Mining ducts
Web[When ducting is attached to the inlet, outlet, or both inlet and outlet, of a fan, its performance is changed] Fans are classified according to the four types of installation: Type A - Free inlet, Free outlet, Type B - Free inlet, Ducted outlet, Type C - Ducted inlet, Free outlet, Type D - Ducted inlet, Ducted outlet. Web• Where possible, set up payoff reel on same side of manhole as the duct so that the cable makes a “C” shaped curve from the reel to the duct entry. E.3 Equipment and Materials E.3.1 Ribbed or corrugated inner-duct provides lower friction coefficients between the fiber optic cable and the duct wall, thus enabling longer pulls.
