Overview of Oil Filter

An oil filter is a filter designed to remove contaminants from engine oil, transmission oil, lubricating oil, or hydraulic oil. Their chief use is in internal-combustion engines for motor vehicles, powered aircraft, railway locomotives, ships and boats, and static engines such as generators and pumps.

Advantages of Oil Filter

Good filtration effect

The oil filter uses high-quality filter paper to filter impurities and fine particles in the engine, thereby ensuring the normal operation of the engine.

Strong pressure resistance

The oil filter can ensure that it can still work normally when the engine oil pressure changes.

Long Lifespan

Our oil filters are of high quality and don't have to be replaced frequently.

Types of Oil Filter

01/

Primary Oil Filters
The first of the two most common types of oil filters is the primary oil filter, which is also known as the full-flow oil filter. These oil filters are responsible for filtering the majority of the contaminants in the oil.

02/

Cartridge Oil Filter
Cartridge oil filters are one of the simplest and most common oil filters available. The filters are often made of metal or fiber. Their unique mounting position makes them easy to drain and clean whenever you have a stuck oil filter.

03/

Spin-On Oil Filter
On the other hand, spin-on oil filters are comprised of steel canisters with paper elements designed to catch contaminants. Because of the inexpensive paper materials, you’ll find it much easier to repair or change your oil filter.

04/

Secondary Oil Filters
The second of the two most common types of oil filters is the secondary oil filter, which is also known as the bypass oil filter. Secondary oil filters clean up any contaminants the primary oil filters failed to catch. These filters specialize in catching finer debris.

Filter Media of Oil Filter

Cellulose - Comprised of wood pulp with large fibers and an inconsistent pore size.

Fiberglass (Synthetic) - Comprised of smaller, man-made glass fibers with a more consistent pore size.

Composite - Comprised of a combination of cellulose and fiberglass material.

Cellulose media are advantageous because they can absorb some water contamination. However, these types of media tend to fail more rapidly than synthetic media in acidic and harsh oil conditions.

Components of Oil Filter

Permanent canister: Bolted onto the engine block.

Replaceable filter element: Similar to the filter media in spin-on oil filters, this traps contaminants. Only the replaceable filter element inside the canister needs to be changed, while the canister itself remains on the engine.

Bypass valve: Located within the canister housing, it functions similarly to the relief valve in spin-on filters, keeping the oil flowing when the filter is clogged.

Use of Oil Filter

Oil enters the filter

Dirty oil from the engine is pumped into the filter through the inlet port.

Contaminants trapped

The filter media captures dirt, debris, and other harmful particles.

Clean oil exits

Clean oil passes through the filter media and exits the filter through the outlet port.

Anti-drainback valve prevents oil loss

When the engine is off, the anti-drainback valve prevents oil from draining back into the oil pan.

Packaging and Delivery

Packaging: Neutral boxs / brown cartons/ Customize customers box.
Shipping: By air sea/rail

FAQ

Q: What does an oil filter do?

A: The oil filter helps remove contaminants from your car engine's oil that can accumulate over time as the oil keeps your engine clean. Clean motor oil is important because if the oil were left unfiltered for a period of time, it could become saturated with tiny, hard particles that can wear surfaces in your engine.

Q: How often should an oil filter be changed?

A: In general, most newer vehicles are designed to run on 6,000 or 7,500-mile cycles for oil changes (the old 3,000-mile cycle is a myth in terms of newer vehicles). Most mechanics agree that it's just a smart idea to have the filter swapped out every time you take your car in for an oil change.

Q: What is the best material for an oil filter?

A: Synthetic media offers more consistent porosity and smaller fiber size, which contributes to higher dirt-holding capacity, higher oil flow capacity and greater filter longevity. Microglass-media filters are produced with extremely fine glass fibers that are ten times thinner than cellulose fibers.

Q: What are the 5 main components of oil filter?

A: Inside of the filter are the anti-drainback valve, filter media, center support tube, pressure relief valve (sometimes referred to as the “bypass” valve) and tension spring. The materials used to manufacture each of the components are key to the lifespan of a spin-on oil filter.
