In Abu Dhabi’s harsh desert climate, screw compressors face intense working conditions that test their durability and performance. High temperatures, airborne dust, and persistent humidity accelerate wear and tear, making regular maintenance and overhauling a necessity rather than an option. 

Even premium models — including ATMOS screw compressors — can experience performance issues over time if not serviced properly. In this guide, we’ll explore the most frequent problems seen in screw compressors, how to fix them, and why preventive care is the best strategy for long-term reliability. 

1. Declining Air Output and Efficiency 

When a screw compressor starts producing less air or takes longer to reach the required pressure, operational costs quickly rise. 

Likely Causes: 

• Worn or damaged rotors, bearings, or seals 

• Air leakage in the system 

• Dust or debris restricting airflow 

How to Fix: 

• Carry out scheduled inspections to detect wear early 

• Repair leaks and replace faulty seals immediately 

• Clean internal components to maintain unrestricted airflow 

2. Unusual or Excessive Noise 

A noisy compressor is more than an annoyance — it often signals mechanical trouble that, if ignored, can cause major failures. 

Likely Causes: 

• Loose fittings creating vibration 

• Bearings nearing the end of their life 

• Internal misalignment of parts 

How to Fix: 

• Tighten fasteners during maintenance checks 

• Replace worn bearings and lubricate moving parts 

• Perform regular alignment adjustments for smooth operation 

3. Oil System Contamination 

Oil contamination reduces lubrication efficiency, leading to faster wear and possible component failure. 

Likely Causes: 

• Ineffective or damaged oil filters 

• Moisture in the lubrication system 

• Using incorrect oil for the compressor model 

How to Fix: 

• Use high-grade oil filters and replace them at set intervals 

• Monitor and change oil when contamination is detected 

• Always follow ATMOS screw compressor oil recommendations 

4. Higher Energy Usage 

If your power bills are climbing, your compressor may be consuming more energy due to reduced efficiency. 

Likely Causes: 

• Worn internal parts creating excess friction 

• Clogged air filters restricting intake 

• Incorrect system pressure settings 

How to Fix: 

• Replace worn parts to minimize resistance 

• Clean or replace air filters regularly 

• Adjust pressure controls to match operational needs 

5. Frequent Unplanned Shutdowns 

Regular shutdowns disrupt production and often point to underlying mechanical or electrical problems. 

Likely Causes: 

• Overheating from poor ventilation or heavy load 

• Electrical issues such as faulty wiring 

• Inadequate lubrication causing thermal overload 

How to Fix: 

• Improve airflow around the compressor unit 

• Conduct thorough electrical system inspections 

• Maintain proper oil levels and lubrication schedules 

Preventive Maintenance: The Smart Way to Avoid Breakdowns 

In Abu Dhabi’s climate, preventive maintenance isn’t just good practice — it’s essential for extending the life of your screw compressor. 

Best Practices: 

• Inspect components on a routine basis 

• Keep all moving parts well-lubricated with correct oil 

• Replace air and oil filters before they become clogged 

• Maintain accurate alignment of internal components 

• Record all servicing in detailed maintenance logs
