Summary of Selection Guidelines for 304 Stainless Steel Fans

As a user, pay attention to these critical control parameters during the purchase process of 304 stainless steel fans: airflow, total pressure, efficiency, sound pressure level, rotational speed, motor power, etc. Currently, 304 stainless steel fan equipment on the market primarily falls into three pressure categories: - High pressure: p > 3000 Pa - Medium pressure: 1000 ≤ p ≤ 3000 Pa - Low pressure: p < 1000 Pa Therefore, during selection, different types of centrifugal fans should be chosen based on the properties of the conveyed medium and actual application requirements. Additionally, account must be taken of 304 stainless steel fan losses and calculation errors, as well as the actual airflow and negative pressure deviation of the equipment. The airflow safety factor ranges from 1.05 to 1.1, while the fan pressure safety factor is between 1.10 and 1.15. Note that to ensure optimal operation of the 304 stainless steel fan equipment, selecting excessively high values is not recommended. Pay attention to the matching relationship between pipeline network characteristics and fan performance. Simply put, to maintain stable operation of the 304 stainless steel fan equipment, it is best to operate it near its peak efficiency point. Therefore, during selection, prioritize the requirement for operating efficiency, which should not fall below 90% of the fan's peak efficiency. Currently, many users prefer variable-frequency 304 stainless steel fans. When selecting this type, the total pressure loss calculated for the system should be used as the rated air pressure, but the fan motor power should be increased by 15-20% of the calculated value. It is important to note that if the actual operating conditions of the 304 stainless steel fan equipment—such as gas temperature or atmospheric pressure—differ from the sample conditions, the fan performance must be adjusted accordingly.
