Centrifugal Blower Commissioning Checklist Audit

Centrifugal Blower Commissioning Checklist Audit

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 Checklist Audit using mobile app ()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)
