Steps to Prepare Your Compressed Air Systems for Hot Weather Conditions

Steps for Preparing your Compressed Air Systems for hot weather conditions

The climate in most parts of the Philippines is hot and humid year-round. The heat tends to get more intense during the dry season. During these months, it is not just your body that experiences exhaustion. Usually, air compressors operate for over 200 degrees. It also generates a huge amount of heat which may affect its operations without proper maintenance.

In order to prevent problems with your equipment and ensure that it will be in excellent running condition, here’s an air compressor maintenance guide to help you prepare for challenging operating conditions.

Compressed Air Maintenance Guide for Summer

Keep Air Compressor Clean

1. Keep the air or oil cooler free from dirt. Ensure the cleanliness of your compressed air system’s coolers in order to improve its performance. In smoky or oily facilities, it would be best to detach the cooler from the air compressor and wash it to get rid of the contaminants.

2. Change the oil. One way to prevent overheating is by changing the oil of your equipment based on quality standards. Ensure that the oil in the machine hasn’t exceeded its expected lifespan to be able to operate without overheating or affecting the components of your system. 

Here’s a brief overview of the life span of oils used in air compressors:

  • Food grade – 1,000 hours
  • Premium synthetic oils – 9,000 hours
  • High-quality non-food grade oil – 8,000 to 16,000 hours 
  • Regardless of the hours, the maximum time that oil should be left in a machine is 2 years.


Always change your oil filter when you change your oil. You also have to beware of low oil levels as this is a common cause of overheating.

3. Keep the motor dirt-free. Dirt may serve as an added layer of insulation that can cause machines to run hot. This can affect the life span of the system’s motor and affect its overload relay too. For air compressors with an open drip-proof type motor, you should blow loose to keep the dirt out of the motor.

4. Address system leaks. Leaks usually come in two forms: oil and air leaks. It is important to detect leaks as they affect proper operations and pose hazards in a facility. In addition to that, leaks are also common causes of unnecessary expenses as a result of energy waste.

Air instrumentation tools like an ultrasonic leak detector is a convenient and reliable way to detect leaks. You can use this tool as a regular part of compressed air system maintenance or complete the audit of your system. Check out Compresstech’s leak detector from SUTO by checking our products. 

5. Check maintenance items. There are important parts of your compressed air system that also needs to be checked as they may contribute to system overheating when not properly maintained.

  • Electrical connections must be inspected as a loose connection can add up to the heat of your equipment too.
  • The oil bypass valve must also be changed regularly as it can stick and cause overheating.
  • Belts and drive coupling must also be inspected for signs of deterioration as they tend to weaken in higher temperatures.

Simple steps like cleaning the entire equipment in and out should help you detect issues easily while ensuring that it can operate properly under hot weather conditions. However, there are also specific maintenance tasks that you should not overlook. With proper air compressor maintenance, you can prevent unnecessary delays in your operations even under hot weather conditions.
