Ventilation Ducts And Equipment

Natural ventilation systems generally do not need to set up equipment, main equipment of mechanical ventilation fan, duct or ducts, air valve, ventilation and dedusting equipment. L. classification of the fan Fan is for air flow ventilation system to provide power to overcome resistance loss during transportation of machinery and equipment. In the ventilation system is the most widely used in centrifugal fan and axial-flow ventilator. Centrifugal fan impeller, housings, machine shafts, inlet, exhaust and other parts. As the impeller rotates, leaves the gas obtained impeller centrifugal force, gas follows the blade under the action of centrifugal force constant inflow and outflow.
