Restoring Airflow, Pressure, and Performance to Your
Operations
Industrial blowers are the lungs of your facility. Whether they are providing aeration for wastewater treatment, pneumatic conveying for food processing, or dust collection for
manufacturing, a blower failure can halt your entire production line.
At A+ Quality Gearbox Repair, we provide expert diagnostic and restoration services for all
types of industrial blowers and fans. Our in-house machine shop capabilities allow us to restore critical clearances and balance components to ensure your blowers run cool, quiet, and vibration-free.
Specialized Blower Repair Capabilities
We service a wide range of blower technologies, each requiring a specific technical approach:
- Roots & Positive Displacement (PD) Blowers: These are the workhorses of the industry. We specialize in timing gear synchronization, meshing of the lobes (rotors), and bearing/seal replacement for brands like Roots, Sutorbilt, Gardner Denver, and Aerzen.
● Centrifugal Blowers & Fans: Common in HVAC and dust collection. We focus on
impeller repair and dynamic balancing to eliminate the vibration that destroys bearings and housings.
● Regenerative (Vortex) Blowers: Often used in vacuum lifting or aeration. We repair
motor-to-impeller alignments and replace specialized high-speed bearings to prevent catastrophic motor failure.
● Multi-Stage Centrifugal Blowers: Used in heavy-duty aeration and gas boosting. We handle complex multi-stage teardowns, shaft straightening, and precision re-shimming.
Our Precision Blower Restoration Process
Because blowers operate at high speeds and tight tolerances, there is no room for error. Our process ensures every unit returns to service in peak condition:
1. Detailed Inspection: We perform a full teardown and clean the unit to inspect the internal lobes, vanes, or impellers for “rubbing” or heat damage.
2. Lobe & Shaft Machining: We can repair scored shafts or resurface rotor lobes that have been damaged by debris or heat expansion.
3. Precision Timing & Clearancing: For PD blowers, we precisely set the timing gears to ensure the rotors interact without touching, preventing friction and future failure.
4. Dynamic Balancing: We balance all rotating assemblies to reduce vibration, which dramatically extends the life of your bearings and mechanical seals.
5. Seal & Bearing Upgrade: We install high-temperature seals and premium bearings to ensure the unit can withstand the rigors of 24/7 industrial use.
