coalsi Street- channel filter

The coalsi Street- channel filter is the combined filter solution for odourous gas emissions from canals, allowing a completely trouble- free surface drainage on the same time. Various installation options fit in almost all street manholes.

Coalsi Street- channel filter

Basic principle

Whether for street manholes or side inlets – coalsi street-channel filters eliminate odours effectively without impact on surface drainage. Based on the patented siphon technique, the retention capacity of the drainage system for waste water is not reduced. The system simultaneously enables an unobstructed water drainage and a uniform distribution of air flow through the activated carbon mats.


  • Largest filter area possible
  • Safe and easy handling
  • Installation options suitable for a variety of road gullies
  • no manual irrigation necessary, even during long dry season
  • Maximized operating life time through combined filter solutions (chemical, physical and biological)
