The siphon Typhon is positioned within the exhaust grill in support with the entire peripheral surface of a flange portasifone housed in fusion inside the frame of the grid. The flow of rain runoff is conveyed through appropriate gradients of the drain grate going to fill the tank and siphon protruding from the outer edge. The reservoir of the siphon is filled completely so that effectively prevents odors and gaseous formations, formed in the exhaust pipe below the cockpit, they can flow out. The particular guarantee of the siphon allows you to block the ascent of any gas formation underlying the structure of the cockpit. We recommend a periodic maintenance of the siphon (drain from soil, leaves, etc.. Than you have deposited inside).
