The AQUAEL brand stands for innovation in the field of filter technology. The many useful details of the brand's various internal and external filters are well known. For example, the AQUAEL Ultramax is the only filter on the market with a separate flap for the pre-filter. This makes it possible to change the pre-filter sponge without dismantling the pump head. The special feature of the AQUAEL Multikani is that the filter can be extended during operation. Not even the pump needs to be switched off. However, AQUAEL external filters not only stand for many useful details, they also stand for quality, manufactured in Europe, and for a long service life.
