The ESSMANN GULLY with screw flange series provides a loose flange design that allows roof sheeting with a minimum thickness of 1.5 mm to be connected by the customer by means of a screw flange. The screw flange and the screws supplied are made of stainless steel and enable the different components to be screwed together securely and accurately through a fixture provided in the screw flange.
ESSMANN gullies with screw flange, vertical version
are available in standard sizes DN 70, 100, 125 and 150. The gullies can be designed in unheated and heated versions, with the latter featuring a 230 V resistance heater.
All gully bodies are made of extremely impact-resistant polypropylene (PP) and are double walled for heat insulation. To exclude the possibility of backflow in accordance with DIN, the upper section of the inlet cup contains a groove into which a roll ring is inserted when an extension unit is attached. Fixing the roll ring into the groove ensures that the seal cannot slip out of position." |
