Fan decks are crucial components in many cooling, ventilation, and heating systems, particularly in commercial and industrial environments such as cooling towers, HVAC units, and air-handling systems. Over time, these assemblies experience wear, fatigue, or environmental damage that can compromise performance, increase energy use, or even halt operations entirely.
With over 30 years of experience, BCB Sales & Service provide specialised fan deck maintenance, cooling tower deck repair, and industrial fan deck service across Australia. Whether you operate a belt-drive or direct-drive system, we can restore your equipment to peak performance — quickly, reliably, and cost-effectively.
Why Is Fan Deck Maintenance So Important?
The fan deck is the platform or structure that supports the fan assembly, including the motor, shaft, housing, and blade system.
When damaged or misaligned, even slightly, it can:
- Disrupt airflow and cooling efficiency
- Accelerate wear on the motor and bearings
- Causes excessive vibration and noise
- Increase energy consumption
- Lead to total fan failure if left unchecked
Routine fan deck maintenance helps prevent costly breakdowns, protects surrounding equipment, and ensures your facility meets ventilation or cooling performance standards.
Our Fan Deck Repair Services Include:
- Structural repairs and weld restoration
- Motor and shaft realignment
- Blade and impeller balancing
- Mount and bracket repair or replacement
- Motor replacement or reconditioning
- Replacement of seals, bearings, or housings
- Full deck component replacement
- Debris and corrosion removal
We understand the urgency when fan deck issues arise. That’s why we offer responsive service, transparent quotes, and fast turnarounds for businesses across Australia.
Fan Deck Types We Service
Our team is highly experienced in both belt-driven and direct-driven fan deck assemblies. Each configuration requires specific knowledge and tools, and that’s where our specialist skills make the difference.
Belt Drive Fan Deck Repair
Belt drive fan decks are commonly used in cooling towers and large ventilation systems. They use a motor that connects to the fan shaft via pulleys and belts, offering flexibility in fan speed and placement. However, they also involve more components that can wear over time.
Common problems we repair include:
- Belt wear, cracking or breakage
- Pulley misalignment or warping
- Loose or damaged mounts
- Shaft and bearing wear
- Excessive vibration or noise
We offer full inspection and repair of belt tensioners, motor mounts, pulley alignment, and fan blades. If your unit is rattling, vibrating, or losing efficiency, we can quickly diagnose the issue and offer a practical fix.
We also stock a wide range of belts and pulleys for fast replacements without long delays.
Direct Drive Fan Deck Repair
In direct drive fan decks, the motor connects directly to the fan hub or shaft. These units are more compact, require less maintenance, and are common in HVAC systems and compact cooling towers. But when problems do arise, they often involve motor faults or blade imbalance.
Our direct drive services include:
- Motor rewinding or replacement
- Capacitor and terminal repair
- Impeller and hub rebalancing
- Bearing and shaft repairs
- Housing and mount restoration
- Electrical diagnosis and servicing
Direct drive fan deck units can be very efficient (when operating correctly). Our repairs ensure minimal downtime and a long service life, utilising only high-quality parts and skilled craftsmanship.

Our Fan Deck Maintenance & Repair Process
We take a thorough and methodical approach to each repair:
-
Initial Inspection: We visually assess your fan deck for wear, corrosion, alignment, and structural damage. If needed, we dismantle the unit for internal inspection.
-
Diagnosis: We test motors, belts, shafts, and fans for vibration, airflow output, and electrical performance to pinpoint the issue.
-
Repair Quote: You’ll receive a clear explanation of the fault and an upfront quote — with no hidden costs.
-
Component Repair or Replacement: Whether it’s repairing a weld, replacing a blade, or installing a new motor, we do the job properly using quality parts.
-
Performance Testing: Once the deck is reassembled, we conduct test runs to confirm alignment, airflow, electrical safety, and smooth operation.
-
Preventive Advice: We’ll also recommend a tailored fan deck maintenance schedule based on your usage, environment, and equipment type to avoid future faults.
