D Type Centrifugal Ventilator Fan

China D Type Centrifugal Ventilator Fan from Hebei Ketong, mainly used for medium-pressure gas conveying in industrial production and ventilation systems, featuring a belt-driven structure (with motor installed on a separate base, connected to the fan impeller via a V-belt and pulley) that allows flexible adjustment of air volume and pressure by changing belt speed, making it highly adaptable to different working condition requirements.
It is generally installed at the air supply end of industrial workshop ventilation systems, the exhaust section of mechanical processing dust collection equipment, the air circulation port of paint spraying workshops, or the gas conveying pipeline of food drying production lines, responsible for conveying clean air, low-concentration dust-laden gas, solvent-containing exhaust gas (with low corrosiveness), or hot air for drying processes.
These fans are typically supplied to machinery manufacturing plants, automotive assembly plants, furniture production enterprises, food processing plants, or industrial ventilation engineering companies.This D Type Centrifugal Ventilator Fan can flexibly match different air volume and pressure demands through its belt-driven adjustment design, fully meeting the medium-pressure gas conveying and ventilation needs of industrial production links such as mechanical processing, surface treatment, and food drying, while strictly complying with the national industrial ventilation safety standards and workshop air quality emission specifications.

Product Features

1.Efficient Engine Design: The engine is the core of the system. The D Type Centrifugal Ventilator Fan employs blade shapes specifically designed for low-speed, high-pressure environments, while D-type fans typically feature robust inclined blades or are engineered to enhance efficiency and reduce axial resistance, contributing to stable operation.
2.Durable Drive System: The D-type engine incorporates an independent auxiliary bearing assembly designed for heavy-duty applications. This configuration enables efficient high-torque output, making it an ideal choice for driving high-power motors required in high-pressure applications.
3.Adjustable Housing and Storage: Scroll-type housings are constructed from thick steel plates for long-lasting durability. Housings generally feature a balanced intake design, which is adjusted to ensure optimal airflow into the engine, thereby improving performance.
4.Consistent Rotor Assembly: The rotor is a critical component (engine and rotor configuration). After manufacturing, rotors undergo precise dynamic balancing. This process minimizes residual misalignment, resulting in low vibration levels (e.g., motor amplitude ≤0.04mm) and quiet, reliable operation.

Product Application

D-Center fans can be widely applied in the following industries: industrial and metallurgical furnaces; transportation and material handling; chemical and processing industries; building environments and HVAC systems.
