How to choose the best fan for you?
When you need to equip your working environment with the most cost-effective and stable ventilation equipment, what environmental factors do you need to know? The following is our company to provide you with some references. When selecting a fan, the following parameters need to be considered:
1. Air volume: refers to the amount of air that the fan can transmit, usually the unit is cubic meters per hour (m3/h), or CFM, when selecting the fan, it is necessary to determine the required air volume according to different uses and environments.
2. Full pressure: refers to the pressure generated by the fan, usually the unit is PASCAL (Pa), the size of the static pressure directly affects whether the fan can deliver enough air volume. Different uses will correspond to different wind management requirements and pressure requirements, which will directly affect the type of fan required, such as axial flow fans, the general air volume is relatively small, and the pressure is small; There are more types of centrifugal fans, and it can be divided into many kinds according to the pressure size, such as low-pressure centrifugal fans: such as 4-72 series centrifugal fans, 4-73 series centrifugal fans, 4-79 series centrifugal fans; Medium pressure centrifugal fans: such as Y5-51 series centrifugal fans, 6-24, 6-35, 6-42 series centrifugal fans, 7-28 series centrifugal fans; High pressure fans such as :8-09 series centrifugal fans, 9-12 series centrifugal fans, 10-18 series centrifugal fans, 8-39 series centrifugal fans, 9-38 series centrifugal fans and so on.
3 Power: refers to the electrical or mechanical power required by the fan, usually in watts (W), when selecting the fan, it is necessary to balance the power of the fan with the required air volume and static pressure. When choosing a motor, you need to consider a certain safety factor, that is, you need to choose a motor with more power than required.
4. Noise: refers to the noise generated by the fan during operation, usually in decibels (dB), and the relevant noise standards of the environment need to be considered when selecting the fan. In general, we will use the standard distance from the sound source as the benchmark.
1. Centrifugal fan: It is the most common kind of fan, which can be used in air conditioning systems, ventilation systems, industrial equipment, etc.
2. Axial fan: It is a high-speed small fan, suitable for air conditioning systems and industrial equipment.
3. Mixed-flow fan: It is a fan between centrifugal fan and axial fan, which can have the advantages of both to a certain extent.
4. Jet fan: It is a high-speed small fan, suitable for local ventilation and underground garage exhaust system.
5. Dc fan: is a new type of fan, with energy-saving, efficient, quiet and other advantages, suitable for low power, small equipment ventilation and heat dissipation.
1. Environmental conditions: Determine the environmental conditions that require ventilation or exhaust, such as air temperature, humidity, dust content, etc.
2. Fan use: Determine the working use of the fan, including ventilation, exhaust air, heat dissipation, etc.
3. Duct resistance: The length of the duct, elbow, filter, etc. required for ventilation or exhaust air will bring additional resistance to the fan, and the static pressure parameters of the fan need to be selected accordingly.
4. Power supply and control mode: Select suitable power supply and control mode, including AC power supply, DC power supply, electronic speed regulation, automatic switch, etc.
5. Installation position: Select the appropriate installation position, including ground, lifting, wall, etc.
[Conclusion] Fan selection is a very professional and complex process, which requires comprehensive consideration of many factors. In the selection of fans, we need to fully consider the actual environment and use, follow the basic rules of fan selection, in order to ensure the selection of the most suitable fan.
