Centrifugal Blower Commissioning Checklist Audit

A Centrifugal Blower Commissioning Audit is a structured evaluation performed to verify that a centrifugal blower system is installed correctly, operates as designed, and meets safety and performance standards before it enters full service. Here’s a clear and organized breakdown of what such an audit typically includes:

Centrifugal Blower Commissioning Audit Checklist

1. Pre-Commissioning Checks

• Documentation Review

  • Review technical specs, drawings, and manufacturer manuals

  • Confirm model, serial number, and design parameters

• Visual Inspection

  • Check for physical damage, rust, or wear

  • Verify alignment of motor and blower shaft

  • Ensure all fasteners are torqued to spec

• Installation Verification

  • Confirm proper foundation and vibration isolation

  • Check ductwork alignment and connections

  • Ensure electrical wiring is to code and matches the schematics

  • Verify lubrication (oil/grease level and type)

2. Mechanical and Electrical Checks

• Rotation Check

  • Bump motor to verify correct direction of rotation

• Coupling and Belt Tension

  • Inspect and adjust as needed per OEM guidelines

• Motor Insulation and Grounding

  • Perform insulation resistance test (megger test)

  • Confirm proper grounding connections

3. Instrumentation and Controls

• Sensors and Gauges

  • Check pressure, temperature, and vibration sensors

  • Calibrate as necessary

• Control Panel Functionality

  • Verify control logic and safety interlocks

  • Test emergency stop and alarm functions

4. Test Run and Performance Verification

• No-Load Run

  • Start blower without load

  • Monitor for unusual noise, vibration, or overheating

• Full-Load Test

  • Operate at design conditions

  • Record parameters:

    • Airflow (CFM)

    • Static pressure (inches of water gauge)

    • Motor current and voltage

    • Vibration and temperature readings

• Compare actual vs. design values

5. Safety and Compliance Checks

• Check safety guards and enclosures

• Confirm compliance with OSHA, NFPA, and relevant local codes

• Verify emergency shutdown functionality

6. Final Documentation and Handover

• Record all test results and observations

• Note any deficiencies or required corrective actions

• Provide a signed commissioning report

• Deliver O&M manuals and training to operators (if required)
