We can almost provide filter solutions for all light & heavy duty vehicles, no matter it is a small car, commercial vehicle, agriculture vehicle or engineering vehicle. At PLM, our filter combinations can satisfy all harsh requirements of vehicle manufactures, no matter they require a reliable air filter, a high performance oil filter, a durable fuel filter or a protective cabin filter. It is recommended to replace your filter elements regularly to ensure they can always run in perfect conditions.
Recommendations On
Filter Element Replacement Cycle
If you fail to replace your filters regularly, filter may be clogged and lead to
1.Reduced engine power and increased pollution emissions.
2.Higher fuel consumption.
3.Increased debris particles, causing wear and tear on the engine
4.Failures when starts the engine.
Air Filters
Air filter is used to filter the air in the engine to avoid harmful
substance from being sucked in, including dust, soot, smog,
pollen and other pollutants. If these substances enter the
engine, it will increase the abrasion between the piston and
the cylinder and lead to fuel to be mixed into the combustion
chamber, thus increasing the engine fuel consumption
and exhaust emissions, decreasing the engine power and
shortening its service life.
When driving a certain mileage, a large amount of dust and
impurities will accumulate the surface of the air filter, resulting
in a decline in air permeability, therefore, the air filter must be
replaced regularly.
BENEFITS
1. Clean the air that goes into the engine, holding the dust and
abrasive particles in the filter, thereby avoid engine wear and tear
2. High dust separation efficiency.
3. Help maintain regular fuel consumption.
4. Reduce engine noise and optimize performance.
AIR FILTER STRUCTURE
Structure of Filter Paper Air Filters for Light
Vehicles
1. Filter media: plant fiber pleated filter paper
2. Frame: polyurethane sealant molding frame is used
to ensure the best fit and sealing.
3. Optional support mesh type
(1) Expanded metal mesh
(2) Perforated metal mesh
(3) Perforated plastic mesh
4. Optional pre-filtration layer type: In high dusty areas,
air filters are provided with a pre-filtration layer.
(1) Sponge
(2) Non-woven fabric
Structure of Non-Woven Fabric Air Filters for
Light Vehicles
1. Filter media: non-woven fabric Filter media is suitable
for high humidity filtration environments.
2. Solid propylene structure.
3. Sealing polyurethane gasket: good sealing effect.
Eco-Friendly Air Filters
Non-woven fabric material: PP non-woven fabric or PET nonwoven fabric with good air permeability and great filtration
efficiency
Pleating process: pleated manually via the knife on the mold
or pleated by the heat sealing cotton inserter.
After pleating, it is put into the heat sealing mold for heat
forming.
Structure of Single Element Air Filters for Heavy Duty Vehicles
1. End caps:
it consists of a top cap and a bottom cap to combine the filter element together.
(1) Metal end caps: provided with a gasket
(2) PP plastic end cap
(3) Polyurethane (PU) end cover:
high strength polyurethane structure, with better adhesion and sealing.
2. Inner support tube: It plays a role of supporting the Filter media and improving
the stability of the Filter media. There are main three types:
(1) Perforated tubes
(2) Expanded metal mesh
(3) Plastic tube (generally used with PP end caps and PU end caps)
3. Filter media: high filtration efficient, pleated filter paper;
regular folding space creates a higher dirt holding capacity.
4. Optional additional reinforcement layer: Provide additional reinforcement to the
pleated filter paper. There are three main types:
(1) Beading stabilises the media and prevents pleat wear.
(2) Plastisol spiral winding fixation
(3) Filament spiral winding
5. Optional outer support tube: perforated metal mesh or expanded metal mesh
is employed to reinforce and protect the filter media, making its structure more stable forming.
Structure of Dual Element Air Filters for Heavy Duty Vehicles
1. Primary filter: It is used to remove impurities from the airflow entering the
absorption process and plays the most important role in the air filtration. It can
filter particles smaller than the dust collection filter.
(1) Top & bottom caps: metal end caps (with seal gasket) or PU end caps.
(2) Inner support tube
(3) Filter media: pleated filter paper.
(4) Outer support tube: expanded metal mesh
2. Secondary filter: also known as inner filter.
(1) Top & bottom caps: metal end caps (with seal gasket) or PU end caps.
(2) Filter media:
3. Pleated filter paper (typically, inner and outer support tubes are made of
expanded metal mesh)
4. Non-woven felt fabric (generally, inner support tube is made of perforated
metal mesh or plastic tube )
TECHNICAL DATA
Initial air flow resistance: Under the rated air volume flow, the initial air flow resistance of the element
shall not be greater than 2.0 kPa.
