Daily Inspections for Screw Air Compressors

Daily inspections help you maintain the reliability and efficiency of screw air compressors. You can prevent unexpected failures and costly downtime by following a standardised routine. Early detection and prompt reporting of abnormalities are essential for safe and economical operation.

Monitoring operating parameters

You should monitor key operating parameters every day. Recording these values hourly allows you to spot trends and identify issues before they become serious. The table below shows the most important parameters to check:

Key Operating Parameter	Description
Oil Level	Ensure the oil level in the oil-gas separator is above the minimum mark.
Discharge Pressure	Monitor the pressure at which the air is discharged from the compressor.
Discharge Temperature	Check the temperature of the air being discharged to prevent overheating.
Voltage	Record the voltage supplied to the compressor for stability checks.
Current	Monitor the current draw to ensure it is within normal operating limits.
Abnormalities	Stop the compressor if there are abnormal vibrations, noises, or oil leaks.

Tip: You should always stop the machine if you notice abnormal vibrations, noises, or oil leaks. Early action prevents further damage and keeps your equipment safe.

Equipment condition checks

You need to inspect the physical condition of screw air compressors regularly. These checks help you find leaks, wear, and other problems before they affect performance. Leading manufacturers recommend the following inspection routines:

• Drain the drip tray daily to prevent moisture buildup.

• Monitor the compressor’s temperature to avoid overheating.

• Check for rust and signs of corrosion.

• Ensure adequate lubrication to reduce friction and heat.

• Monitor for excessive pressure and adjust as necessary.

• Inspect for leaks (air, moisture, and oil).

• Verify proper operation of controls and indicators.

• Check the air filter for blockages.

• Observe for unusual noise or vibration.

• Examine safety relief valves for signs of activation or tampering.

• Inspect hoses and connections for wear or damage.

• Review operating pressure levels.

• Check condensate traps.

• Look for noticeable signs of damage.

You should perform these checks daily, weekly, and monthly, as shown in the table below:

Maintenance Type	Frequency
Daily	Inspect for air/oil leaks, top off oil, drain condensate, check noise/vibration.
Weekly	Clean/change inlet filters, test controls.
Monthly	Clean heat exchangers; check belts and hoses.
Basic PM	1,000–2,000 hrs/6 months: Change filters, log conditions, tighten connections.
Full PM	2,000–4,000 hrs/12 months: Add oil separators, replace belts and drain valves.

Maintenance for Industrial Air Compressor

Proper maintenance is the foundation of reliable industrial air compressor operation. You can achieve high efficiency, reduce downtime, and extend equipment life by following a structured compressor maintenance schedule. This section explains the essential routines and intervals for rotary screw compressor care, helping you meet technical specifications and general rules and specifications in your facility.

Daily and weekly routines

You should perform daily maintenance and weekly checks to keep your industrial air compressor in optimal condition. These routines help you detect issues early and maintain efficiency. The following table summarises the most important daily and weekly tasks:

Interval	Tasks
Daily	Inspect for air/oil leaks, top off oil, drain condensate, check noise/vibration.
Daily	Check oil level, inspect for unusual noises or vibration, drain water from air receiver tank.
Daily	Check oil, drain condensate, inspect gauges.
Weekly	Clean/change inlet filters, test controls.
Weekly	Clean air filter; replace if necessary, wipe down air compressor system exterior.
Weekly	Inspect filters, belts, couplings, safety valves.

You should always check the oil level and drain condensate from the air receiver tank every day. Listen for unusual noises and vibrations. These signs often indicate problems that affect efficiency. Each week, clean or replace the air filter and inspect belts, couplings, and safety valves. Wipe down the compressor exterior to prevent dust buildup. These steps form the backbone of routine maintenance and support long-term reliability.

Tip: Consistent daily and weekly routines help you avoid unexpected breakdowns and keep your rotary screw compressor running at peak efficiency.

Monthly and annual servicing

Monthly and annual servicing ensures your industrial air compressor meets technical specifications and maintains high efficiency. You should follow a strict compressor maintenance schedule based on operating conditions and maintenance cycles. The table below outlines standard intervals for servicing:

Compressor Type	Recommended Service Interval
Oil-flooded rotary screw	Every 2,000 to 4,000 operating hours or at least annually
Reciprocating	Every 1,000 hours or every six months

Most industrial air compressor systems require servicing at least once a year. If you use your compressors more frequently, you may need to service them quarterly or even monthly. During monthly checks, inspect the quality of lubricating oil and replace it if it appears dark or contaminated. Test the sensitivity of safety valves and pressure switches. Clean the coolers to improve heat dissipation. Annually, you should perform a comprehensive inspection of the main engine, check rotor clearance, and calibrate all measuring instruments.

You must also focus on the regular replacement of consumables. The following table shows recommended intervals for key components:

Consumable	Replacement Interval
Oil Level	Daily
Oil	Every 4,000 to 8,000 hours or annually
Oil Filter	Every 2,000 hours
Air Filter	Every 2,000 hours
Separator	Every 4,000 hours
Scavenge Line	Every service

8. Implement measures to avoid harmful bacteria growth in water-cooled compressors.

Note: Wearing personal protective equipment, such as gloves and safety glasses, is a must when working with compressors.

Shutdown and emergency procedures

You need to follow a clear process when shutting down the compressor or responding to emergencies:

1. For normal shutdown, close the air inlet valve and let the compressor run without load for several minutes.

2. Switch off the power supply once the temperature drops below 60°C.

3. In an emergency, press the emergency stop button immediately if you notice:

   • Excessive current or pressure readings

   • Interrupted cooling water supply (for water-cooled units)

   • High oil or water temperature

   • Abnormal noises or strong vibrations

   • Severe gas leaks or burning smells

4. After shutdown, release any remaining gas to reduce pressure to zero.

5. Drain condensed water from the relevant components.

6. Record the time, type, and cause of any emergency shutdown for future maintenance.

Callout: Quick action during emergencies protects both your equipment and your team. Always document incidents to support future improvements in safety and efficiency.
