The Essential Guide to Rotary Screw Air Compressor Maintenance

Rotary screw air compressors are the main power plants in the industrial world, as they are the most used source of compressed air for different applications. For the sake of type-high performance and durability of the machine, it is important to do regular monitoring. In this guide, we will be discussing the main aspects of rotary screw air compressor maintenance which will result in the improvement of the working condition of this equipment.

Regular Inspection: One of the most imperative tasks is conducting regular inspections frequently to highlight any problems in the preliminary stages. Ensure the proper routine tasks are done while you still monitor the system for leaks, abnormal sound or vibrations.  Always check the air filter, oil levels, and belts on a regular basis, according to the manufacturer's instructions.

Air Filter Maintenance: Clean or replace the air filters according to the service schedules given by the manufacturer. Filters become clogged and restrict airflow which may lead to inefficiency and damage to internal parts. Your potential audience includes people from all age groups, genders, and professions. Proper filter servicing ensures the best air quality and compressor performance.

Oil Changes: The functioning of Rotary screw compressors is based on the lubricating oil, through which the operation is smooth. Keep a close watch on the oil levels and quality at all times, and make sure that the oil is changed in accordance with the given schedule. The polluted or worn-out oil can lead to the overheating and the early wear which in turn, reduce the efficiency and the reliability of the compressor.

Cooling System Maintenance: The effective cooling is very important to the absence of overheating and the performance of the compressor. Check the cooling fans, radiators, and heat exchangers for dirt and damage, then decide how well they need to be cleaned. Routine cleaning of the cooling system components and the provision of smooth airflow should be the two aspects for the prevention of the thermal problems.

Belt and Drive System Inspection: The drive belts are the ones which pass on the power from the motor to the air end of the compressor. Look at the belts for any signs of damage, check if their tension and alignment are okay, and change them if they are not. Compressed belts that are misaligned or worn can cause the compressor system to work less efficiently and the parts to fail earlier.

Monitor Operating Parameters: Monitor the main operating parameters like the discharge pressure, temperature, and power usage. Irregularities are found in these parameters which can be the indication of the problem which needs to be solved. Routine monitoring allows the detection of possible troubles at an early stage and thus preventing the occurrence of problems.

Professional Servicing: The qualified technicians should be employed for the purpose of periodic servicing as well as the inspections which are complete. Professionals who have been in the field for a considerable period of time can detect the elusive problems, make the delicate adjustments, and follow the instructions given by the manufacturer. Professional servicing boosts the compressor reliability and thus, it becomes less of a problem to have no compressor working.


Rotary screw air compressors are very important in the industry, and their maintenance should be done properly for the purpose of achieving high efficiency and long-life span. Through the proactive maintenance of the system that includes the inspections, filter and oil maintenance, cooling system checks, and the professional servicing, you can make sure the performance and the reliability of the rotary screw compressor are at their best levels.
