris. Next, water reaches thebiological filtration* chamber where it comes into contact with beneficial bacteria. Finally, dirt-free waterpasses along the UV-C lamp unit, where it is exposed to ultraviolet rays that inhibit algae growth and greenwater. 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 laterdepending on pond conditions, the external surface of the foam filters will clog and hinder proper filtration,because of reduced water flow. The limited water flow through the foam filters reduces the effectiveness ofboth the biological and UV-C filtration. This condition can easily be detected thanks to the cleaning indicator ontop of the filter unit.
Pressure-Flo filters feature a unique Backwash-Cleaning System thatcompletely cleans the entire surface of the mechanical foam filters without opening the filter or shutting off thepond’s pump. The Backwash-Cleaning is performed by two foam filter scrapers, which are operated by usingthe plungers located on top of the filter unit’s lid. While the pond pump is running, simply turn the backwashvalve to the backwash position and begin pulling the plungers one at a time up and down until the water beingdischarged is clean. After cleaning the filter will perform at optimal levels for many days. TheBackwash-Cleaning System prolongs the time between filter breakdown maintenance sessions and in mostcases 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 excellentnatural fertilizer! Unlike other pressurized filters, water travels through mechanical filtration (where largeparticles are filtered out) before entering the UV chamber, making the UV sterilization process much moreefficient.Cleaning IndicatorThis unit features a cleaning indicator, which lets you know when the filter needs backwashing or cleaning. Thered indicator height is approximately proportional to the filter clogging level. When the red indicator is low, thefilter 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
