Filters are an important part of removing contaminants from the air. Different types of air compressors release different kinds of pollutants, including dust, pollen, oil vapors and aerosols. Depending on the air compressor you use, filters are used to meet purity standards in various environments. Here are the types of filters used in compressed air systems.
Vapor Removal Filters
These donaldson compressed air filters remove gaseous lubricants. An adsorption process is used to collect and remove unsafe air particles. This kind of filter shouldn’t be used with lubricant aerosols because the filter will absorb too much too quickly and be useless in a couple of hours.
Particulate Filters
A membrane is used in a particulate filter to remove dust and other particles from the air. The membrane allows air to pass through while capturing the larger objects to keep the air as clean as possible. Air can travel quickly through pipes without forming clogs.
Coalescing Filters
When you need to remove oil and aerosols from the air, a coalescing filter is used. It prevents condensation from building up inside of your air system, which can prevent damage due to rust. Water and oil are the most common particles removed using this type of filter.
Activated Carbon Filters
To remove vapors and odors from the air, activated carbon filters can be used. They are used for areas where food is processed and where clean breathing air is required. The carbon collects the contaminants in the air so that fresh air is sent through the rest of the air system.
When using filters to clean the air in various environments, one of the most important maintenance tasks is to change the filter. Filters only last a specific amount of time and it varies depending on the type of filter you’re using. Follow the instructions and change them as often as required for the highest quality air.
