4-68 Industrial Blower Working process
4-68 industrial blower operates on the centrifugal principle. Firstly from environment the Air enters axially into the impeller hub and where the rapidly rotating impeller blades accelerate the air radially outward. This velocity is then converted into static pressure within the scroll shaped housing which delivering uniform with high-pressure air output suitable for ventilation, exhaust and material conveying systems.
Key Mechanism Steps:
Inlet: here inside the Air enters through the center of the blower.
Impeller Action: The action happened because of kinetic energy is imparted by the impeller.
Energy Conversion: Here the Velocity is transformed into pressure via the volute casing.
Outlet: Highpressure air or gas exits through the discharge duct.
