air moving technician Interview Questions and Answers

1. What is your experience with different types of air moving equipment?

   • Answer: I have extensive experience with centrifugal fans, axial fans, vane axial fans, and blowers, encompassing various sizes and applications. I'm familiar with their operational principles, maintenance requirements, and troubleshooting techniques for each type.

2. Describe your experience with troubleshooting air moving systems.

   • Answer: My troubleshooting approach is systematic. I start by visually inspecting the system for obvious issues like leaks, debris, or damaged components. Then, I check pressure readings, airflow rates, and motor performance using appropriate tools. I'm proficient in identifying problems related to belts, bearings, motors, and control systems, and I can effectively diagnose and rectify issues such as vibration, noise, and reduced airflow.

3. How familiar are you with safety regulations and procedures related to air moving equipment?

   • Answer: I am very familiar with OSHA and industry-specific safety regulations. I understand the importance of lockout/tagout procedures, personal protective equipment (PPE) usage, and safe handling practices for high-voltage equipment and moving parts. I always prioritize safety in my work.

4. Explain your understanding of airflow dynamics.

   • Answer: I understand the principles of Bernoulli's equation, pressure drop, and frictional losses in ductwork. I can calculate airflow rates, static pressure, and total pressure using appropriate formulas and tools. I also understand the impact of duct design, fan selection, and system balancing on overall efficiency.

5. How do you handle emergency situations involving air moving equipment?

   • Answer: In emergencies, my first priority is safety. I immediately shut down the equipment if necessary, assess the situation, and determine the extent of the problem. I then follow established emergency procedures, contacting supervisors and relevant personnel as needed. I prioritize repairs to restore functionality while ensuring safety.

6. What experience do you have with preventative maintenance on air moving systems?

   • Answer: I have a strong background in preventative maintenance, including regular inspections, lubrication, cleaning, and belt adjustments. I understand the importance of maintaining accurate records and following scheduled maintenance plans to maximize equipment lifespan and efficiency. I can identify potential problems before they become major issues.

7. Are you familiar with different types of motors used in air moving equipment?

   • Answer: Yes, I'm familiar with AC and DC motors, including single-phase and three-phase motors. I understand their characteristics, starting methods, and troubleshooting techniques. I also have experience working with variable frequency drives (VFDs) for speed control and energy efficiency.

8. How do you ensure the proper balancing of an air moving system?

   • Answer: I use pressure gauges and airflow measurement tools to balance the system. I adjust dampers and valves to ensure proper airflow distribution throughout the system, optimizing performance and preventing uneven pressure or airflow.

9. Describe your experience with different types of ductwork.

   • Answer: I'm experienced with various duct materials, including galvanized steel, aluminum, and flexible ductwork. I understand the implications of different duct designs on pressure drop and airflow. I can also perform ductwork repairs and installations.
