The AF filter presses from AQUACHEM are a further development of conventional chamber filter presses, which have been tried and tested in the industry for over a century. However, due to the degree of automation required and the increase in efficiency necessary nowadays, the technology we have had up until now is often no longer up to date. The design of the AF filter presses is based on the optimum interplay of the ?? individual assemblies of the filter press to ensure reliable, efficient and permanent operation without personnel being present. The automated flexibility of the product enables autonomous adjustment to changing conditions, such as concentration or even specific filter properties. We guarantee these properties and also availability. This is only possible because AQUACHEM and the AF-series possess the knowledge, an intelligent control system and the technology for maximum flexibility. Yes, this is a product with unique selling points – test it out yourself.

Our testing filter presses for hire are available in various sizes. Whether in a container or as a mobile filter press, we're sure to find the right solution for you. Set-up and connection of the systems is easy to perform, and we are of course ready to assist you with commissioning.

The AQUACHEM LCM 320 (pocket press membrane) is ideal for mobile deployment on site on a suitable trolley and can be operated with up to 15 bar loading and 15 bar membrane squeezing.
