Chimney fan RSHT High temperature resistant exodraft fan type RSHT is a speciay designed fue gas fan with horizonta discharge. It is fitted to the termination point of the chimney and there creating a negative pressure in the exhaust duct or in the chimney. The stainess stee and cast auminium housing ensure the RSHT very high corrosion resistantance. Technica data A D C E B A the screws and bots are made of stainess stee and so is the centrifuga impeer which has a very ow vibration eve.
