Installing an air filter over a grease-laden air-cooled condenser after it has been cleaned is an important step in maintaining its efficiency and longevity. Grease can accumulate on the condenser coils, obstructing airflow and reducing the overall effectiveness of the refrigeration system. By cleaning the condenser, you remove this accumulation which allows for proper heat exchange.

Following the cleaning, adding an air filter helps prevent future build-up of grease and debris. The filter acts as a barrier, capturing particulates in the air before they have a chance to settle on the condenser itself. This proactive measure not only ensures that the condenser remains clean but also enhances the overall performance and energy efficiency of the system by maintaining optimal airflow and cooling capacity.

This approach is considered best practice, as it not only addresses the immediate issue of grease accumulation but also helps prevent future occurrences. Regular maintenance, including the use of filters, is crucial in commercial settings where equipment is subject to heavy use and environmental factors that can lead to contamination.
