1 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. The cooing whee, patented by exodraft, aows the fan: y to work reiaby in continuous operation with temperatures up to 5 C y to work in peak temperatures of up to 7 C in 3 minutes 1 Capacitor and repair switch box 2 Conduit/cord 3 Motor 4 Motor housing 5 Motor pate 6 Bird screen 7 Base pate 8 Locking hande 9 Inet 1 Axia vane 11 Hinge 12 Capacitor (inside box) 13 Cooing whee Type Motor data Weight Dimensions (mm) RPM V Amps kw* kg A B C ø D E ø RSHT x 23,4, RSHT x 23,6, RSHT x 23 1,2, RSHT x 23 1,8, C.

The fan s capacity changes with the temperature of the fue gases. The correction of the capacity can be cacuated using the foowing equation: Ps = 2 Ps t x (273 + t) P s = static pressure 293 t = temperature measured in C C. F.
