Blocker & Wallace Blower Repair Process:
Tear Down & Blower Evaluation:
Blower tear down and evaluations are performed by factory trained technicians with no charge to the customer.
Detailed Repair Quote:
We provide a formal detailed quote including a cause of failure and proof of  damaged sustained with description and photos of damaged parts. We are able to estimate the unit's performance if rebuilt and provide recommendations on system changes that can prevent future failures.
Upon repair quote approval, the entire unit will be thoroughly cleaned of all foreign contaminants in our separate cleaning facility by way of sandblasting, polishing, & provide rust prevention coatings in critical areas after the cleaning process is completed.
Dynamically Balanced Rotors:
All rotors are dynamically balanced on our computerized dynamic balancing machine to insure proper performance. Most rebuild centers don't have the sophisticated equipment needed to check for rotor balance which is necessary to insure prolonged blower life & bearing life.
With our own in-house machine shop we can insure quality & quick turnaround time on machines that may be required during the rebuild process.
Machine Shop Equipment:
Multiple lathes that are CNC controlled
CNC End Mills
Computerized dynamic balancing machine
Advanced welding equipment
Rebuild / Assembly Process:
All Units are rebuilt by one of our many factory trained technicians using proprietary tools and methods only available at Blocker & Wallace.
All units undergo rigorous testing in our state of the  art testing station. Blowers are tested for  at least one hour under simulated load at their maximum operating limitations to insure proper operation and performance.
Testing Includes evaluation and recording of:
- Discharge air temperatures
- Discharge pressures produced at multiple time intervals
- Units overall operating temperature
- Bearing  vibration analysis
- Motor & amp draw
- Visual inspections of all seals and critical components
Final Unit preparation for shipment:
All units will be prepped with all necessary decals, serial number tags & painted industrial metallic grey. Units will be adequately palletized & protected for safe shipment.
