Attached is a ventilator that shuts off after running for 5 minutes. Upon closing the suction, the ventilator continues to operate but no longer blows air. What steps should be taken to address this issue? Regards, Fabián.
This appears to be a basic centrifugal blower. If you block the suction, it will not be able to circulate any air! The suction must remain unobstructed for optimal performance.
When disclosing the suction, the amperage at the motor of a centrifugal blower increases, causing the equipment to shut off. The motor's specifications are IP54 2.15 A 460Y V 1.1 Kw 60 Hz 3420rpm. What steps can I take to address this issue? Thank you, Fabián.
If your motor is not operating with the suction fully open, there may be an issue with the motor. I recommend removing it for inspection. Running the motor with the suction shut is like running it off load. Since it is a three phase 460V Y (star connected) motor, measure the current in each phase while running it. If you are unable to do so, disconnect the motor from the supply to check insulation, each phase to ground, and the resistance of each phase to the star point. Taking these steps will help diagnose any potential problems with the motor.
Thank you so much, Mr. Cheddar-Caveman, for your feedback. I truly appreciate it and will take the necessary steps to make the required corrections. Regards, Fabián.
It sounds like there might be a couple of issues here, Fabián. The automatic shut-off might indicate a problem with the motor or a sensor might be detecting an abnormal condition, such as overheating, and it's trying to protect the system. As for the air not blowing when the suction is closed, that might suggest an airflow issue or a valve problem. You might want to consider getting a professional technician to diagnose the problem, since these types of issues often require physical inspection and electrical testing.

Answer: 1. Why does my ventilator shut off after running for 5 minutes? - The ventilator may be overheating or there could be a problem with the ventilation system itself. It's important to troubleshoot to identify the root cause.
Answer: - This could indicate a blockage or issue with the airflow. Check the ventilation tubing, filters, and connections for any obstructions or leaks.
Answer: - Ensure the ventilator is placed in a well-ventilated area to prevent overheating. Check for any loose connections or faulty components that may be causing the issue.
Answer: - Regularly clean and inspect the ventilator components, replace filters as needed, and follow manufacturer's guidelines for maintenance to prevent unexpected shutdowns.
