 
FA-ST can offer advice on ‘How to Control Contamination in the Workplace’ to all customers. We are able to give presentations to groups of Managers and Employees. If you think your Company would benefit from Contamination Control Education please contact us for further details.
What is Contamination
It is anything that does not belong in machine fluid systems e.g. paint flakes, rag fibres, metals, grease, weld spatter, sealing materials, dust water etc. When systems are contaminated, efficiency drops, cycle times increase and component and fluid life is shortened. Eventually contamination can lead to catastrophic failure, unplanned downtime, and costly repairs. Customer demand for increased productivity has produced industry trends toward electro-hydraulics, higher system pressures and tighter internal clearances. As a result of these trends, today's fluid systems will not tolerate dirt and contamination threatens reliability throughout the life of all types of hydraulically operated machinery. |

Contamination of Bulk Oil
When bulk oil is supplied to sites it no longer comes under the strict guidelines that the oil producing companies adhere to within their operations. It may change storage depots a number of times before it reaches the end user. The oil is moved from the oil producers storage tanks to sea, rail and road transport, and at each transfer point contaminants, particularly dust particles and water may enter the pipe work and tanks.
The cost to filter the bulk oil at each of these points would be enormous and the industry feels that it would be unrealistic to undertake such a task.
How many end users of the oil products actually have the bulk oil sampled and tested before putting it into their machines, very few, therefore by installing a filter system on bulk tanks, oil drums etc. to meet the machine ISO Oil cleanliness guidelines would ensure that clean oil is being added every time. |

Hydraulic Fluid Application for KLEENOIL Filtration Units |
|
| The cleanliness of your Hydraulic Fluid is critical to the trouble free and cost effective operation of your system. Hydraulic components are very expensive and need special consideration when selecting and filtering this unit.
ISO 4406 code is a standard that is recognized in the industry. Certain recommended fluid cleanliness quantities are necessary to realize the best performances and cost saving operation of your hydraulic system.
Determine the required standard of filtration you require from the chart below:
