4-72 centrifugal fan
The 4-72 centrifugal fan is a high-efficiency and energy-saving centrifugal fan. Its airfoil-shaped blades, curved impeller front disk and cone-shaped inlet collector make the fan have excellent aerodynamic performance and play an important role in my country's economy. In the construction industry, it has been enduring for many years.
Application
Air supply for civil buildings
High efficiency and energy saving, airfoil blades, curved impeller front disk and tapered arc inlet collector, have good aerodynamic performance, balanced operation, small vibration and high efficiency
The ventilation effect is good. The 4-72 centrifugal fan has a good exhaust effect and is very suitable for use in duct exhaust or air supply.
Strong applicability
The 4-72 centrifugal fan is a fan commonly used in ducts to transport air. It can be used in places with corrosive, flammable and explosive gases.
Low noise
The 4-72 centrifugal fan adopts a reasonable impeller angle design based on air flow mechanics. During operation, there is no mechanical friction and the reasonable blade shape minimizes the noise; the noise generated by the 4-72 centrifugal fan It is high-frequency noise and can be soundproofed as long as there are obstacles.
