PD Blower & Vacuum Pump 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.
PD Blower Cleaning:
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. 
Machining capabilities:  
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 CNC lathes 
              CNC Vertical and Horizontal End Mills
              Resurfacing machines
              Computerized dynamic balancing machine
              Advanced welding equipment

All PD blowers and vacuum pumps are rebuilt by one of our many factory trained technicians using proprietary tools and methods only available at Blocker & Wallace.

              - Discharge air temperatures
              - Discharge pressures produced at multiple time intervals
              - Units overall operating temperature
              - Bearing  vibration analysis
              - Motor & amp draw
