Does the air filter combination need to drain excess oil or contaminants from the lubricator?

Yes, the lubricator in the air filter combination usually needs to regularly discharge excess oil or pollutants to ensure the normal operation of the lubrication system and maintain its performance. Draining excess oil or pollutants helps prevent lubricators from overloading or clogging, and keeps the oil clean and in moderation. This is usually achieved through the oil drain valve at the bottom of the lubricator.
The following are the general steps to remove excess oil or pollutants from the lubricator:
Stop lubrication system: Before discharging excess oil or pollutants, stop the lubrication system and close the oil supply valve of the lubricator.
Release pressure: Use the pressure relief valve in the lubrication system to release any remaining pressure in the lubricator.
Drain oil: Open the drain valve at the bottom of the lubricator to drain excess oil or pollutants into a suitable container. The discharge process may take some time, depending on the degree and quantity of oil contamination in the system.
Close the oil drain valve: Once the oil is completely drained, close the oil drain valve and ensure a good seal to prevent leakage.
Check oil level: Check the oil level in the lubricator to ensure that it is within the appropriate range. Add clean lubricating oil if necessary.
Restart the system: Restart the lubrication system and monitor its performance to ensure normal operation.
Regularly draining excess oil or pollutants from the lubricator is a key step in maintaining the stability and performance of the lubrication system. This helps to prevent overload or blockage of the lubricator, reduce the risk of equipment failure, and extend the service life of the lubricator. Based on actual operation, it is recommended to establish an appropriate oil discharge frequency and strictly follow the manufacturer's recommendations for maintenance.
