The centrifugal fan is a marvel of modern engineering, primarily composed of a sophisticated fan unit, essential auxiliaries, and an advanced control and monitoring system. The fan unit, the beating heart of this equipment, comprises the dynamic rotor part, including the precision-engineered impeller and robust main shaft, paired with the static marvels of the housing, inlet box, and air inlet. To ensure optimal performance and versatility, the fan is equipped with a damper and other components. The auxiliaries are the powerhouse behind this system, featuring a high-performance motor, a hydraulic coupling for seamless operation, an actuator for precise control, and additional components that work in harmony to deliver unparalleled efficiency.
Our centrifugal fans offer various advanced transmission methods to suit diverse applications: from the motor direct connection (A type), ensuring maximum efficiency, to the belt transmission options (B, C, E type), which provide flexibility and ease of maintenance. For applications requiring high precision, the coupling transmission (D type) offers superior performance, while the coupling transmission with an inlet box (F type) is ideal for demanding environments. The E type and F type stand out with the ability to be designed as double suction fan types, providing enhanced airflow capabilities and unmatched reliability.
Upon arrival of the fan, it is imperative to meticulously examine each component to ensure there is no damage or missing parts. Any defects or discrepancies must be promptly reported to Dart-Rich for resolution.
as soon as possible.
1. For fan parts delivered in bulk, it’s reassuring to know that some matching components have already been expertly pre-assembled and clearly marked by Dart-Rich prior to disassembly,
packaging, and transportation. These parts must be installed on-site carefully and accurately according to the provided markings to ensure optimal performance.
2. Before embarking on the installation process of the whole machine's ventilator upon its arrival at the site, it is crucial to power the transmission part,
and diligently verify that the rotating parts are free from rubbing or jamming issues. It's essential to also check the coaxiality of the coupling between the fan and the motor. Should any problems arise, adjustments and corrections must be made promptly to guarantee smooth operation.

Boasting over 30 series, more than 800 models, and an astonishing 2800+ specifications, our offerings cater to diverse demands. The flow rate capacity spans a remarkable 200~2800000 m³/h, with pressure parameters ranging from 550~30000Pa. The impeller diameter varies between 300 to 5000 mm, while the fan unit's weight ranges from mere tens of kilograms to substantial tens of tons.
Chemical industry: Our fans are expertly designed for the rigorous demands of power stations and serve as induced draft fans for cracking furnaces. They regenerate fans and enhance a multitude of processes such as heating furnaces, reboilers, and incinerators. Our equipment is essential for ethylene cracking furnaces, sulfur recovery, drying, gasifiers, and tail gas treatment. Whether in atmospheric and vacuum distillation, catalytic cracking, hydrocracking, or delayed coking, our fans excel in key operations. They are pivotal in catalytic reforming, ethylene cracking, aromatics production, and propane dehydrogenation. Additionally, they support advanced processes like coal to oil conversion, synthetic ammonia synthesis, and coal to ethylene glycol transformation. Our range includes fans made from special materials, high-sealing and explosion-proof designs, and those specifically crafted for carbon calcination, material delivery, and VOCs treatment systems.
