Spin-on Oil Filters
Spin on oil filters are especially fabricated for liquid filtration in
internal combustion engines. This technique is vastly used in various
automobile and mobile heavy equipments. To be applied in several engine
applications, they are available in different combinations of sealing
gaskets and mounting threads.
Fabrication : Spin on oil filters comprise a single unit of housing
and filter element. The entire unit is replaced during maintenance. By using
a threaded fitting, these oil filters can be attached to the side of engine
block. Through out several years, many developments have been made in terms
of filter size, involving length, diameter, sealing gasket diameter and
thread size variation. The designs have also change, some of them uses
internal by pass valve while some uses anti drain back valve. As per the
engine and service requirements, filtration media also vary according to the
model.
Material Used in Spin-on Oil Filters:
Usually, cellulose filter
media is used in disposable spin on oil filters. The top end spin on oil
filters are made up of extremely fine metal mesh or micro glass where as
high performance oil filters are made up of synthetic media. As the oil
passes through the filter media, it captures organic and inorganic
contaminants. The organic contaminants comprise bacteria and other organisms
while inorganic consist dust which is ingested into the engine, along with
trace amounts of wear metals from bearings and other internal components.
Spin-on Oil Filters Applications:
Spin on oil filters are highly
advantageous as they are simple, light weighted and available in varied
range of sizes, styles and capacities. The element is easy to dispose and
removable. Widely applicable in multiple filtration applications like :
- Mobile equipments
- Return line filters
- Lubrication oils
- Hydraulic fluids
- Suction filters
- Fuels in engines, machines and hydraulic systems
