Lacron Top Mount Filters
The Sureflow is the largest selling and most popular residential pool filter sold and installed in Britain for more than 25 years. Over a quarter of a million have been commissioned. The LSR range is ideally suited to permanent in-ground residential indoor or outdoor pools.
The main tank structure is made from extremely hard wearing (injection moulded) glass reinforced polyester. A smooth high gloss internal and external finish ensures a free flow and easy cleaning.
Lacron filters come complete with multiport & pressure gauge.
These filters are capable of being filled solely with filter sand for domestic filters, the use of Pea Gravel is normally for commercial installations.
The use of Pea gravel is primarily to allow a more even flow around the bottom of the filter, and reduce bacterial growth in the dead spot of the filter & increase the effectiveness of the backwash process, but due to the medium to high flow rate sand filters used for domestic pool, this is not necessary. If however these filters are to be used in a commecial environment, then pea gravel is recommended.
Should you wish to order the pea gravel for your filter, please look at the media table below to order the required amount of sand & gravel for your size of filter.
Always fill you filter 1/3 full of water before filling with any filter media, as this will help to lessen the impact of the media hitting the fragile laterals in the bottom of the filter. If you are using Pea Gravel, you must ensure that the gravel forms a level layer at the bottom of the filter first, and only just covers the laterals, if you over fill with Pea Gravel you will reduce the efficiency of your filter by reducing the depth & area of filtration available.
18" filter requires 75kg's of filter sand
