Though coalescing air filters are very efficient at removing particulate contaminants as small as 0.01 microns from the compressed air stream, their main purpose is to remove oil vapor in order to provide the virtually oil-free air required by some applications by causing the oil vapor droplets to coalesce on the surface of the filter element. To coalesce means to unite to form one mass. Hence, small oil vapor droplets combine to form larger droplets. Typically, general purpose airline filters are located immediately upstream from coalescing filters to increase the lifespan of the coalescing filter element.

Safety Related Notes

Before working on this machine, perform lockout-tagout procedures per the rules of your plant. Determine the sources of energy on this machine – electrical, pneumatic and hydraulic – and release or vent sources of stored energy – electrical capacitors, air receivers, and hydraulic accumulators. Shut off sources of power – electrical, pneumatic and hydraulic. Safely block mechanical sources of energy such as loaded springs and loaded machine members, or safely position the machine members so they are unloaded and springs are not under tension. Beware of hot hydraulic fluid and hot surfaces which can cause burns. Never “crack a hydraulic or pneumatic fitting” to check for the presence of stored energy. Hydraulic fluid injection injuries, as well as injection injuries from many other fluids, are extremely serious and must be treated immediately by medical personnel familiar with this type of injury. Loss of body parts or death may result from improperly treated fluid injection injuries! Never use your hands to feel for a hydraulic leak! Never use compressed air to blow dust off yourself or someone else – there is risk of an air injection injury. Review the schematics and think before proceeding to work on the machine to ensure you have made the machine safe to work on.
