Introduction

Oil Filters one of the essential prerequisites for the satisfactory operation of an internal-combustion engine is the continuous lubrication of the moving parts of the engine with oils which are kept at the required level of cleanliness to avoid any premature wear.

  1. The oil filter plays an essential part in this process because it provides continuous purification of the oil by retaining abrasive particles, caused by normal wear and tear, as well as dust and combustion residues.
  2. The oil pump, driven by the engine, aspirates the oil via a sieve (to prevent aspiration of large contaminants) from the oil sump and pumps it towards all the places that need lubrication.
  3. Oil filters can be designed as a 'spin-on filter' or as a 'filter cartridge' in housing. A 'spin-on' filter is completely replaced after its useful life, whereas only the filter inside the 'filter cartridge' housing needs to be replaced.
  4. The oil filter is a very advanced and high quality product which helps ensure that the vehicle will operate more efficiently. It consequently plays an essential part in engine performance as well as extending engine service life. This can only be achieved by replacing it at regular intervals, before the filter begins to be bypassed.
Spin-on Oil filters
- Spin-on oil filters consist of a housing and a filter element inside the housing. The filter element is sealed inside the housing and cannot be removed, so the filter must be changed as a whole unit.

- Although most oil filters may appear identical on the outside, they differ on the inside. They may or may not have anti-drain valves, the media may differ, the threads may be different, etc.

- Therefore care must be taken when changing the oil filter. If the wrong filter is installed, engine damage may occur.
B. Plastic Air Filters
- These filters are categorized by having a rigid plastic frame surrounding the media.
They are available for both panel and radial style filters.
They usually have a flexible plastic gasket surrounding the edge of the plastic frame.
They sometimes are divided down the middle of the filter by a divider of rigid plastic.
They are produced in both dry type and wet type. In the dry type, a cotton media is used.
In the wet type, the filter media is composed of paper, which is sprayed with oil.
C. Steel Cap Air Filters
- This filter is made in both the dry and wet types. Some of the filters have a metal mesh lining. They can be radial or square in shape with a hollow center. The top and bottom caps are made out of steel. Some of the radial shaped steel cap filters have a rubber ring on the cap. Various types of media can be used to produce these filters.
