One of the essential prerequisites for the satisfactory operation of an internal-combustion engine is continuous lubrication of the moving parts of the engine with oils which are kept at the required level of cleanness to avoid any premature wear. The oil filter has an essential part to play in this process, because it provides continuous purification of the oil, by retaining abrasive particles which are caused by normal wear and tear, and also dust and combustion residues. It has to be capable of withstanding the mechanical and thermal loads created in the environment of the engine. It has to retain the oil when the engine is switched off and it helps to cool the oil to its optimum operating temperature.

Chevron pleating enables:

- an increase in performance whilst retaining the same filter size

- a reduction in filter size whilst retaining the same performance. Purflux manufactures more and more compact and lighter weight filters, using less metallic parts and contributing to:

- a reduction in the level of collection and recycling of used products.

- smaller engine compartment size

- greater ease of fitting

- better environmental protection

The oil filter is a very technological and high quality product which ensures a high efficiency of vehicle operation. It consequently plays an essential part in the maintenance of the engine performance and in extending engine service life. This can only be achieved by replacing it at regular intervals, before the accumulation of retained particles lead to a pressure drop which would reduce its performance to a level where the filter is being bypassed.

It is important to adhere to the vehicle manufacturer’s recommendation, normally to replace the filter at every oil change.

Purflux recommends replacement of the oil filter at least once per year.
