Prescribed maintenance
August 18th 2008

As industry continues to tackle significant cost pressures Chris Camsell, the UK service manager at Boge Compressors discusses how regular maintenance can help compressed air users reduce their all up costs.

Regular maintenance is the key to reducing life-time maintenance costs. From the outset, if maintenance cost is a criteria of initial purchase of a compressor then the client must look outside the box! For example, an optimised and energy efficient compressed air system will require the least maintenance.

For existing compressor systems, cutting maintenance costs by reducing maintenance frequency on compressors may seem a plausible solution to reducing short term costs in light of increased energy and business costs. However, beware! Cutting regular prescribed maintenance out will lead to increased costs in the long term.

The integrity and efficiency of a compressor will be jeopardised if a recommended service schedule is not followed, with unnecessary premature wear and tear to parts as well as a reduction in the air quality as possible outcomes.

Poor air quality will lead to increased costs in other areas of the business. As an example, an inefficient compressor being used to power a paint spray system may create inconsistencies and blemishes in a paint job. As a result, additional materials and resource may be required to touch up or re-paint the end product. Moreover, a compressor running inefficiently uses more energy which will increase compressed air related electricity bills.

One of the most common misconceptions we have come across is that regular maintenance doesn’t matter. This derives from the time that the piston compressor was the only way of generating compressed air. The modern screw package is totally different. Properly maintained they are reliable and efficient work-horses.

Without regular maintenance they quickly become unreliable. Initially with petty control issues – intake or solenoid based perhaps. In the unluckiest situation it could cause premature airend failure – at that stage the real cost of poor maintenance is counted!

In order to keep costs to a minimum, when planning a compressor maintenance programme it is recommended that the client considers; how many hours a day the compressor operates, what the prevailing site conditions are, whether a mineral or synthetic lubricant is used and whether the compressor is brand new or a used machine.

Opting for a prescribed maintenance plan for your compressed air system will certainly assist in reducing your business costs in the long term.
