SABUG syphon shaft DN 300

System manhole for hydraulic odor shut-off of sewage pipes.

A wide variety of wastewater collects in wastewater pipes. As a result, not insignificant odor nuisances can arise. To prevent these odors from escaping at the openings of the sewage system, most drains of rainwater or fecal-free sewage are equipped with so-called odor traps in the form of water traps. However, this is not possible for all components. SABUG offers the solution in the form of a syphon shaft which works reliably as a central odor trap.

Assembly Notice:
The shaft is installed and compacted in layers in accordance with DIN EN 1610.
The cast-in-place concrete frame is constructed on site under the cover so that no traffic loads act on the shaft.

The shaft can be easily shortened on site using a standard saw, or extended in height using a shaft extension.

Connections directly weldable with the IP-plus welding system!
