Modulo Clean is the world’s most complete series of linear drains, which require almost no cleaning! Thanks to its improved siphon, incorporating our Dryphon® technology, it is now more powerful and convenient. The Dryphon® system blocks any odour from the waste piping, without using water. This provides higher drainage capacity (60 l/min) and requires less maintenance. Both Dryphon® and a standard water seal are included, so you can decide yourself which you prefer.
