The 4-72 stainless steel belt-driven centrifugal fan offers outstanding corrosion resistance and durability, thanks to its high-quality stainless steel construction. It is ideal for handling moist, corrosive, or chemically aggressive air streams commonly found in chemical plants, electroplating facilities, food processing areas, and laboratory ventilation systems. The belt-driven design allows for flexible speed adjustment by changing the pulley ratio, enabling precise control of airflow and static pressure to match specific application requirements. Additionally, the fan operates with relatively low noise and vibration levels, and its robust structure ensures long service life and reliable performance even under continuous heavy-duty operation. The movable base with casters (as shown in the image) further enhances convenience for on-site positioning and maintenance.

The 9-19 High Pressure Centrifugal Fan is designed for high-pressure forced ventilation in industries such as metallurgical furnaces, glass, electroplating, ceramics, batteries, and radio. It is also widely used for material conveying in processing industries like grain, feed, and mineral powder, as well as for supporting equipment such as carton machinery and tempered glass devices. The 9-19 series features a forward-curved blade design with a cantilevered impeller mounted directly on the motor shaft. Its compact structure consists of a spiral volute casing, a tapered inlet cone, and a high-strength steel plate welded base frame. The impeller undergoes strict dynamic balancing to ensure smooth operation at high rotational speeds, typically ranging from 1450 to 2900 RPM depending on the model size. This design enables the fan to generate static pressures up to 15,000 Pa while maintaining relatively stable flow characteristics, making it particularly suitable for pneumatic conveying systems and combustion air supply applications where consistent pressure output is critical.

The DBF‑series fan cabinet unit is not fitted with built‑in cooling or heating coils and other air‑conditioning components. During operation, the internal fan draws indoor return air and outdoor fresh air at a preset ratio, where the two airstreams are fully mixed inside the cabinet. The mixed air is then delivered to target conditioned zones to achieve ventilation and air renewal. This unit can also switch to exhaust mode to discharge stale indoor air. An air filter mounted at the return‑air inlet provides primary dust‑filtration, capturing most airborne particulate contaminants and improving supply‑air cleanliness. Featuring compact structure and stable operation, this fan box is widely applied for fresh‑air supply and ventilation systems in shopping malls, office buildings, industrial workshops and other types of buildings.
