Measures to Address Noise Issues with Low-Noise Duct Fans
To further enhance the performance of low-noise duct fan systems, which is of great benefit to production operations, this is a matter of significant concern for all users.
In fact, there are several methods we can employ to achieve this objective.
Below, we hope to assist you by sharing some key points.
Firstly, many users may lack sufficient knowledge and are unaware that low-noise duct fans can actually be started at full pressure or reduced pressure.
However, when starting the equipment at full voltage, it is necessary to ensure that the circuit capacity is sufficient.
This is because, when starting at full voltage, the equipment’s current is 5 to 7 times the rated current. Therefore, if the circuit capacity is insufficient, a step-down procedure must be carried out to prevent equipment failure.
Secondly, when commissioning a newly arrived low-noise duct fan, it is essential to verify its operation in accordance with specific instructions, paying particular attention to whether the electrical circuit is functioning correctly.
Failure to do so may result in a series of problems should there be an issue with the circuit.
Note: When commissioning the unit, at least two personnel must be present on site. One person should control the power supply, whilst the other monitors the unit’s operational status.
Note: If any faults are detected, the low-noise duct fan must be switched off immediately. The machine should then be inspected and repaired.
After repairs, please wait five minutes before attempting to restart the unit. Even if the machine is operating normally, it is necessary to measure the input current to ensure it falls within the normal range.
If the current exceeds the specified range, the equipment must be shut down for inspection and maintenance.
Adhering to the above guidelines will not only enhance the performance of the low-noise duct fan but also help to extend the machine’s service life.
We hope you will refer to the above conditions and use the centrifugal fan appropriately.
