Forward centrifugal fans
Forward centrifugal fans have a blade exit angle of more than 90°. When working, the impeller rotates at high speed to generate centrifugal force, which throws the air from the center to the edge, and discharges it through the pressurization of the worm casing, and at the same time, negative pressure is formed inside the impeller to continuously absorb the air. Widely used in ventilation and air conditioning, industrial gas transportation, dust removal and equipment supporting and other fields, especially in the high-pressure, small air volume scenarios with outstanding advantages, can meet the needs of multi-industry gas treatment.
Backward centrifugal fans
Backward centrifugal fan in the work, the airflow from the fan axial into the blade space, and then driven by the impeller on the one hand with the impeller rotation; on the other hand in the role of inertia to improve the energy, along the radius of the direction of the impeller to leave the fan, relying on the centrifugal force generated to do the work of the fan is called centrifugal fan.
Axial Fans
Axial fan is a kind of ventilation equipment which conveys gas through axial flow, and its core impeller is composed of hub and twisted blades. When working, the motor drives the impeller to rotate, and the blades push the gas to flow along the axial direction (parallel to the direction of the rotating axis), and the gas flows directly from the inlet end to the outlet end of the fan, and the flow direction is basically unchanged, which is similar to the principle of propeller propulsion.
Duct Fans
Duct fan is a ventilation equipment designed for installation in ducts, which is composed of core components such as motor, impeller and casing. Through the centrifugal force or axial thrust generated by the rotating impeller, the air is sucked in and transported directionally along the pipeline to realize the efficient ventilation, air exchange or air conditioning function in the confined space.
Pump
Pump is a mechanical energy through mechanical energy will fluid energy (kinetic or potential energy) to enhance the mechanical device, the use of impeller rotation, piston reciprocation and other principles to change the pump volume or produce centrifugal force, drive the fluid flow, to achieve the transmission, pressurization or circulation function. According to the working principle can be divided into volumetric pumps (such as piston pumps) and vane pumps (such as centrifugal pumps) and other types.

Silent Cabinet Cooling Fan DF200F2-055-A00 for Adjustable Airflow Requirements
Release time:
2026-10-21
Silent cabinet cooling fan delivers reliable airflow, low-noise operation, and efficient ventilation for equipment cabinets
In electrical cabinets and equipment enclosures, selecting a suitable fan involves balancing airflow, operating noise, and power consumption. Our silent cabinet cooling fan DF200F2-055-A00 is a duct fan designed for applications that require a 200 mm fan diameter and multiple operating options. With a single-phase AC power supply, a rated voltage of 230 V, and three available speed, airflow, and power levels, this model offers flexibility for different ventilation requirements.
Three Operating Levels for Different Airflow Needs
The DF200F2-055-A00 provides three operating speeds: 1800 RPM, 2430 RPM, and 2900 RPM. Its corresponding airflow capacities are 600 m³/h, 820 m³/h, and 970 m³/h, while power consumption is rated at 30.5 W, 68.5 W, and 115 W, respectively.
These operating levels give equipment designers and buyers more options when matching fan performance to cabinet ventilation requirements. Where a lower airflow rate is sufficient, the 1800 RPM setting provides an airflow capacity of 600 m³/h with a power rating of 30.5 W. For applications requiring greater air movement, the 2430 RPM and 2900 RPM levels provide 820 m³/h and 970 m³/h, respectively.
Rather than relying on one fixed operating point, users can evaluate these three sets of performance values when selecting a fan for their equipment. The appropriate choice depends on the ventilation demand and the operating conditions of the intended installation.
Electrical Specifications for Equipment Integration
The DF200F2-055-A00 operates on a single-phase AC supply at 230 V and supports both 50 Hz and 60 Hz frequencies. These electrical specifications provide the basic information required when checking compatibility with the power supply of an intended application.
The fan has three listed current ratings of 0.26 A, 0.54 A, and 0.87 A, corresponding to its three power and speed levels. Its rated power values are 30.5 W, 68.5 W, and 115 W. Reviewing the voltage, frequency, current, and power requirements together helps ensure that the selected operating configuration matches the electrical conditions of the installation.
For equipment manufacturers and industrial buyers, these details are important during product selection and system integration. Checking the available power supply and expected ventilation demand before choosing a fan configuration can help avoid mismatches between the fan and the intended equipment.
A 200 mm Duct Fan for Cabinet Ventilation
As a duct fan with a diameter of 200 mm, the DF200F2-055-A00 is an option for ventilation designs that accommodate this fan size. Its airflow range of 600–970 m³/h allows users to compare the available operating levels against the requirements of their cabinet or equipment enclosure.
When evaluating a cabinet cooling fan, buyers should consider more than the maximum airflow figure alone. The required air movement, available installation space, electrical supply, and acceptable noise level all influence product selection. A fan operating at a higher speed may deliver more airflow, but its power consumption and noise rating also increase.
The three available operating levels make these trade-offs clear. At 1800 RPM, the fan delivers 600 m³/h with a noise rating of 59 dB. At 2430 RPM, airflow increases to 820 m³/h and the noise rating is 66 dB. At 2900 RPM, airflow reaches 970 m³/h, with a noise rating of 70 dB. These figures provide a practical basis for comparing the model's performance across its listed operating points.
Evaluating Noise and Power Consumption
Noise is an important consideration when selecting a silent cabinet cooling fan, particularly when ventilation equipment operates near work areas or other noise-sensitive environments. The DF200F2-055-A00 has listed noise ratings of 59 dB, 66 dB, and 70 dB across its three operating levels.
The model name and search requirements may emphasize quiet operation, but actual selection should take the specified noise ratings into account. Buyers can compare the noise level at each operating point with their project's requirements instead of assessing the fan solely by its maximum airflow.
Power consumption is another factor in this comparison. The 30.5 W, 68.5 W, and 115 W ratings correspond to progressively higher speed and airflow levels. Selecting an appropriate operating point allows equipment designers to evaluate ventilation capacity alongside the associated electrical demand and noise output.

These specifications give buyers a clear starting point for assessing the DF200F2-055-A00 against their ventilation requirements. The listed values should be considered together when comparing operating configurations, rather than treating airflow, power, or noise as isolated selection criteria.
Choosing the Right Fan Configuration
Choosing a suitable fan begins with identifying the airflow required by the equipment and confirming that the installation can accommodate a 200 mm duct fan. Buyers should then compare the available speed levels, electrical ratings, and noise figures to determine which operating point best matches the intended application.
Our DF200F2-055-A00 duct fan provides three defined performance options within one model. With a 230 V single-phase AC supply, 50/60 Hz frequency compatibility, and airflow ratings from 600 to 970 m³/h, it offers clearly specified operating choices for equipment ventilation projects.
For buyers sourcing a silent cabinet cooling fan, reviewing the complete specification set is the most reliable way to establish whether this model fits the requirements of a particular installation. The DF200F2-055-A00 brings together its 200 mm diameter, three speed levels, and corresponding airflow, power, and noise ratings in one product, supporting a more informed selection process for cabinet and equipment ventilation.
