Six Sigma and The Compressor Room

Throughout my undergrad courses as well as during my professional career I have encountered Six Sigma or Lean Manufacturing in many facilities.  There is at least one component to the theory that can be implemented into any facility with a compressor room. That component is the practice of the 5 S’s.

The 5 S’s of Lean Manufacturing come from the Japanese terms  listed below with their English translations:

Seiri – Sort (Organize)
Seiton – Set in Order (Orderliness)
Seiso – Shine (Cleanliness)
Seiketsu – 
Standardize
Shitsuke –  Sustain (Discipline)

These 5 points can aid in keeping any air compressor room in a facility efficient, safe, and effectively supplying the company with compressed air. How you may ask.

Sort – Keeping a compressor room as originally laid out and preventing it from being a catch-all for items that have nothing to do with the compressed air system. This can easily happen when it is actually a room that has unused floor space in a small facility. By keeping the area clean and free of unrelated materials, maintenance and troubleshooting can be done quickly. Clear labeling of anything kept in the room is also ideal to make items easily identified.

Set in Order – To deliver the air in a single path/direction as well as keeping equipment in locations where they can be easy to maintain and clearly labeled eases the troubleshooting and understanding of how the system is laid out. Rather than having a spaghetti bowl of piping running all around the room to different components it is wiser to keep a flow that matches the process. From the compressor(s) to the receivers, dryers, filter, and regulators, out to the point of use. This shouldn’t be a tangled web of piping that introduces air to a process which bypasses key components such as the dryer or receivers.

Shine – The compressor room shouldn’t be a dirty grungy area. The compressor pulls the air in from this environment. Any exposed components easily collect airborne debris. By keeping the equipment clean again makes labels easy to read and a clean machine is always easier to perform maintenance and sometimes even troubleshoot. If there are puddles of oil or other liquids on the floor and no surfaces are clean then any leak may not be easily spotted.

Standardize – The layout and processes used within the room should be repeatable. Maintenance tasks should be performed on a schedule, per a process that doesn’t allow for much differentiation on methods and end results. This mitigates errors and is always the desired result when focusing on lean manufacturing. LOWER THAT DELTA!

Sustain – This is sometimes the hardest part of any process. Getting the program up and running, starting with a fresh build is always the easiest.  Everything is fresh, new and you want to keep it shiny. Years later the desire to dust and maintain piping as well as keep receiver tanks and floors clean isn’t always at the top of the desired list.  It should always be a priority because cleanliness also promotes safety and reduces overhead by lowering downturns due to housekeeping related failures.
