The AC Filter is a traditional automatic backwashing system developed for coarse and fine water filtration.
It is especially designed to handle the nature and volume of solids in seawater, primarily used for oilfield injection or in demanding applications like pre-treatment of water and wastewater filtration.
Thanks to its features, reliability, and Filtrex experience, the AC filter is also adopted in offshore installations such as the North Sea. The AC can be tailor-made using any exotic material and adhering to the most stringent global regulations.
The AC Filter offers a large filtration area using a filtration media consisting of candle bundles assembled in a tube plate. This design provides a higher specific flux rate in a compact and lightweight unit.
The wedge wire filter surface, constructed in a rugged design, offers high mechanical strength, ensuring durability and long-term performance.
The rotating backwash mechanism uses low-friction nozzles that self-load under pressure, minimizing wear from heavy suspended sand. This reduces drag strain on the backwash arms, lowering the load on the motor and gearbox, while ensuring easy inspection of the internals through the hand hole.
The AC Filter requires minimal maintenance, even after over 20 years of continuous use. Should dismantling be necessary, the process is quick and simple. The top cover can be easily removed to extract individual candles or the entire bundle assembly, following the best plant maintenance procedures.
