How Often Compressed Air Equipment Should be Serviced
Have you ever wondered why suddenly, for no apparent reason, your compressed air system has been down? Now think – have you been performing regular service on your air compressor? Servicing your equipment is crucial because it helps you prevent downtime and ultimately, decreased productivity, too.
Preventive maintenance is necessary. It is also much simpler and more inexpensive compared to what downtime and repairs would cost you if you overlook your system’s maintenance. So, how often should you really service your air compressor, dryer, and oil/water separator? What should be included in the service?
FOR ROTARY SCREW LUBRICANT AIR COMPRESSOR, ROTARY VANE AIR COMPRESSOR, and ROTARY SCREW FOOD GRADE
A basic preventive maintenance should be performed every 1000 to 2000 hours and should include changing air filters, oil filters, and panel filters if applicable. All electrical connections should be tightened and the running condition of the equipment should be recorded.
A full preventive maintenance on the other hand, should be done every 4000 hours or once a year. Tit should include changing air filters, oil filters, panel filters, and lubricant. Drain valves and belts should be checked. Running condition should be recorded and electrical connections tightened.
FOR OIL/WATER SEPARATOR
Basic checks should be done every 1000 to 2000 hours or every three to six months. They should include ensuring proper drainage of the condensate drains to the water or oil separator unit, checking water level and seeing if there’s excessive oil build-up within the water or oil separator unit, and of course, performing a basic cleaning.
A full preventive maintenance would be performed every 9000 hours or approximately 1-2 years. It would include all the services that come with basic maintenance plus changing absorption and carbon elements and performing a thorough cleaning to make sure no residual or bulk oil is left in the unit.
FOR DESICCANT AIR DRYERS
A basic preventive maintenance would include monitoring dew point, checking switching valve, and inspecting muffler and desiccant. This would be done every three to six months of operation.
A full maintenance, done every two to five years, depending on the usage and the air quality, includes monitoring dew point, changing mufflers, checking switch valves, replacing desiccant media, and pre-& post line filtration elements.
FOR REFRIGERATED AIR DRYERS
Completed every 1000 to 2000 hours, a basic preventive maintenance includes testing drain valves and cleaning strainers, blowing out condenser coils, and checking suction pressure.
A full service is done every 4000 hours or annually. It includes all the services included in the basic maintenance plus the replacement of related pre-and post line filtration elements.
