In order for the water in the pool to always be purified from various kinds of mechanical impurities, it is necessary to install a high-quality filter in a timely manner. ESPA pool filters are one such option. Their main advantage is high-quality performance.
They are made of fiberglass-reinforced and therefore extremely durable composite material. The main filter element in the structure is represented by a simple backfill. In this case, the backfill consists of sifted quartz sand, which is cleaned specifically for this purpose. Sand granules vary in size from 0.4 to 0.8 mm. They are delivered to production as separate granules, without sand.
In terms of technical characteristics, the filters are equipped with a platform, a pressure gauge, a special piping and a six-position valve, which helps to cope with the switching of the main operating modes. The recommended working pressure should not exceed 2 bar, although it is tested at the factory at 3 bar. This confirms their quality. ESPA pool filters can operate at high, medium and low loads. The first includes the strong influence of the environment and the presence of more than 6 users. The latter takes into account the extremely low content of water-polluting sources (trees, plants, etc.) and a small number of users (up to 4).
Thus, by choosing this type of filters, you can fully regulate their work, while counting on reliability and long service lines.
