Brand and Model
This fan is produced by the well-known brand ebm-papst, which has a high reputation and rich experience in the field of ventilation equipment. The part number is R4D355-AH11-09, which represents the unique specifications and characteristics of the fan, making it easy for users to accurately identify and choose from numerous products.
Fan Type
It belongs to centrifugal fans. The working principle of a centrifugal fan is to use the centrifugal force generated by the rotation of the impeller to suck in and accelerate the discharge of air. It has the characteristics of large air volume and high pressure, and is suitable for situations that require large ventilation and overcome certain resistance.
rated voltage
The rated voltage is 400V, and this design enables it to adapt to common high-voltage power systems in industrial settings. A stable 400V voltage input can ensure the stable operation of the fan and provide continuous and reliable power for the ventilation system.
Specification
The size of the fan is 355 millimeters, which is relatively compact. This compact appearance gives it a great advantage in environments with limited installation space, whether it is in narrow corners of industrial workshops or in ventilation ducts in commercial buildings, it can be easily installed without taking up too much space.
Maximum air volume and maximum pressure
The maximum air volume can reach 2585m³/h, which means it can transport a large amount of air per unit time to meet the ventilation needs of large areas. The maximum pressure is 300Pa, and higher pressure can enable the fan to overcome certain pipeline resistance and air resistance, and transport air to a longer distance or higher position.
Input power and speed
The input power is 170W, and a lower input power indicates that the fan has good energy-saving performance, which can effectively reduce energy consumption during operation and save costs for users. The speed is 1400rpm, and a stable speed can ensure that the fan can continuously and stably output air volume and pressure.
Efficient impeller design
R4D355-AH11-09 adopts a carefully designed impeller. The blade shape and angle of the impeller have been optimized to effectively suck in and accelerate the discharge of air during high-speed rotation, improving the efficiency of the fan. This design not only increases air volume and pressure, but also reduces energy loss, allowing the fan to achieve better ventilation at the same input power. At the same time, the impeller is made of high-strength and lightweight materials, which reduces the moment of inertia, reduces the load on the motor, and improves the overall reliability and service life of the fan.
High quality shell material
The casing of the fan is made of high-strength metal material, which has good corrosion resistance and mechanical strength. In harsh industrial environments such as humid, dusty, and chemically corrosive places, the casing can effectively protect the key components inside and prevent them from being damaged. In addition, the design of the casing also considers the needs of heat dissipation and noise reduction. By optimizing the structure and surface treatment of the casing, the heat dissipation efficiency is improved and the noise generated during fan operation is reduced.
motor performance
The equipped motor has the characteristics of high efficiency and stability. The motor can operate stably at a rated voltage of 400V, providing reliable power support for the fan. The design of the motor also considers energy-saving and heat dissipation factors. By optimizing the winding and magnetic circuit design of the motor, the efficiency of the motor is improved and energy loss is reduced. At the same time, the cooling system of the motor can timely dissipate the heat generated during operation, ensuring the normal working temperature of the motor and extending its service life.
Industrial ventilation field
In industrial production, R4D355-AH11-09 can be widely used for ventilation and air exchange in various workshops. For example, in a machining workshop, it can promptly discharge metal dust and harmful gases generated during the production process, ensuring air quality and employee health in the workshop. In the chemical workshop, this fan can prevent the accumulation of harmful chemical gases and reduce the risk of explosion and poisoning. Its compact size and efficient performance enable it to be flexibly installed and used in different industrial environments.
Commercial building field
In commercial buildings such as shopping malls, hotels, office buildings, etc., R4D355-AH11-09 can be used as ventilation equipment for air conditioning systems. It can introduce fresh outdoor air into the room, discharge polluted indoor air, achieve air circulation and renewal, improve indoor air quality, and provide a comfortable environment for customers and employees. Its low noise characteristics will not interfere with the quiet environment of commercial places.
Equipment supporting field
For some equipment that requires ventilation and heat dissipation, such as large electrical equipment, server rooms, etc., R4D355-AH11-09 can be used as a matching fan. It can timely remove the heat generated by the equipment, ensure the normal operation of the equipment, and extend the service life of the equipment. At the same time, its stable performance and energy-saving characteristics also meet the requirements of equipment matching.
key points of installation
When installing R4D355-AH11-09 fan, the first thing to ensure is that the installation foundation is firm and flat. The foundation should be able to withstand the vibration and weight generated during the operation of the fan, avoiding abnormal operation of the fan caused by unstable foundation. The inlet and outlet pipelines of the fan should be tightly connected to prevent air leakage. At the same time, attention should be paid to the layout of pipelines, minimizing bends and resistance as much as possible to improve ventilation efficiency. During the installation process, it is necessary to strictly follow the requirements of the installation manual to ensure that the installation position and direction of the fan are correct.
Maintenance points
Regular maintenance of the fan is the key to ensuring its long-term stable operation. The maintenance work includes checking whether there is any looseness or wear in the various components of the fan, especially the connection between the impeller and the motor. Regularly clean the dust and debris inside and outside the fan to prevent them from affecting the performance of the fan. For motors, maintenance should be carried out at regular intervals to check the insulation performance of the motor and the lubrication of the bearings. At the same time, it is necessary to regularly monitor the operating parameters of the fan, such as air volume, pressure, speed, etc., and promptly detect and handle any abnormal situations.
In summary, ebm-papst's R4D355-AH11-09 centrifugal fan has become a reliable choice for ventilation and air exchange in industrial and commercial fields due to its excellent parameter performance, unique design features, and extensive application advantages. Through proper installation and maintenance, it can provide users with efficient and stable ventilation solutions.
