The words durability and dependability best describe Calplas' HFS (Hydrostatic Filtration System) filters. In their manufacturing process, hand-lay-up glass-reinforced polyester is used, which is both lighter and more resilient than steel. Calplas filters in the HFS series are designed following EN 13121-3, the European standard that specifies requirements for the use of above-ground tanks and vessels made of glass-fibre-reinforced plastic (GRP).
 
Calplas HFS filters feature a large, transparent top cover, internal encapsulated steel reinforcements for added strength, and specially designed side walls for optimum water filtration and backwashing.

The Calplas AFM series offers the best performance on the market. AFM (Activated Filter Media) filters are bio-resistant and self-sterilising, preventing the growth of bacteria, which is essential for keeping the water clear and transparent.

Installing a Calplas AFM filter in your swimming pool promotes chlorine reduction and minimises the risk of infections caused by pathogenic organisms. One of its main advantages is its ability to reduce the presence of trihalomethanes (THMs), a group of volatile chemical compounds produced by the reaction of untreated organic matter with chlorine used for disinfection during the water purification process. THMs are potentially hazardous to health and the environment.

Using AFM pool filters is thus the ideal solution for those seeking pure, crystal-clear water and a swimming pool that is always ready for use.  

FlowVis® is the best ally for those looking for the most advanced and dependable flowmeter available on the market. FlowVis® provides exceptional performance thanks to a design specifically tailored to pools, spas, and fountains, allowing you to adjust the speed of water pumps and optimise filtration efficiency, thus reducing water consumption and saving energy.

Besgo pneumatic valves automate the backwashing of pool filters to remove contaminants that may have accumulated inside the swimming pool. Maximum operational safety is combined with minimal pressure drop and savings of 50-80% when compared to battery valves.

AFM® is a highly engineered product manufactured from a specific glass type and the best-performing filter media on the market thanks to its optimal mechanical filtration efficiency. AFM® filters are a direct replacement for sand, doubling the performance of sand filters, and capable of removing heavy metals from water and reducing the risk of bacterial and parasitic infections to an absolute minimum.
